Low Form Dewars
Pope Low Form Shallow Dewars
no. 81740-10 to 81740-40

Description

Low Form Dewars

Pope Low Form Shallow Dewars (open design, no lid) permit essential operations not practical with standard cylindrical or spherical dewars.

These operations include:

  • Rapid freezing and recovery of tissue/organ specimens
  • Insertion of small flasks in dewar
  • Agitation in flask with magnetic stirrer
  • Tempering of stirring rods, pestles and other small objects

 
The protective aluminum bases on both styles extend the full height of the dewars.
Note that protected vacuum tip-off tubulations are offset to the side to minimize space between the dewar bottoms and magnetic stirrers.

The hemispherical line has been expanded to provide additional dewars to fit larger flask sizes.

Economies in coolant use will be realized in all operations where Pope Low Form Shallow Dewars are more practical.
Cooling range from dry ice/acetone to liquid nitrogen.

Pope Low Form Shallow Dewars are available in several sizes and two configurations, hemispherical and cylindrical (with semi-flat bottom).
The cylindrical configuration increases coolant capacity.

Holding time 2-6 hours depending on volume.
