Dewar bottle
The Dewar bottle is a small pressure vessel that is operated airtight to provide good natural ventilation during use. Prevent leakage of gas into the workplace air. Handle lightly, prevent breakage of cylinders and accessories, and equip emergency treatment equipment for leaks.

Argon is a colourless, odourless, non-toxic, non-combustible, high-pressure gas stored in cylinders. When its content increases resulting in an oxygen content below 19.5% it may cause asphyxiation and requires a self-absorbing breathing mask. Bottled gas products are filled at high pressure and should be used only after depressurisation. When each cylinder is used to the end of its life, the residual pressure in the cylinder should be kept at 0.5MPa, and the minimum residual pressure should not be lower than 0.25MPa, and the cylinder valve should be closed to ensure the quality of the gas and the safety of its use. When transporting, storing and using bottled gas products, they should be sorted and stacked. It is strictly forbidden to stack combustible gases and flammable gases together, and they should not be near open flames or heat sources.
