Dear colleagues,
I posted the message below yesterday, but it seems not to have reached the listmembers. Hereby a new attempt.
After having been moved to a new building with new laboratory facilities (and all chemicals having to be bought anew), I would like to reconsider our method of storing waterlogged archaeobotanical material. Up to now, in our lab this storage is either in formaldehyde or in a mixture of 50 vol%/50 vol% water and glycerin with 6 gr of phenol per liter.
Seeing the serious health risks of both formaldehyde and phenol, I am seeking for an alternative. Benzoic acid seems to have been tested, but I would be happy to hear of any experiences with this, and also practical matters as concentration, dissolving, etc. I have already had contacts with some of you about this, but I don't feel that I have any final answers (so please forgive me again rising the matter).
Please also note that my mail address has changed to: [log in to unmask]
With kind regards,
oTTo
