DILVAC Low-Profile Stainless Steel-Cased Glass Dewar Flasks

Product Description

DILVAC low-profile Dewar flasks are ideal for use with round bottom reaction vessels or for quick and easy flash-freezing of samples or tempering of stirring rods, pestles and more. These can even be used with magnetic stirrers. These flasks are constructed of double-walled and silvered borosilicate glass which is vacuum pumped before sealing to minimize thermal transfer and ensure a long cryogen holding time. Each glass component is wrapped in a corrosion-resistant stainless steel case to resist damage.

We also offer cylindrical storage/trap Dewars in sizes from 1 to 10 liters in either an attractive blue metal shell (item # 25000) or stainless steel (item # 25001).
