[Nhcoll-l] Screw caps for fluid preservation

[Dirk Neumann]

Hi Joosep,

I would avoid any silicone and especially rubber inlays. If possible, prefer PE inlays.

Also, I am not sure if these Macherey & Nagel vials are designed for long term storage, or for lab use. When in Munich, I inherited different research collections with such lids - and they were mostly deteriorated.

Better choose pharmaceutical glassware like those wide-neck jars, e.g. from gerresheimer; these are distributed by many resellers

Hope this helps
Dirk

Dear all,

We are looking for screw caps for vials in fluid perservation collection but there are many choices that are possible to order. Can somebody please suggest which of them are the best for fluid specimen vials?
