Dewars
DILVAC Dewar 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 metal case to prevent damage and assure years of corrosion-resistance operation.
Choose from tall form cylindrical Dewars that are ideal for use with vacuum traps on most common Schlenk and high-vacuum manifolds, or low-profile Dewars which are idea for round-bottom flasks, flash-freezing, and other benchtop cryogenic operations.
