Description
The hexagonal glass stopper, borosilicate, clear, NS 24/29 is a hollow glass stopper produced from heat-resistant, durable borosilicate glass according to DIN standard 12252. A hexagonal flat head keeps the stopper from rolling on the laboratory bench and lowers the chance of breakage. The tapered, round-shaped stopper incorporates a drip tip at the lower end so that adhering liquid returns to the flask. Supplied clear for NS 24/29 ground joints, it is packed in units of 10 pieces. Made by manufacturer ISOLAB Laborgeräte, this stopper offers dependable closure for flasks and glassware fitted with the corresponding standard joint. Hollow construction limits weight while borosilicate glass provides the thermal durability expected in laboratory use. Clear glass enables easy visual monitoring of the sealed joint. The stoppers are suited to routine sealing applications in research, analytical and teaching laboratories that require secure fit, effective liquid return and protection against rolling damage on the work surface.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper - glass - clear - hexagonal - 24/29
What is this article?
stopper - glass - clear - hexagonal - 24/29 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.
