[Nhcoll-l] Tips for tiny jars?

[Shoobs, Nate]

Hey Claire,
What is the type of closure?
If you’re topping off that frequently chances are the lids you’re using are bad. If you use vials/jars made from phenolic resin with poly-cone seals, or alternatively polypropylene lids with f217 foam liners, you shouldn’t have to top up narrow-necked containers for years or decades in most cases.

Hi everyone (with apologies for cross-posting),

We have a selection of small specimens in our fluid collection, in jars of around 10 to 25 mL, and they evaporate incredibly quickly. We have to top them up almost annually, which isn't great for the specimens. The rate of evaporation doesn't seem to be worse with a particular fluid, or with a particular sealant.

Do those of you who work with fluid collections have any tips for how to prevent these tiny jars from evaporating so quickly?


Best wishes,
Claire
