Description
Reagent bottle 250 ml narrow neck amber glass with PE stopper is a laboratory storage vessel for reagents and solutions. It offers a nominal volume of 0,25 l with ground joint NS 19/26 and a narrow-neck (Enghals) design that supports controlled pouring and standard joint connections. The body is soda-lime glass in amber brown, helping shield light-sensitive contents from visible light during storage and handling. A polyethylene (PE) stopper provides a practical closure for everyday laboratory use. Net weight is 0,227 kg per bottle. These steep-shoulder reagent bottles from manufacturer Witeg suit routine chemical storage, sample handling and reagent preparation in research, quality-control and teaching laboratories. Amber soda-lime glass is a common choice where reduced light exposure is preferred without moving to specialised optical glass. The NS 19/26 joint aligns with widely used laboratory glassware, simplifying integration into existing setups. Supplied in packs of 10 pieces, the format supports consistent stocking of narrow-neck amber bottles for daily workflows with aqueous and many organic laboratory media under normal conditions.

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.
