Description
BOLA grip collar sleeves NS 14/23 are reusable PTFE ground joint sleeves for sealing laboratory glassware. Made from polytetrafluoroethylene (PTFE), each sleeve has a protruding grip collar and external sealing rings that deliver high-vacuum-tight sealing with a low leak rate below 0,0001 mbar × l/s. The robust design is intended for continuous laboratory use, and the accessible sealing rings are easy to clean between runs. Dimensions follow the European standard joint size NS 14/23, making the sleeves a practical fit for common conical ground joints in synthesis, distillation and vacuum work. Supplied as a single piece with a net weight of 0,0022 kg and a gross weight of 0,003 kg, these reusable sleeves from manufacturer Bohlender provide chemical-resistant joint protection without disposable waste. PTFE construction supports broad chemical compatibility where durable, cleanable ground-joint sealing is required in research and analytical laboratories.

Questions about BOLA Sleeves with Gripping Ring, NS 14/23 PTFE, reusable
What is this article?
BOLA Sleeves with Gripping Ring, NS 14/23 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.
