Description
Steep-shoulder bottle, narrow neck, is a 250 ml polypropylene bottle closed with a ground stopper NS 19/26 for laboratory storage where a jointed seal is preferred over a screw cap. The Enghals narrow-neck design and steep-shoulder body give a compact footprint while the NS 19/26 stopper interface supports secure seating typical of ground-joint glassware practice, here realised in polypropylene (PP). Nominal volume is 0,25 l, making the bottle suitable for reagents, intermediates, and samples handled in standard bench volumes. Supplied in packs of 20 pieces, it offers a practical stock unit for teaching labs, preparative work, and general chemical logistics. This steep-shoulder bottle from manufacturer Vitlab combines plastic durability with a defined conical joint size for users who standardise on NS 19/26 stoppers. The PP construction keeps the vessel lightweight compared with glass alternatives of similar capacity, while the jointed stopper format aids alignment and repeated opening and closing. Clear association with Schliff bottle categories helps selection alongside other ground-joint accessories. Appropriate for laboratories needing narrow-neck PP bottles with NS 19/26 closure in the 250 ml range for organised storage and handling.

What is this article?
Narrow-neck bottle, PP, with stopper, 250 ml, NS 19/26, conical shoulders is the article on this page. Luminix Health distributes Vitlab 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.
