European specialist in vacuum insulation, KGW Isotherm designs glass and stainless-steel Dewar vessels, cryogenic containers and cold traps for R&D, quality control and production. From sample storage in liquid nitrogen (LN2) to stable-temperature baths, the brand delivers thermal precision, safety and durability. Its vacuum expertise ensures a low boil-off rate, outstanding mechanical strength and ergonomics tailored to the lab bench. Dutscher stocks the key models for life science, chemistry and analytical laboratories.

A well-established specialist in vacuum insulation

Rooted in the tradition of scientific glassware and vacuum technology, KGW Isotherm has made precision isothermy its area of expertise. Over the years, its portfolio has crystallised around silvered glass Dewars for benchtop use and double-walled stainless-steel vessels for demanding cryogenic applications. Working closely with academic and industrial labs, the brand has refined geometries (low/tall form, wide neck), protective coatings and accessories to boost durability and safety. Controlled manufacturing, rigorous quality control and reference-level traceability have steadily established KGW Isotherm as a trusted partner to European laboratories.

Expertise and Areas of Specialisation

KGW Isotherm’s core competence is vacuum expertise applied to thermally stable vessels. Their silvered borosilicate glass Dewars (low or tall form, narrow-neck or wide-neck) provide excellent thermal retention for sample preparation, chilled baths or LN2 holding. Safety coatings, protective metal jackets, insulating lids and carry handles enhance day-to-day safety.

For more demanding operations, double-walled stainless-steel vessels offer robustness, low boil-off rates and safe handling of cryogens. Available in multiple capacities, they are suitable for short-term storage, controlled immersion and in-house transport of liquid nitrogen in R&D, QC or production environments.

The brand also offers cold traps and 'finger Dewars' to protect vacuum pumps and capture solvents during evaporations and distillations. Optimised geometries, silvered surfaces and dedicated accessories improve condensation efficiency, process cleanliness and analytical repeatability.

Overall, KGW Isotherm stands out for predictable thermal performance, a meticulous finish and refined bench ergonomics. Dutscher selects the most relevant references for life sciences, chemistry and analytical applications: appropriate volumes, practical neck designs, compatible accessories and a safety level aligned with the demands of modern laboratories.
