KGW cylindrical Dewar vessels with handle
KGW cylindrical Dewar vessels with handle are specially designed containers for the safe storage and smooth transport of cryogenic liquids such as liquid nitrogen (LN?). They are characterised by their robust construction, high material quality and well-thought-out handling. Anyone who relies on reliable Dewars in laboratories, research facilities or industrial production environments will find this product to be a first-class solution that guarantees both durability and a high level of safety. Compared to similar products on the market, they score points above all for their solid metal casing, low weight and extremely long service life when handling cryogenic media.
Reliable design and performance features
The cylindrical Dewar vessels are based on robust borosilicate glass 3.3, which is embedded in a blue-coated metal shell. This combination of materials ensures perfect insulation from environmental influences, keeping the evaporation rate within a low range. At the same time, the metal shell provides efficient protection against mechanical influences during internal transport. The integrated handle is particularly practical, ensuring comfortable handling.
Another significant advantage of these Dewars is their flexible volumes ranging from 200 ml to 8,000 ml, ensuring that the right size is available for a wide variety of applications. The product range includes designs with varying heights and diameters, allowing users to choose a model that exactly meets their requirements. The lightweight design allows for easy handling, even when the vessel is filled with liquids such as LN?. In addition, long service lives ensure efficient use: for example, some models achieve an LN? service life of up to 220 hours, which is a major advantage in complex laboratory environments or for longer transport routes.
Important technical data at a glance:
- Volume: 200 ml to 8000 ml
- Material: borosilicate glass with protective metal shell
- Height: 215 mm to 660 mm (depending on model)
- Diameter (external): 63 mm to 165 mm
- Weight: 0.3 kg to 4.6 kg

- LN? evaporation rate: between 0.2 L/d and 1.2 L/d
In addition, the ergonomically shaped handle makes transport particularly safe. For laboratory and production areas where frequent relocation and stable storage are required, these Dewar vessels offer an ideal combination of handling, stability and service life.
Certifications and standards
Certifications and standards play a central role in the storage and transport of cryogenic substances in order to ensure the highest safety and quality standards. These vessels comply with the relevant specifications for the safe handling of liquid nitrogen and comparable substances. The impact-resistant protective housing and the acid- and water-resistant design underline the high quality standards. Especially in areas where DIN or CE conformity is required, this design ensures that all regulations for handling hazardous substances are met.
Application examples
These Dewar vessels are used in a wide range of industries. Wherever sensitive samples, reagents or materials need to be stored at extremely low temperatures, reliable storage solutions are essential:
- Biology and medical research centres: storage of cell cultures, enzymes or proteins that only retain their desired stability in liquid nitrogen. - Pharmaceutical and vaccine production: storage of cryogenic media, for example for special production steps or testing of novel active ingredients.
- Chemical industry: Provision of liquids such as LN?, liquid oxygen (LOX) or other cryogenic reaction components for synthesis.
- Food technology: Cooling and freezing of various ingredients or samples to preserve their quality and composition for analysis purposes.
FAQs
How high is the risk of accidents during handling?
The design minimises risks, as stable handles and robust outer shells offer safe handling and reliable protection. If general laboratory and hazardous substance guidelines are observed, the risk of accidents remains extremely low.
Which liquids are suitable for use?
Cryogenic liquids such as LN? or LOX in particular can be stored and transported without any problems. They can also be used with various laboratory chemicals, provided that their specific temperature and material requirements are met.
How easy is it to clean?
The smooth surfaces and robust metal housing make cleaning easy. Residues can be removed with mild cleaning agents and clear water.
Can different sizes be used in parallel?
Yes, laboratories and production areas often require several vessels of different sizes. The design allows for easy integration alongside other storage and process systems.
