[NHCOLL-L:4071] RE: glass jars for alcohol collections

[Neumann Dirk]

The rubber sealing of Le Parfait glasses  may cause problems in the long 
run. The natural rubber gets crumbly over the years resulting in untight 
lots as far as I observed in our fish collection. This might be a 
problem of the denaturing agents added to the alcohol (2 % MEK in our 
collection) and / or traces of formalin released from the specimens.

In Europe, Grathwohl (Denmark) was providing collection glasses with a 
PE or PVC plastic liner. Glasses with PE liner work fine, but Grathwol 
offers the 75 ml nowadays only. The glasses work fine in collections 
with *undenatured* alcohol as preservative fluids, but especially PVC 
liners may cause problems with denaturing agents. Homepage Grathwol: 
http://www.grathwol.dk/ (Danish only)

We are using pharmaceutical glasses which are available up to 1000 ml. 
Glasses have plastic lids with a PE sealing in the liner, lids are ISO 
normed (= liners can be replaced easily when broken). You should look 
for a local provider in Sweden, because cost for transportation are much 
higher then the glasses themselves ....

Hope this helps
Dirk
