Dewars

Cryogenic Liquid Nitrogen Dewars

The Taylor-Wharton LD Series cryogenic dewars are designed for storing and dispensing small amounts of liquid nitrogen. The dewar is ruggedly constructed with a ribbed high strength aluminum body. With their modern construction and advanced insulation materials, Taylor-Wharton LD Series liquid nitrogen dewars assure high thermal efficiency. Their super insulation and superior vacuum performance provides maximum holding times at cryogenic temperatures inside the dewar.
