8KS from Sigma Laboratory Centrifuges: Excellent centrifuge for your applications

With the 8KS from Sigma Laboratory Centrifuges, you ensure efficient work in the laboratory. You can make excellent use of the instrument for work in clinical laboratories, for use in blood banks, for DNA research or in medical diagnostics.

All our robust centrifuges are characterized by a long service life, a large number of passes at the highest permissible speeds and their robust construction. You can use the 8KS very flexibly and individually. The model is ideally suited for all types of separation processes. Depending on which model you choose, you can count on a colourful mix of additional features.

For example, most Sigma laboratory centrifuges come with features such as monitoring, a timer function or an acoustic alarm as well as a lid lock as standard. The user-friendly display allows you to choose exactly what you need from a wide range of programs. A sophisticated microprocessor control ensures a reliable workflow and control of the working process. An existing safety system regularly transmits information about error messages or malfunctions. Furthermore, the instrument has an energy-saving ventilation system that protects it from overheating.

Are you looking for a space-saving centrifuge model? Then the 8KS floor-standing centrifuge from Sigma Laboratory Centrifuges is the right choice for you, as its modern design allows it to be optimally moved and stowed away.

It works by exploiting the physical aspect of mass inertia and is used, among other things, for separating substances. It is thus used, for example, for the separation of gas mixtures, emulsions or suspensions.

The swing-out rotor 8KS can be used, for example, for semi-preparative but also for analytical separation applications.
