Quality centrifuges from Sigma Laboratory Centrifuges: For efficient laboratory work

An important part of the workplace for our customers: the laboratory centrifuges from Sigma Laborzentrifugen. Among other things, the rotor is suitable for use in medical diagnostics, DNA research or for work in blood banks or clinical laboratories.

The laboratory centrifuges from Sigma Laboratory Centrifuges are characterized by the high durability, a lot of passes at the highest permissible speeds and their solid nature. Versatile! The 3-18KS is ideal for a wide range of separation operations. Depending on which model you choose, you can count on a colorful mix of features.

Most Sigma laboratory centrifuges come standard with features such as a control function, a timer function or an audible alarm, as well as a lid lock. The modern display allows you to select exactly the right program from a wide range. A modern microprocessor control ensures a smooth working process and control of the working process. The available safety system ensures that errors or faulty functions are immediately displayed and you can call up the corresponding report. The sustainable ventilation also protects the device from overheating.

Special features of the 3-18KS from Sigma Laboratory Centrifuges

Centrifuge type: Universal centrifuge
Dimensions (H x W x D): 355 x 630 x 600 mm
Display: TFT
Frequency: 50/60 Hz

When you choose universal centrifuges like the 3-18KS, you are choosing a real all-rounder. Due to its wide range of functions, the device is used in many different areas. These include both routine medical and veterinary tests, the use of various systems to obtain PRP, as well as the performance of numerous research tasks in clinical, medical or cosmetology laboratories.

A centrifuge basically works using the so-called mass inertia, which is why it is often used for activities such as substance separation. It is thus used, among other things, for the separation of blood and sera, but also emulsions or gas mixtures.

Swing-out rotors are really well suited for analytical as well as semi-preparative separation procedures.
