Description
Steep-shoulder bottles 250 ml with narrow neck are clear soda-lime glass reagent bottles designed for laboratory storage and handling of liquids. Each bottle features a ground joint NS 19/26 and is supplied with a matching PE stopper for a secure, practical closure. The steep-shoulder form and enghals (narrow-neck) geometry support controlled pouring and reduced evaporation risk during routine work. Nominal volume is 0,25 l, with a net weight of 0,218 kg per bottle. Clear glass allows easy visual inspection of contents and fill level. These bottles belong to the classic ground-joint bottle category used for reagents, solvents and sample aliquots in analytical and preparative laboratories. Manufactured by Witeg from soda-lime glass, they offer a robust, transparent vessel suited to everyday lab workflows. Supplied in packs of 10 pieces, they provide a convenient stock unit for teaching labs, quality-control benches and research groups that require standardised narrow-neck glassware with PE stoppers.

Questions about Bottles conical shoulder, narrow mouth,
What is this article?
Bottles conical shoulder, narrow mouth, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Plastic bottles (narrow & wide mouth), inside Bottles & containers, in Labware.
A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
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.
