Description
Plastic stoppers made of polyethylene (PE) according to DIN 12254 are octagonal closures intended for standard ground joint 10/19 laboratory glassware. Manufactured from PE, they provide a robust, lightweight seal for flasks and vessels with matching taper joints during routine laboratory storage, handling, and transport. The octagonal design offers a secure grip for easy fitting and removal, including when gloves are worn. DIN 12254 compliance supports interchangeability with widely used European ground-joint systems in research, education, and industrial laboratories. Available as a pack of 10 pieces from manufacturer Lenz, the stoppers help keep multiple glassware setups sealed and ready for use. Pack weight is 0,195 kg, reflecting the larger 10/19 joint size while remaining practical for shelf storage alongside other stoppers and clamps. These PE stoppers suit general laboratory applications with non-aggressive media where a plastic taper stopper is preferred, and they fit naturally into standard ground-joint glassware and consumable workflows.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Plastic stoppers, PE, DIN 12254, standard ground joint 10/19, octagonal
What is this article?
Plastic stoppers, PE, DIN 12254, standard ground joint 10/19, octagonal is the article on this page. Luminix Health distributes Lenz 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.
