The Effect of Air Flow

Rigid shaft Drive System

Drive system

It is very hard to spin an angle rotor at speed higher than 23,000 rpm in the air. Therefore, a speed of more than 23,000 rpm can be achieved in a vacuum where air friction is reduced. It is impossible to use a rotor of high capacity such as 6x500ml without a vacuum at higher speed than 5,000rpm in a flexible shaft centrifuge, since it generates severe vibration of the shaft. Therefore, it is necessary to have a vacuum even at a speed of 9,000rpm un order to use a rotor of large capacity such as 6x500ml in a flexible shaft centrifuge. However, in the case of the Supra 30K/25K adapting rigid shaft, ti is possible to spin a rotor of 4x1,000ml without a vacuum at a speed of 9,000rpm

Sitting Rotors
Heavy rotors on a flexible shaft should ve taken out of the chamber after completion of centrifugation. Otherwise, the flexible shaft can change shape, which can lead to problems

Unnecessary standing by To reach the proper vacuum
For a centrifuge with a flexible shaft, it is necessary to wait until the vacuum reaches a certain level before starting the rotor to reduce friction caused by air flow at a high speed. However, for a centrifuge with a rigid shaft, you can start spinning the rotor with out a vacuum, During deceleration ain addition to acceleration, you can take the rotor out of the chamber right after it stops spinning.

Drive system of 3 fold Damper
Selection of a broad range of rotors
Light rotors cannot be used in a centrifuge with a flexible shaft designed for heavy rotors, and heavy rotors can not be used in a centrifuge with a flexible shaft designed for lighter rotors. the Supra 30K/25K adopting 3 fold damper driving system with a rigid shaft is de-signed to dffetively absorb the vibration generated by fixed angle rotors from small capacity rotors of 24x 15ml up to large capacity rotor sof 4 x 1.00
