Chemical Resistance of CentriVap Components
Your CentriVap Centrifugal Concentrator and Cold Trap are designed to be
chemical resistant to most compounds that are commonly used in concentration
processes. However, by necessity, the CentriVap is comprised of a number of
different materials, some of which may be attacked and degraded by corrosive
chemicals. The degree of degradation is obviously dependent on the concentration
and duration of exposure. Some major components of the CentriVap that are
susceptible to degradation are as follows:
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 Teflon or protected by Teflon 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.
