Description
Plastic stopper PP, NS 19/26 is a polyethylene stopper for standard ground joints, made to seal NS connections on laboratory glassware securely. It provides a practical plastic closure for flasks, receivers and other jointed apparatus used in synthesis, distillation and general wet chemistry. A hexagonal flat head stops the piece rolling off the work surface, while the hollow head collects retained liquid and reduces the risk of bench damage from drips. Supplied in packs of 10 pieces from manufacturer ISOLAB Laborgeräte, the NS 19/26 size fits a common larger joint standard found on many reaction vessels and multi-piece set-ups. Non-sterile construction makes these stoppers suitable for everyday laboratory use where sterility is not required. They offer a lightweight, easy-to-handle alternative to glass stoppers and support clean, reliable sealing across standard Normschliff glassware in teaching, industrial and research laboratories.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper - P.E - 19/26
What is this article?
stopper - P.E - 19/26 is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
