Re: glutaraldehyde source



That product description sounds like a dilute solution of
glutaraldehyde but it doesn't say if there's anything else in
it. In case of Maxicide I figured it has a bit of corrosion
inhibitor (nitrate salt), a mild acid, and surfactant, none
of which would affect photographic performance. That's the
tricky part of using a proprietary product for uses other than
the intended one...

Also, plain dilute glutaraldehyde adjusted to pH of about 4
always worked well for me.

When buying glutaraldehyde, avoid concentrated stock unless
you have a fume hood to work with. Although glut can be
handled in a well ventilated darkroom once diluted to 0.5 to
2.5%, concentrated glut should be handled always with
an appropriate level of lab safety precaution.
