Comfort coating

• Cleaning and caring for centrifuges and accessories is vital for long-term safe operation and optimal separation results.
• With swing-out rotors, regular greasing of the pins that carry the buckets is very important.
• Irregular or no greasing makes it difficult for the buckets to swing out, leading to imbalance.

No more greasing

• Thanks to the new Sigma Comfort coating, Sigma Comfort rotors no longer need to be greased.
• The rotor and buckets will comfortably operate together for several years – with no need for regular greasing.
• For typical applications in normal labs, the Sigma Comfort coating will last for up to 5 years.
• The lifetime of the black coating depends on the intensity of use and therefore may vary.
• Thanks to the black Comfort coating of Sigma rotor pins, Sigma Comfort rotors no longer need to be greased.

• To maximize the lifetime of the coating, always load the rotor with the individual buckets mounted in the same place. 
• Over time, the black coating will show minor signs of wear, but this certainly does not indicate the end of its lifetime.
• If the black Comfort coating wears off completely after several years, replace the rotor and buckets or simply continue  with conventional greasing. 
• Clean chamber Another advantage of the Comfort coating is that the centrifuge chamber stays clean: the Sigma Comfort coated rotors eliminate the usual grease line in the centrifuge  chamber. 
• Rotors with the Sigma Comfort coating can easily be recognized by the “C” after the item number. For example 11180 C.
