Description
BOLA Grip Collar Sleeves NS 100/60 are reusable laboratory sleeves made from polytetrafluoroethylene (PTFE) for sealing standard ground joints in scientific glassware. They feature a protruding grip collar and external sealing rings that deliver a high-vacuum-tight seal with a low leak rate below 0,0001 mbar × l/s. The robust construction is intended for continuous use, while the sealing rings stay easy to clean because they remain readily accessible. Dimensions follow the European standard size NS 100/60. Each unit is supplied as one piece with a net weight of 0,035 kg. These sleeves support reliable joint sealing in vacuum apparatus and glassware assemblies where chemical inertness and mechanical durability are required for everyday laboratory workflows. From manufacturer Bohlender, the BOLA design combines practical handling via the grip collar with consistent sealing performance across repeated assembly and disassembly cycles. Laboratory users can apply them on ground-joint connections that need low leakage, PTFE chemical resistance, and straightforward maintenance without disposable liners.

Questions about BOLA Sleeves with Gripping Ring, NS 100/60 PTFE, reusable
What is this article?
BOLA Sleeves with Gripping Ring, NS 100/60 PTFE, reusable is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Labware.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
