Appendix D: Chemical
Resistance
SRF110 Centrifugal Concentrator and Cold Trap are
designed to be chemical resistant to most compounds that
are commonly used in concentration processes. SRF110
have several enhancements to minimize chemical attack on
components. The lid, the chamber and rotors are Epoxy
coated, the rotor shaft is Stainless Steel, bearings are Steel,
the coupling insert is polypropylene and all wetted parts in the
vacuum release valves are made from Stainless Steel. Even
though parts in SRF110 are considerably resistant to
corrosion, it is very important that the SRF110 is immediately
cleaned and neutralized.
The following table gives the list of SRF110 compatible
