[NHCOLL-L:3506] supplier for stoppers

[colin favret]

No vial stopper is truly archival, but silicone comes close. The INHS  
insect collection uses TapeCase silicone stoppers. For ease of use,  
durability, and reliability, these are the best patent-lip vial  
stoppers I've seen. You can get a further discount if you get a quote  
and order in bulk.
