Practical laboratory centrifuge from Sigma Laboratory Centrifuges

The 3-18KHS from Sigma Laboratory Centrifuges has become an important part of laboratory equipment over the last few years. The instrument is particularly suitable not only for clinical laboratories but also for use in blood banks, for DNA research or in medical diagnostics.

All centrifuges of our manufacturers are characterized by the special longevity, a large number of runs at the highest permissible speeds and their powerful nature. The 3-18KHS is the optimal centrifuge for any type of separation process and can be used in a wide range of applications. Depending on which model you choose, you can expect a mix of features.

Most Sigma laboratory centrifuges come standard with features such as a control function, timer and audible alarm, as well as a lid lock. The user-friendly display allows you to select exactly those programs that meet your needs from a wide range of programs without much effort. A modern microprocessor control ensures an orderly workflow as well as control of the working process. An integrated safety system regularly transmits information about error messages or malfunctions. The efficient ventilation system is also part of the 3-18KHS.

Further product information about the 3-18KHS

The universal centrifuges from Sigma Laboratory Centrifuges are true multi-talents. They are just as suitable for routine tests and separation procedures as they are for the thorough preparation of diverse samples in numerous fields of application. A special selection of rotors and programs as well as other extras enable you to work extremely precisely. The modern software, which has the latest safety standards, is standard here. The minimal noise level ensures a pleasant atmosphere and optimal conditions for concentration at the workplace.

The device works by exploiting the physical aspect of inertia, which is why it is usually used for work such as material separation. It is thus used, among other things, for the separation of gas mixtures, emulsions or suspensions.

A swing-out rotor is very suitable for analytical as well as semi-preparative separation processes.
