You will learn about "Solution, Suspension and Colloid" in this video. Let us understand this with the help of an activity. Take some water in 3 separate beakers. Add sugar in the 1st beaker, chalk powder in the 2nd beaker and some milk in the 3rd beaker. Stir all the mixtures.
Now, direct a beam of light from a torch through these beakers. In the 1st mixture, the particles of sugar have completely disappeared in the mixture. Such a mixture is called a homogenous mixture. (Homogenous means consistent or uniform throughout). When light is directed through the 1st beaker, we are unable to see the path of the light inside the homogenous mixture. As the particles of sugar are very small, they cannot scatter any light. Such a mixture is called a solution. Here, the size of particles is usually less than 1 nm.
In the 2nd mixture, we can observe some chalk particles freely moving in the water. Such a mixture is called a heterogeneous mixture. ( Heterogeneous means non-uniform) Size of particles in a suspension is usually larger than 1000 nm. When light is directed through the 2nd beaker, the path of light is visible inside the heterogeneous mixture.
The particles of chalk are insoluble in water and are big enough to scatter the light passing through them. Such a mixture is called a suspension and this effect of scattering of light is called Tyndall effect. However, these particles eventually settle down. So, therefore after some time, the Tyndall effect may not be observed in suspensions.
Now, let us have a look at the 3rd mixture. Here also, the path of light is visible through the mixture. This mixture appears to be homogenous, but when observed under a highly powered microscope, it is actually a heterogeneous mixture. Such a mixture is called a colloid. Here, the size of particles is between 1 nm and 1000 nm. In a colloid, the particles never settle down. Hence, the Tyndall effect is always observed in colloids.

Colloid is a heterogeneous substance (with 2 or more phases) consisting of insoluble particles dispersed in continuous medium. It can also be referred as a dispersion phase (e.g. milk powder) in a dispersant phase (e.g. water). The particles are well-distributed in the medium and will only settle down to the bottom of the container after a very long period of time. They can be an aggregate of tiny molecules or one big molecule. The properties of colloid is located in between a suspension and solution. For example, a typical colloidal particle has diameter around 0.002 - 0.2 mm, which is normally bigger than particles found in a solution and smaller than particles in suspension. The particles might be bigger than the solute in solution, but they still too small in size to settle down only by gravitational force.
Another significant property of colloid is its ability to scatter or absorb beam of light or better known as Tyndall Effect which is defined as the scattering of light by particles in a colloid. It is due to colloidal particles having diameter which is very close to the wavelength of the light passes through it. Similar result can also be obtained if the distances between colloidal particles are comparable to the wavelength of the light. Visible light has wavelength ranging from 350 to 700 nm, and it is almost the same as the diameter of colloidal particle.
The colloids chosen for the experiment is milk particles in water. The aim of this experiment is to prove that light gets scattered in colloids and the path of scattered light can be seen by naked eye. Two beakers, a pack of milk and a laser pointer are prepared for this experiment. In the beginning, two beakers locating side by side are filled with water and light is being shone through both beakers. No light path is observed because the molecules of water are too small to scatter the light. After that, a small amount of milk is poured into the beaker and stirred to obtain a colloid. As a result, a clear bright red light path passing through the beaker is seen. This shows that Tyndall effect only applies to colloid.
Tyndall effect is mainly used when dealing with colloidal particles. For example, Tyndall effect is used in waste water treatment to examine the pollution level of water. Besides that, food industry also utilise this effect to detect presence of contaminants in different fluids. Furthermore, it is also very important in pharmaceutical industry to observe microbiological cultures. Last but not least, pulp and paper industry uses Tyndall effect to monitor the clarity of the mild acids used in the production of paper.

"Endoscopic resection of colloid cyst in normal-sized ventricular system"
Konstantinos Margetis, MD and Mark M. Souweidame, MD
Department of Neurological Surgery, Weill Cornell Medical College, New York, New York
Endoscopic resection of colloid cyst in patients with normal-sized ventricular system is challenging, because the limited intraventricular space increases the risk of injuring eloquent nervous structures and critical blood vessels. The utilization of frameless stereotaxy and tissue shaving device facilitates the procedure. An important operative step is the ventricular insufflation that allows for an endoscope introduction without causing inadvertent injury to the caudate nucleus. The attached clip shows the basic operative steps of the procedure. In this clip the solid colloid cyst contents necessitated an en-block colloid cyst resection, in lieu of initially aspirating the cyst contents and subsequently removing the cyst walls.

A colloid is a substance microscopically dispersed evenly throughout another substance.
A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed. A colloidal system may be solid, liquid, or gas.
The dispersed-phase particles have a diameter of between approximately 1 and 1000 nanometers. Such particles are normally invisible in an optical microscope, though their presence can be confirmed with the use of an ultramicroscope or an electron microscope. Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols, colloidal emulsions, colloidal foams, colloidal dispersions, or hydrosols. The dispersed-phase particles or droplets are affected largely by the surface chemistry present in the colloid.
Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color.

Colloid mill is specially designed for the production of highly stable colloidal solutions, extremely fine suspensions, mixtures and emulsions. http://mill.globecore.com/colloid-mills/catalogue/colloid-mill/klm-4.html “Wet” grinding technique is used, as the rotor and stator cone gap is wider at the inlet and narrower at the outlet. Additionally, the complex micro relief of the generator (stator) surface creates increased turbulence, shearing the particles. Under the influence of centrifugal force and high velocity of the rotor relative to the stator, liquid and semi-liquid substances are finely dispersed and homogenized, any mix of materials are also emulsified, homogenized and dispersed. http://mill.globecore.com/colloid-mills/catalogue/colloid-mill/klm-4.html Colloid mills and their modifications are applied in: +road-construction industry – for bitumen modification by polymers etc, for producing anionic and cationic bitumen emulsions, liquid rubber and so on. +machine-building industry – for production of lubricating and cooling emulsions, lubricants, process mediums for cooling in heat intensive processes. +power industry – for “heavy oil + water” emulsion production and burning in boiler houses and other power generation systems (reduces heavy oil consumption by 7-10% due to increased degree of combustion efficiency, boiler efficiency increase by 2-3%, decrease of carbon and nitrogen oxide emissions to the atmosphere up to 50%, waste product disposal). Conversion of liquid oil waste products into fuel (oil refinery, seaport, industrial waste). Mixing of stable fuel emulsions from oil sludge. +chemical industry – for improvement of interphase component contact in multiphase heterogeneous systems, for extracting, for oil product and waste water purification, for production of household chemicals, glues, varnishes, polishes and antiseptics. +varnish-and-paint industry – for paint production. +food industry – for dairy processing, for fat emulsion production, for corn starch production, for making of fruit puree, mayonnaise, yoghurts, soft cheese, kefir, condensed milk, melted cheese, for milk powder and cream recovery. +pharmaceutical, perfumery and cosmetic industries – for production of high quality stable shampoos, gels, creams, emulsions, medical products, ointments, pastes.

Colloids: Tyndall Effect
Colloid is a heterogeneous substance (with 2 or more phases) consisting of insoluble particles dispersed in continuous medium. It can also be referred as a dispersion phase (e.g. milk powder) in a dispersant phase (e.g. water). The particles are well-distributed in the medium and will only settle down to the bottom of the container after a very long period of time. They can be an aggregate of tiny molecules or one big molecule. The properties of colloid is located in between a suspension and solution. For example, a typical colloidal particle has diameter around 0.002 - 0.2 mm, which is normally bigger than particles found in a solution and smaller than particles in suspension. The particles might be bigger than the solute in solution, but they still too small in size to settle down only b... -

Endoscopic resection of colloid cyst in normal-sized ventricular system
"Endoscopic resection of colloid cyst in normal-sized ventricular system" Konstantinos Margetis, MD and Mark M. Souweidame, MD Department of Neurological Surgery, Weill Cornell Medical College, New York, New York Endoscopic resection of colloid cyst in patients with normal-sized ventricular system is challenging, because the limited intraventricular space increases the risk of injuring eloquent nervous structures and critical blood vessels. The utilization of frameless stereotaxy and tissue shaving device facilitates the procedure. An important operative step is the ventricular insufflation that allows for an endoscope introduction without causing inadvertent injury to the caudate nucleus. The attached clip shows the basic operative steps of the procedure. In this clip the solid colloid ... -

GlobeCore Colloid Mill animation
Colloid mill is specially designed for the production of highly stable colloidal solutions, extremely fine suspensions, mixtures and emulsions. http://mill.globecore.com/colloid-mills/catalogue/colloid-mill/klm-4.html “Wet” grinding technique is used, as the rotor and stator cone gap is wider at the inlet and narrower at the outlet. Additionally, the complex micro relief of the generator (stator) surface creates increased turbulence, shearing the particles. Under the influence of centrifugal force and high velocity of the rotor relative to the stator, liquid and semi-liquid substances are finely dispersed and homogenized, any mix of materials are also emulsified, homogenized and dispersed. http://mill.globecore.com/colloid-mills/catalogue/colloid-mill/klm-4.html Colloid mills and thei... -

Colloid - Video Learning - WizScience.com
A "colloid" is a substance in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term "colloidal suspension" refers unambiguously to the overall mixture . Unlike a solution, whose solute and solvent constitute only one phase, a colloid has a dispersed phase and a continuous phase . To qualify as a colloid, the mixture must be one that does not settle or would take a very long time to settle appreciably. The dispersed-phase particles have a diameter of between approximately 1 and 1000 nanometers. Such particles are normally easily visible in an optical microscope, although at the smaller size range , an ultramicroscope or an electron microscope may be requi... -

You will learn about "Solution, Suspension and Colloid" in this video. Let us understand this with the help of an activity. Take some water in 3 separate beakers. Add sugar in the 1st beaker, chalk powder in the 2nd beaker and some milk in the 3rd beaker. Stir all the mixtures.
Now, direct a beam of light from a torch through these beakers. In the 1st mixture, the particles of sugar have completely disappeared in the mixture. Such a mixture is called a homogenous mixture. (Homogenous means consistent or uniform throughout). When light is directed through the 1st beaker, we are unable to see the path of the light inside the homogenous mixture. As the particles of sugar are very small, they cannot scatter any light. Such a mixture is called a solution. Here, the size of particles is usually less than 1 nm.
In the 2nd mixture, we can observe some chalk particles freely moving in the water. Such a mixture is called a heterogeneous mixture. ( Heterogeneous means non-uniform) Size of particles in a suspension is usually larger than 1000 nm. When light is directed through the 2nd beaker, the path of light is visible inside the heterogeneous mixture.
The particles of chalk are insoluble in water and are big enough to scatter the light passing through them. Such a mixture is called a suspension and this effect of scattering of light is called Tyndall effect. However, these particles eventually settle down. So, therefore after some time, the Tyndall effect may not be observed in suspensions.
Now, let us have a look at the 3rd mixture. Here also, the path of light is visible through the mixture. This mixture appears to be homogenous, but when observed under a highly powered microscope, it is actually a heterogeneous mixture. Such a mixture is called a colloid. Here, the size of particles is between 1 nm and 1000 nm. In a colloid, the particles never settle down. Hence, the Tyndall effect is always observed in colloids.

Colloid is a heterogeneous substance (with 2 or more phases) consisting of insoluble particles dispersed in continuous medium. It can also be referred as a dispersion phase (e.g. milk powder) in a dispersant phase (e.g. water). The particles are well-distributed in the medium and will only settle down to the bottom of the container after a very long period of time. They can be an aggregate of tiny molecules or one big molecule. The properties of colloid is located in between a suspension and solution. For example, a typical colloidal particle has diameter around 0.002 - 0.2 mm, which is normally bigger than particles found in a solution and smaller than particles in suspension. The particles might be bigger than the solute in solution, but they still too small in size to settle down only by gravitational force.
Another significant property of colloid is its ability to scatter or absorb beam of light or better known as Tyndall Effect which is defined as the scattering of light by particles in a colloid. It is due to colloidal particles having diameter which is very close to the wavelength of the light passes through it. Similar result can also be obtained if the distances between colloidal particles are comparable to the wavelength of the light. Visible light has wavelength ranging from 350 to 700 nm, and it is almost the same as the diameter of colloidal particle.
The colloids chosen for the experiment is milk particles in water. The aim of this experiment is to prove that light gets scattered in colloids and the path of scattered light can be seen by naked eye. Two beakers, a pack of milk and a laser pointer are prepared for this experiment. In the beginning, two beakers locating side by side are filled with water and light is being shone through both beakers. No light path is observed because the molecules of water are too small to scatter the light. After that, a small amount of milk is poured into the beaker and stirred to obtain a colloid. As a result, a clear bright red light path passing through the beaker is seen. This shows that Tyndall effect only applies to colloid.
Tyndall effect is mainly used when dealing with colloidal particles. For example, Tyndall effect is used in waste water treatment to examine the pollution level of water. Besides that, food industry also utilise this effect to detect presence of contaminants in different fluids. Furthermore, it is also very important in pharmaceutical industry to observe microbiological cultures. Last but not least, pulp and paper industry uses Tyndall effect to monitor the clarity of the mild acids used in the production of paper.

Endoscopic resection of colloid cyst in patients with normal-sized ventricular system is challenging, because the limited intraventricular space increases the risk of injuring eloquent nervous structures and critical blood vessels. The utilization of frameless stereotaxy and tissue shaving device facilitates the procedure. An important operative step is the ventricular insufflation that allows for an endoscope introduction without causing inadvertent injury to the caudate nucleus. The attached clip shows the basic operative steps of the procedure. In this clip the solid colloid cyst contents necessitated an en-block colloid cyst resection, in lieu of initially aspirating the cyst contents and subsequently removing the cyst walls.

Colloid mill is specially designed for the production of highly stable colloidal solutions, extremely fine suspensions, mixtures and emulsions.
http://mill.globecore.com/colloid-mills/catalogue/colloid-mill/klm-4.html
“Wet” grinding technique is used, as the rotor and stator cone gap is wider at the inlet and narrower at the outlet. Additionally, the complex micro relief of the generator (stator) surface creates increased turbulence, shearing the particles.
Under the influence of centrifugal force and high velocity of the rotor relative to the stator, liquid and semi-liquid substances are finely dispersed and homogenized, any mix of materials are also emulsified, homogenized and dispersed.
http://mill.globecore.com/colloid-mills/catalogue/colloid-mill/klm-4.html
Colloid mills and their modifications are
applied in:
+road-construction industry – for bitumen modification by polymers etc, for producing anionic and cationic bitumen emulsions, liquid rubber and so on.
+machine-building industry – for production of lubricating and cooling emulsions, lubricants, process mediums for cooling in heat intensive processes.
+power industry – for “heavy oil + water” emulsion production and burning in boiler houses and other power generation systems (reduces heavy oil consumption by 7-10% due to increased degree of combustion efficiency, boiler efficiency increase by 2-3%, decrease of carbon and nitrogen oxide emissions to the atmosphere up to 50%, waste product disposal). Conversion of liquid oil waste products into fuel (oil refinery, seaport, industrial waste). Mixing of stable fuel emulsions from oil sludge.
+chemical industry – for improvement of interphase component contact in multiphase heterogeneous systems, for extracting, for oil product and waste water purification, for production of household chemicals, glues, varnishes, polishes and antiseptics.
+varnish-and-paint industry – for paint production.
+food industry – for dairy processing, for fat emulsion production, for corn starch production, for making of fruit puree, mayonnaise, yoghurts, soft cheese, kefir, condensed milk, melted cheese, for milk powder and cream recovery.
+pharmaceutical, perfumery and cosmetic industries – for production of high quality stable shampoos, gels, creams, emulsions, medical products, ointments, pastes.

A "colloid" is a substance in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term "colloidal suspension" refers unambiguously to the overall mixture . Unlike a solution, whose solute and solvent constitute only one phase, a colloid has a dispersed phase and a continuous phase . To qualify as a colloid, the mixture must be one that does not settle or would take a very long time to settle appreciably.
The dispersed-phase particles have a diameter of between approximately 1 and 1000 nanometers. Such particles are normally easily visible in an optical microscope, although at the smaller size range , an ultramicroscope or an electron microscope may be required. Homogeneous mixtures with a dispersed phase in this size range may be called "colloidal aerosols", "colloidal emulsions", "colloidal foams", "colloidal dispersions", or "hydrosols". The dispersed-phase particles or droplets are affected largely by the surface chemistry present in the colloid.
Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color.
Colloidal suspensions are the subject of interface and colloid science. This field of study was introduced in 1861 by Scottish scientist Thomas Graham.
Because the size of the dispersed phase may be difficult to measure, and because colloids have the appearance of solutions, colloids are sometimes identified and characterized by their physico-chemical and transport properties. For example, if a colloid consists of a solid phase dispersed in a liquid, the solid particles will not diffuse through a membrane, whereas with a true solution the dissolved ions or molecules will diffuse through a membrane. Because of the size exclusion, the colloidal particles are unable to pass through the pores of an ultrafiltration membrane with a size smaller than their own dimension. The smaller the size of the pore of the ultrafiltration membrane, the lower the concentration of the dispersed colloidal particles remaining in the ultrafiltered liquid. The measured value of the concentration of a truly dissolved species will thus depend on the experimental conditions applied to separate it from the colloidal particles also dispersed in the liquid. This is particularly important for solubility studies of readily hydrolyzed species such as Al, Eu, Am, Cm, or organic matter complexing these species.
