3-30KHS from Sigma Laboratory Centrifuges: Efficient centrifuge for routine laboratory work

Indispensable for our customers and partners: the laboratory centrifuges from Sigma Laborzentrifugen. In addition to clinical laboratories, for example, the instrument is also suitable for use in blood banks, for DNA research or in medical diagnostics.

You can use the 3-30KHS for a lot of runs at the maximum allowed speeds. It can be used quite flexibly and is suitable for many types of separation processes. Depending on the model, the centrifuges from Sigma Laboratory Centrifuges have a versatile mix of additional parts and additional extras.

Most Sigma laboratory centrifuges are equipped with features such as a monitoring function, a timer function or an acoustic alarm as well as a lid lock. The practical display allows you to select exactly those programs that meet your process requirements in just a few steps. A reliable microprocessor control ensures an orderly process and control of the working process. An available safety system gives you regular information about error messages or malfunctions. In addition, the instrument has a sustainable running system, which prevents it from overheating.

Special features of the 3-30KHS from Sigma Laboratory Centrifuges

Centrifuge type: Universal centrifuge
Dimensions (H x W x D): 460 x 570 x 616 mm
Display: TFT
Programs: 60
Control: Lockable control

Universal centrifuges such as the 3-30KHS from Sigma Laboratory Centrifuges are true all-rounders. They are suitable for routine tests and separation procedures as well as for the thorough preparation of various samples in numerous fields of application. Many rotors, a wide range of programs as well as further accessories enable you to work very gently and accurately. Innovative software, equipped with the latest safety standards, works reliably and will not let you down. The minimal noise level ensures a relaxed atmosphere at the workplace.

In general, a centrifuge applies the physical aspect of inertia, which is why it is often used for work such as substance separation. Blood and sera, suspensions, gas mixtures or emulsions can be separated quickly and easily with the instrument.

Are you looking for a laboratory instrument that performs both analytical and semi-preparative separations? Then the 3-30KHS swing-out rotor from Sigma Laboratory Centrifuges is exactly the perfect choice.
