[Nhcoll-l] [EXTERN] Material of rubber seal

[Dirk Neumann]

Hi Lennart,

if you refer to Le-Perfait gaskets, the baseline should be

Replacement gaskets should be made of a durable but elastic synthetic material such as neoprene or Buna-N (acrylonitrile butadiene rubber, also called nitrile).

For Europe, there seems to be a vendor in Switzerland (Fabian do you have more details?)

With best wishes
Dirk

Hi!

What material should collection storage rubber seals are of?
They should be archival quality, non-acid off-gassing.
