Description
Aspirator bottle 500 ml NS 19 is a laboratory glassware vessel for controlled liquid dispensing, clarification and temporary storage of aqueous and many organic media. Fabricated from borosilicate glass 3.3, it provides a nominal volume of 0,5 l, a height of 165 mm and an outer diameter of 89 mm, offering a compact yet practical bench footprint. The neck is ground to NS 19/26, and a lateral tubulature is likewise finished NS 19/26 so that stopcocks, adapters or tubing can be connected securely. A stopcock bore of 4 mm supports steady, controllable outflow during aspiration or gravity-fed transfer. Conforming to DIN 12037, this aspirator bottle from manufacturer Witeg combines the chemical resistance and thermal durability of borosilicate 3.3 glass with standardised joint geometry familiar in European laboratories. Supplied as 1 pc, it suits filtration setups, sedimentation work, reagent reservoirs and general wet-chemistry procedures that require transparent, robust glassware with defined ground joints and reliable flow control.

Questions about Aspirator bottles, borosilicate glass, 5
What is this article?
Aspirator bottles, borosilicate glass, 5 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Canisters & jerrycans, inside Bottles & containers, in Labware.
A canister or jerrycan holds litres, not millilitres, and it is shaped to be carried and to pour. The material has to survive the liquid for the whole time the can sits in the store.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
