Description
Conical ground joint stopper, PE-LD, NS 34/35 is a hollow laboratory stopper with an octagonal profile and sealing rings for closing glassware fitted with standard conical ground joints. Manufactured from low-density polyethylene (LDPE), it is intended for NS 34/35 joints commonly found on flasks, adapters and related apparatus. The hollow body keeps the component lightweight, while the eight-sided grip supports secure handling during insertion and removal. Integrated sealing rings assist contact with the ground joint surface. This plastic stopper from manufacturer Brand is supplied as a single piece and belongs to the range of standard ground-joint and plastic stoppers used in chemical, analytical and teaching laboratories. PE-LD construction provides the flexibility typical of this polymer for routine sealing tasks. With a net weight of 0,012 kg it remains easy to manage in everyday workflows. Suitable for distillation, reaction and storage setups that require a non-glass joint closure of this size.

Questions about Conical joint stopper, PE-LD, NS 34/35 octag. grip hollow seal. rings
What is this article?
Conical joint stopper, PE-LD, NS 34/35 octag. grip hollow seal. rings is the article on this page. Luminix Health distributes Brand 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.
