Description
Narrow-mouth steep-shoulder bottle 50 ml is a clear soda-lime glass laboratory bottle fitted with an NS 14/15 ground joint and matching NS glass stopper. The 50 ml nominal volume (0,05 l) and narrow-neck design support controlled storage, dispensing and short- to medium-term holding of reagents, standards and intermediate solutions on the bench. Clear glass allows direct visual inspection of contents and fill level, while the ground-joint stopper provides a reliable closure for routine laboratory use. The steep-shoulder form is a classic bottle geometry that sits stably, pours cleanly and fits standard racks and storage trays. With a net weight of 0,08 kg, each bottle remains easy to handle during weighing, labelling and transfer steps. Supplied in packs of 48 pieces from manufacturer Witeg, these bottles suit teaching laboratories, analytical workflows and general chemical organisation where soda-lime glass with standardised NS closures is appropriate. They help keep small-volume reagents orderly and ready for daily experimental work.

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.
