Hi folks,
Is there any consensus of opinion on whether the hot vapour from a MWPC (
containing say Tris/EDTA buffer )constitutes a significant health hazard
?We are debating whether it is acceptable to release the
pressure-regulating valve immediately to release the pressure , or to allow
the MWPC to cool down and let the pressure drop slowly prior to opening the
lid thus lowering the emmission of fumes to the atmosphere.Should opening
the MWPC be done in a fume cabinet anyway?The Tris and EDTA concentrations
involved are very low , but should we be concerned about their possible
effects?

I await your thoughts with interest,
Allan.
