Description
MST24 behrotest solid glass stopper NS 24 with rounded end is a solid laboratory stopper made from borosilicate glass 3.3 for standard ground-joint glassware. The NS 24 taper matches common flasks, bottles and reaction vessels, allowing a secure mechanical seal during storage, digestion or sample handling. Its solid construction and rounded tip support smooth insertion into the joint and help limit edge chipping under everyday laboratory use. Borosilicate glass 3.3 combines high chemical resistance with good thermal stability, so the stopper is suitable for aqueous media and many organic solvents encountered in analytical and preparative workflows. Supplied as one piece with a gross weight of 0,07 kg and compact outer packaging of about 0,045 m × 0,045 m × 0,055 m, it is easy to stock as a spare or replacement part. This behrotest stopper from manufacturer Behr fits established NS joint systems without adapters and is intended for routine bench and fume-hood work where an inert, durable glass closure is required. Categories such as ground-joint bottles benefit from consistent geometry and reliable sealing performance across repeated open–close cycles.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about MST24 behrotest Solid Glass stopper rounded TIP NS 24
What is this article?
MST24 behrotest Solid Glass stopper rounded TIP NS 24 is the article on this page. Luminix Health distributes Behr 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.
