Dewar Flask

--

Micro Filtertaion Assembly

JN SCIENCETECH Dewar flasks are designed to be tough and robust, and all are rust-free, non-corrosive and hygienic. All our Dewar Flasks models incorporate double-walled boroscilicate 3.3 glass, which is vacuum-pumped for the efficient storage, transport and use of liquid nitrogen and dry-ice. We offer a number of types of vacuum flask, from an economy range to a standard stainless steel range and an innovative range of wide-necked, shallow glass Dewars. Our wide-necked Dewar flasks are particularly popular in many laboratory applications as the shallow form allows for the minimum amount of coolant to be used.


Micro Filtertaion Assembly

Our dewar flasks can be used with magnetic stirrers and standard boiling flasks up to 600ml in capacity. Also ideal for rapid/flash freezing, tempering of stirring rods, pestles, etc. The shallow style allows for minimum amount of coolant to be used.


Micro Filtertaion Assembly

Our dewar flasks are rust-free, non-corrosive, hygenic and strong. Double-walled boroscilicate glass, vacuum pumped and silvered insures efficient storage, transport and use of liquid nitrogen and dry-ice. These Dewar Flasks have an all-stainless steel vented lid with self-contained insulation. Lid-clamps secure the lid for safe transportation and minimizing spillage.
