Description
Plastic stoppers, PE, DIN 12254 with standard ground joint 19/26 are octagonal laboratory stoppers for secure closure of vessels and apparatus fitted with corresponding standard taper joints. Produced from polyethylene (PE), they deliver a durable, lightweight sealing solution for day-to-day laboratory applications where glass stoppers may be less practical. The octagonal head design provides a secure grip, facilitating controlled opening and closing even under gloved conditions. Built to DIN 12254, the 19/26 standard ground joint ensures dimensional fit with common laboratory flasks, bottles and reaction equipment. These stoppers from manufacturer Lenz are packed in units of 10 pieces, supporting efficient replenishment for teaching labs, research teams and analytical environments. With a weight of about 0,008 kg, each stopper remains easy to handle while helping reduce evaporation and contamination risks. They are well suited to general chemistry, biology and quality-control workflows that rely on standard taper glassware for sample and reagent containment.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Plastic stoppers, PE, DIN 12254, standard ground joint 19/26, octagonal
What is this article?
Plastic stoppers, PE, DIN 12254, standard ground joint 19/26, 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.
