DILVAC Stainless Steel-Cased Glass Dewar Flasks

Item #: 25001
Quantity:
$420.00

Availability: 1-2 business days

Product Description

DILVAC Dewar flasks are for the storage and transport of liquified gases such as nitrogen or helium as well as Dry Ice. 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, and comes with a bail-style handle for easy carrying. Each also includes an insulated vented lid which can be secured with the included lid clamp to minimize spillage of the contents during transport while ensuring the pressure release necessary with such systems.

Typical applications include transport of cryogens as well as cooling traps on Schlenk and high-vacuum manifolds. We also offer the same flasks but with a with an attractive blue metal shell (item # 25000) as well as a lineup of low-profile Dewars which are ideal for reaction vessels such as round-bottom flasks (item # 25002).

These Dewars are available in three separate sizes:
