Chemical Resistance of CentriVap micro
IR Components

Your CentriVap micro IR Vacuum Concentrator is designed to be chemical
resistant to compounds that are commonly used in the concentration processes.
However, by necessity, the CentriVap is comprised of a number of different
materials, some of which may be attacked and degraded by certain 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:

A- Acceptable
C-Moderate Degradation-Questionable use
D-Severe Degradation-Infrequent use recommended-immediate thorough

cleaning required.

When using compounds in the CentriVap micro IR 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 using agents suitable for the substance involved.

• Remove the contents and clean the glass trap after each use.
