Vacuum-Insulated Stainless All-Steel Dewar Flasks
These vacuum-insulated stainless all-steel dewar flasks are made entirely of stainless steel and are designed specifically for those special applications where typical glass dewars can't be used. Lightweight and compact in 6 standard sizes from 0.5 liters to 6 liters capacity, these flasks are designed for low temperature and high temperature applications. All models are supplied without lids. Models SCI1000 to SCI6000 each have a detachable steel handle (SCI500 does not have a handle). These flasks can be used for ultra-low or very high temperature applications. From the storage and transportation of liquid nitrogen (-196°C) to high temperature ovens of +300°C. For use in physics, chemistry and biological applications, cold traps, oil baths, water baths; for the storage or transporting frozen substances; for heat tempering or transporting high temperature objects, for medical study of frozen cells etc. The list of applications is endless.

Stainless Steel Cased Low-Profile Dewars, No Lids or Handles
These dewar flasks can be used with magnetic stirrers and standard boiling flasks up to 2 liters 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. Ideal for quick and easy flash freezing of samples or tempering of stirring rods, pestle and more. These dewar flasks are constructed of double-walled and silvered borosilicate glass. They are vacuum pumped prior to sealing to reduce thermal transfer and to prolong crygenic holding times. To reduce damage, glass components are wrapped in corrosion resistant stainless steel case.
