During the re-circulating of perfusate, the heart releases proteins
that cause foaming and the formation of embolites. To remove these proteins
and other precipitates that may exist in the solution, this filter is
inserted in the pump output line. The filter may then be removed at the
end of the experiment and replaced before the next experiment is started.
This is an improvement over systems that incorporate the filter as a permanent
fixture in the design, necessitating extensive cleaning procedures of
the entire apparatus after each use.
Polytetrafluorethylene (PTFE) membranes are unaffected by most
organic solvents, concentrated acids and bases, propellants, and cryogenic
fluids. Can be used for gas/air filtration. Use caution with syringes
less than 10cc. For laboratory use only.
