RE: glutaraldehyde

Make a heavy scratch, gouge, across the neck with a common small three cornered file available from almost any hardwared store. Follow the bending instructions from Ryuji as though you were trying to open the scratch up. That is, with the scratch away from you. The neck should break cleanly straight across along the scratch line.

Great description, Ryuji. Thanks everyone for suggestions; I haven't
gone ahead to act on them because it occurred to me that once the glass
is broken I'll have another problem: how then to store the excess
glutaraldehyde. So I'll need to obtain a little dropper bottle or
something first, before I break the ampule. "It's always somethin, ain't
it?" Thanks again,
