What is Sigma comfort coating?
Cleaning and maintaining 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 and causing the centrifuge to stop.
Sigma have developed Comfort Coating which is a black coating on the rotor pins that has an anti-friction property. Sigma Comfort rotors eliminate the need for regular greasing of the rotor pins that support the buckets, making daily maintenance of the centrifuge a lot easier and ensures safe operation of the unit by preventing imbalances.
Rotors with the Sigma Comfort coating can easily be identified by the “C” after the product number, for example 11180 C.
How long does the coating last?
The Comfort Coating allows rotors and buckets to operate together smoothly for up to five years (depending on intensity of use) in typical laboratory applications, without the need for routine lubrication. To maximise the lifetime of the coating, always load the rotor with the individual buckets mounted in the same position. Over time, the black coating will show minor signs of wear, but this certainly does not indicate the end of its lifetime. Once the black Comfort coating completely wears off, you can replace the rotor and buckets or simply continue with conventional greasing of the pins.
