Description
Reagent bottle 250 ml PP narrow neck is a steep-shoulder laboratory bottle for storing and dispensing reagents and solutions in routine lab work. Made from polypropylene (PP), it offers a lightweight yet robust vessel with good chemical resistance for many aqueous media and common laboratory reagents. The narrow-neck geometry supports controlled pouring and helps limit evaporation during short- to medium-term storage, while the matching PP stopper with joint size NS 19/26 closes the bottle securely for bench use and internal transport. Supplied as one piece with a net weight of 0,042 kg, the bottle stands stably thanks to its steep-shoulder profile and fits efficiently on shelves and in cabinets. This design from manufacturer Witeg suits research, quality-control, and teaching laboratories that need durable plastic reagent bottles with a standardised stopper interface. Use it for sample aliquots, buffer stocks, and general reagent organisation wherever polypropylene containers are preferred over glass.
This article is part of Laboratory glass bottles, in Bottles & containers.

Questions about Reagent bottles 250 ml PP narrow neck
What is this article?
Reagent bottles 250 ml PP narrow neck 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.
