The minimum retention time means the environmental temperature

Part 7 Maintenance

1. You should take out the rotors from the centrifugal chamber when you don't use the machine for a long time, and then store them in the ventilation and dry place after cleaning.

2. Clean the centrifugal chamber when finished centrifugation, dismantle the central sleeve from the axle regularly, and lubricate the axle and central sleeve, in case of corrosion.

3. Keep the place which settle the centrifuge clean, make sure the freezer is not choked by dirty subjects.

Remark

Regarding how to select RCF parameter

1. The principle of the centrifugation

Centrifuge will produce RCF during operation. Due to sedimentation caused by RCF make the subject dangling in the solution to form precipitation. The substance of the more proportion turned the direction of the largest radius rotor, the lighter substance is on heavier substance and let the subjects of different proportion to be separated hierarchically.

2. How to calculate the relative centrifugal force (RCF)

Centrifugation is depending on the RCF, RCF is depending on the speed and centrifugal radius, the formula of calculating the RCF as follows:

The transfer coefficient 11.2 is a approx value, which is calculating according acceleration of gravity(1g = 9.81m/s2)

3. The confirmation of centrifugal time

Same RCF, centrifugation time is inversely proportional to centrifugal solution's proportion description. The more of the proportion, the less of the time. The less of the proportion, the more of the time.

Same solution, centrifugation time is inversely proportional to RCF. The bigger RCF, the less of the time. Contrary, the smaller RCF, the more of the time.

Same RCF, centrifugation time is related to Min centrifugal radius, longer basket(test bottles) require a longer centrifugation time.

Therefore, the separation time is difficult to calculate. Usually it is decided by the general test.
