Dewar flasks

DURAN^®. DIN EN ISO 16496. Cylindrical. With blue coated protective casing made of metal. All vessels can also be supplied without casing, unsilvered or silvered with opposite viewing strips. Stoppers - please order separately.

DURAN^®. DIN EN ISO 16496. Cylindrical design with insulated lid, held by two spring clips and aluminium carrying handle. For cooling, storage and transport of small samples of temperature-sensitive goods e.g. with liquid nitrogen (LN₂) or dry ice (CO₂). When storing liquid nitrogen (LN₂) or CO₂ a hole (diam. approx. 2 mm) in centre of the lid is necessary that no overpressure can arise in the vessel.
