Chapter 4:
Maintaining Your CentriVap Cold
Trap
Under normal operation, the CentriVap Cold Trap requires little maintenance.
The following maintenance schedule is recommended. Before servicing the Cold
Trap, disconnect electrical power. Special precautions must be observed if
materials used in the CentriVap Cold Trap are known to be hazardous, toxic,
radioactive or contaminated with biohazardous. Before servicing, the CentriVap
Cold Trap must be suitably decontaminated. Wear appropriate eyewear, gloves
and other safety apparel.
As needed:
Before using any cleaning or decontamination method except those recommended
by the manufacturer, users should check with the manufacturer that the proposed
method will not damage equipment.
1. Clean up all spills; remove liquids from the chamber. Clean or decontaminate
all surfaces using agents suitable for the substance spilled.
2. Clean lid and gasket using soft cloth, sponge or chamois and a mild, non-
abrasive soap or detergent.
3. Check oil level of the vacuum pump, if applicable. It should be between MIN
and MAX.
4. If oil shows cloudiness, particles or discoloration, drain the pump and replace
with fresh oil.
5. Utilization of acids requires immediate cleaning and neutralization after a run
or physical damage to the collection chamber will result.
6. Check the Cold Trap for condensed or frozen solvents and dispose of
appropriately. Completely empty the trap before the next run. The Cold Trap
cover is removed by first lifting and rotating the two retainers that secure the
lid in place. If solvents are frozen in the glass trap, run it under cold water
immediately after operating.
