Maintenance
2. Install new O-rings.
After the old O-rings have been removed and all components have been
autoclaved, the new O-rings may be installed. Before installing the O-rings,
apply a thin coat of lubricant to each O-ring, using the O-ring lubricant
supplied in the Preventive Maintenance/Autoclave Kit.
3. Re-lubrication
• 1250 μl and 250 μl Pipettes: Use the wooden applicator and O-ring
lubricant supplied in the Preventive Maintenance/Autoclave Kit to apply
a thin layer of lubricant approximately 0.5 inches (approx. 1.3 cm) down
into each piston hole that requires it. Spread the lubricant evenly along
the inner wall of each cylinder by using a circular motion with the wooden
applicator (see Figure F.1.3b).
