CNDT LHe Research Dewars with detachable bottom flanges
Overview
Designed with SuperVariTemp inserts or immersion inserts in mind, these dewars have demountable bottom flanges allowing easy installation of the desired tail set. They have a completely enclosed liquid nitrogen reservoir for increased cryogen efficiency, and are available in sizes ranging from those suitable for small variable temperature inserts up to those accommodating large diameter superconducting magnets.
Standard Configuration
These dewars have detachable bottom flanges, such that various tail designs can be attached to the same dewar body. The Janis "SuperVariTemp," "VariTemp" or simple immersion tails are usually supplied with this series. Optical or non-optical experiments at low temperatures can be performed with these dewars.
