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.
DILVAC low-profile Dewars are available in five separate sizes:
