I felt that this would be a good place to ask this question and
hopefully I will get lots of good advice:
I want to know if anyone knows where and/or how I can puchase
2.5% calcium gluconate gel.
I have purchased hydroflouric acid from Aldrich Chemical Co. and
in their MSDS sheet they recomend this gel as a neutralizing agent if you
should happen to get any HF on your skin. I am quite aware of how
extremely dangerous HF is and I do not want to use it for any of my
etching experiments until I have all my safety precautions taken care
of.
I called Aldrich and they do not sell the calcium gluconate and
they were of absolutely no help in letting me know where I could find it
and they did not give me any readily available alternatives.
Does anybody have any clues or suggestions as to where I can get
this calcium gluconate gel or for that matter, do you have any
helpful suggestions about dealing with this extremely nasty chemical. If
I had my choice I would not use it at all, but I must.

Aldrich and Sigma--all have gluconates, and Aldrich and Sigma have
Ca-salts (you could, of course, add CaOH to the acid if need be). I guess that
adding the right amount of H2O will give the 2.5% gel.
Use it in a hood, wear a lab coat and polyethylene gloves,
and use goggles or a face shield. H2F2 is an inhalation hazard, so
make sure your hood has adequate air flow. H2F2 is nasty, but not as nasty
as some of the chemicals in use in organic chem labs. Good luck.

We also keep zephiran chloride solution on hand to assist in
treatment.

I do not not if this might help you. I am using HF on a regular
basis. Here in Australia I can get the Calcium Gluconate Gel
from ORION - Laboratories P/L - Briggs Street - Welshpool -
Western Australia.
