Foam Cryo Dewars are lightweight, durable alternatives to glass-lined dewars. The material is robust and will not develop leaks or degrade over time, nor will it shatter if dropped like a glass-lined dewar. The low thermal mass results in less liquid nitrogen boiling off and the foam surface accumulates less frost, resulting in less liquid nitrogen is consumption.
Pope Dewars are ideal for temporary storage of liquid nitrogen in laboratory settings.
These dewars are the lab standard in glass lined, fully silvered dewars. They are readily
available in a variety of standard shapes and numerous sizes. We have cylindrical, narrow-mouth,
hemispherical, along with convenient low-form shallow styles. Extended base and handle versions
are also available.
Low Form Shallow Open Top Dewars in cylindrical and hemispherical configurations are available
in popular sizes to match standard flask sizes. Fully silvered glass dewars are based with
tip-offs off center for use with stirrers.
The traditional Lab Grade Dewar line encompasses a full range of sizes of fully silvered, glass
double-walled evacuated flasks. The wide mouth cylindrical dewar is available with a choice of
either protective mesh or extended aluminum housing and also the popular narrow mouth spherical
configuration. Lab grade dewars for benchtop use come with polyethylene lids.
Handled Lab Grade Dewars offer a complete lab grade dewar at an affordable price. The most popular
wide mouth cylindrical Dewars are manufactured with a full extended aluminum base, full exposed lip
and attached handle to facilitate portability, safety and convenience. |
