Rotors
Sigma Laboratory Centrifuges

Sigma supplies matching fixed-angle, swing-out and drum rotors for all Sigma centrifuges. Sigma rotors are precision-made from modern, certified high-performance materials with traceable batch numbers. Thanks to many years of experience and close contact with our customers, we are able to offer an extensive selection of rotors. Sigma rotors are characterised by extra capacity or higher maximum speed. Rotors can be operated continuously at maximum speed and +4°C in nearly all Sigma centrifuges.

With low maintenance effort, Sigma rotors can be used for very many cycles with maximum load and at maximum speed, in most cases up to 50,000 cycles. In addition to current models, rotors are also available for discontinued product lines.

The new Sigma 2-7 Cyto combines the highlights of Sigma 2-7 with state-of-the-art cytocentrifugation technology. It accommodates closed cytology rotors capable of carrying a maximum of twelve RESOPSIN® or Shandon™ cytology clips. The closed and easily removable cytology rotors ensure outstanding safety measures. Loading and unloading of the rotor can take place under the safety cabinet protecting user and sample before, during and after the centrifugal run. The compact centrifuge saves space in the laboratory, especially by the possibility to mount a 4 x 100 ml swing-out rotor for cell harvest in one and the same centrifuge. With its maximum speed of 2,000 rpm and two sets of acceleration and breaking profiles, Sigma 2-7 Cyto is perfectly suited for centrifugation of sensitive cytology samples and cells requiring gentle handling. Only available outside of Germany. In Germany, please contact our partner RESOLAB (www.resolab.de/) for RESOSPIN PRO®.
