Differential Centrifuge

About differential centrifuge

In differential centrifuge the process of the centrifuge is processed several times when every time the sediment at the bottom is being removed and the centrifugal force is increased. After few times of purification processes performed by sedimentation equilibrium and the desire layer is taken for further analysis.


Industry’s CSK Group laboratory equipment suppliers explains how those centrifuges work.

Since different particles are coming in different sizes and different densities, each particle settles different in minimum centrifugal force. Thus the separation of the sample to different layers will be by centrifugation of the initial particle (e.g. cell content after dissolution) under week forces, removing sediment and then exposing the lotion to growing centrifugal forces. Every time different but specific material will be found at the bottom as sediment. An educated cycle of the method will provide different layers representing different parts of the original sample.


About centrifuges

Centrifuge is an instrument for separating materials, especially tiny particles suspended in liquid. The physical principal standing behind the method is the existence dependency between the aggregated material on walls of the centrifuge and the mass of its particles: With the rotation of the centrifuge, the particles in it are pushed toward the wall, but their density is in decline as they move away from the side – Materials with higher density, e.g. heavier, move and accumulate near the bottom of the test tube.

This action is called centrifuge and it’s being used much in biological research, in order to separate different materials. Example: use of centrifuge to isolate specific cell membranes or whole cells as part of creating the karyotype image.

Centrifuges in the industry

CSK Group the laboratory equipment suppliers explains the needs of centrifuges in the industry.

In certain industries centrifuges use to to separate the components of different specific mass mixed with a mixture. For example: in the process of uranium enrichment centrifuges are used to separate the two isotopes of the uranium in very high speed despite the tine mass difference between them. Another example is in dairy while using a centrifuge to separate the cream from the milk.

CSK Group – Laboratory Equipment Suppliers

Carbon Dioxide Incubator

Carbon Dioxide Incubator latest technologies

With the latest technologies for growing cell cultures platforms for large volume, the CSK Group CO2 Incubator designed the convenience of using and having a volume of 0.7m. In the chamber there is a precise temperature control, IR CO2 control and humidity.

In this unit there is a mechanism for removing moisture and heat automatically and makes cleaning during the night to prevent fungus and other infections. Temperature range is from 10C over the environmental temperature up to 60c and controlled by RTD in drift resistant that gives long-term temperature stability. The temperature sensor requires minimal calibration.

Standard Features

Standard features CSK Group the laboratory equipment suppliers contain much more.

Infrared CO2 sensor keeps the ranges of 0-20%. The sensor measures carbon dioxide only and after opening the door allows quick return desirable conditions, enabling cultures to remain constant pH levels.

The CO2 sensor gives great performance over time, so no need to keep track of the values with an external device or re-calibration.

The incubator comes with transport wheels and fits through standard doorways transition.

A horizontal flow diffuses the airflow on each shelf, no matter where in the chamber.

Internal units are made of stainless steel allowing easy cleaning and resistant to corrosion.

Heated 3 layered glasses reduces condensation on the door and helps return target temperature after opening.

Flotation Baths

Plain water baths and shaking – Metal

Water bath are designed to maintain a constant temperature of different cultures with the possibility of carrying. Regular flotation baths and vibrate are made of steel while this type of bath is coming with mechanical thermostat.

CSK Group provide variety of laboratory products among them many types of water bathes, acting as Laboratory Equipment Suppliers, CSK Group provide digital and analogic water bath up to 100 degrees. Water baths with two separate cells with 2 seprate temperature thermostat up to 100 degrees.

Another type of laboratory equipment water bath with temperature control is the one with dual and side transparent to heat extra sensitive samples that require constant observation of the heating material and full control of the temperature. Another option is laboratory water bath with water circulation – in a heating model only or heating and cooling model.

Polycarbonate water baths

Flotation bath made of polycarbonate, the price includes 18 months guarantee. The water bath comes with thermostat regulating the temperature of up to 100 degrees. The bath includes: thermostatic heating system and polycarbonate container. At the bottom of the bath pierced surface acting as shield to the heating body.

Laboratory water bath have many other possibility for extensions and additions such as transparent cover, stainless steel cover, cover with an open for bottles, net to hold the bottles and more.
