Maintenance

1. After centrifugation, if it is no longer used on the same day, please dry the

centrifugation chamber with a clean soft cloth

Dirt from rotors and centrifuges. Open the door cover to help evaporate the water in the

centrifugal chamber.

2. Check the rotor and centrifugal pipe regularly for cracks.

3.When the instrument needs to stop using for more than one month, please take out

the rotor from the centrifugal chamber, apply a thin layer of grease to the center hole of the

rotor and the main shaft of the centrifuge, and keep the rotor in a dry place.
