(2) Centrifugal chamber
•
If the centrifuge chamber becomes dirty, clean it using a cloth/ sponge soaked with neutral cleaning
agent.
•
The centrifuge chamber can be sterilized using a cloth soaked in 70% alcohol solvent.
(3) Drive shaft
•
It is suggested that the drive shaft should be subjected to periodical maintenance by wiping it using a
piece of soft cloth and applying a thin layer of silicone grease on it.
(4) Upper cover
•
Clean or sterilize the upper cover in the same manner as that of centrifuge(1).
(5) Rotor
•
If the rotor is put out of service for a prolonged period of time, please remove the rotor from the
centrifugal chamber, remove the rotor’s lid and place the rotor upside down to dry the rotor hole and
prevent corrosion.
•
If any sample leaks into the rotor hole, flush the rotor hole with clean water and apply a thin layer of
silicone grease on the rotor surface after it is dried.
•
The rotor needs periodical maintenance. It is suggested that the rotor should be cleaned once every
three months to ensure cleanliness of the tube hole and main shaft hole before applying a thin layer of
silicone grease.

9.3 Routine check
(1) Check whether the tabletop on which the centrifuge is placed is solid, level and flat and ensure the four
feet of the centrifuge remain in contact with the tabletop.
(2) Check whether the machine is reliably grounded, using a multi-meter. Check whether the grounding
pin in the power cable, centrifugal chamber and motor shaft are short-circuited. A short-circuit indicates a
Caution
•
Never directly pour water or other solvents into the centrifugal chamber as these solvents might enter
into the drive unit and cause corrosion or damage to the bearings.
