C-Moderate Degradation - Questionable use
D-Severe Degradation - Infrequent use recommended - immediate thorough
neutralizing and cleaning is required.
• If a rotary vane vacuum pump is used, frequent oil changes are required.
Most compounds used in the CentriVap will degrade the oil if allowed to
enter to pump.
• Diaphragm vacuum pumps sold by Labconco have wetted parts either made
from PTFE or protected by PTFE coatings and are suitable for nearly all
procedures.
• When using compounds in the CentriVap that are hostile to the materials of
construction, it is imperative that the equipment is appropriately maintained.
After each run, clean up all residues, spills and materials that might have
splashed in the chamber.
• Drain the Cold Trap immediately after the collected ice is melted to prevent
corrosive liquids from residing in the trap. Flush out the trap with water after
draining.
DO NOT chip ice off the Cold Trap walls as damage may occur.
DO NOT start a rotary vane pump when the Cold Trap contains any liquid.
The liquid will be drawn into the pump and will contaminate the vacuum
pump oil.
