Maintenance

F. MAINTENANCE

The Equalizer pipette has been specifically designed for serviceability,
enabling the user to service instruments with relative ease. Under certain
circumstances where on-site service is not feasible, the instrument may need
to be returned to Thermo Fisher Scientific for repair

(see Pipette Service,

Sections G.2 and G3)

.

The Equalizer pipette requires very little maintenance. The exterior of the
pipette can be cleaned periodically with a soft cloth moistened with methyl
alcohol. Periodic cleaning of the tip fitting may be necessary using the
procedures for maintenance listed below.
In cases where pipettes have been exposed to biohazardous materials,
autoclaving internal components may be required. Thermo Fisher Scientific
provides the following Preventive Maintenance/Autoclave Kit:

Preventive Maintenance/Autoclave Kit

Replacement cross tubes

O-ring lubricant

Wooden applicator

O-rings

CAUTION! DO NOT AUTOCLAVE

entire unit or clean the keypad with bleach

solution or other solvents. Extreme heat can damage the display and other
electronic components. Caustic cleaning solutions can damage the keypad

or PCBs.

Note:

For autoclaving specific portions of the pipette refer to the autoclaving

steps in section F.1.2 for multichannel pipettes; or call technical service,
for instructions.

Note:

Avoid prolonged exposure to ultraviolet light. The handle housing may

become discolored or damaged.
