V&P Scientific also offers stirrers
that are coated with parylene, for those applications (combinatorial chemistry) where Fe molecules may interfere with
the reaction, or the stirrers would be attacked by strong acids
or bases. Parylene (Di-Para-Xylylene) is deposited on the surface
of the stirrer in a very uniform 0.05 mm thick layer, thus
protecting the stirrers from strong acids and bases. Parylene
coated stirrers can be autoclaved or sterilized in hot air ovens
without harming the conformal coating. Parylene can be heated to 200°C without
harming the surface. Parylene is also
compatible with biological applications. In fact, parylene is used to coat
materials for implant procedures, as it is completely non-toxic
to tissues. A very complete discussion of
barrier characteristics, properties and methods of deposition is found at
this hyperlink. Another page is dedicated to
organic solvents, acids and bases.
The Parylene Coated Tumble Stirrers can be dispensed with the same
as their non-coated counterparts.
