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. -- Ryuji Suzuki "Strange how people who suffer together have stronger connections than people who are most content."
