Description
BOLA grooved sleeves NS 45/40 PTFE are ground-joint sealing sleeves for laboratory glassware connections. Made entirely of polytetrafluoroethylene (PTFE), they carry sealing rings on the outer surface that remain easy to reach and clean after use. The profile has no protruding grip collar, so standard joint clamps can be fitted without obstruction. Rated for vacuum service down to 0,1 mbar, the robust construction is intended for continuous laboratory duty. Dimensions follow the European standard size NS 45/40. Offered as a pack of 5 pieces with a net weight of 0,001 kg, these sleeves suit assemblies that need the chemical resistance and dimensional stability of PTFE. The BOLA design from manufacturer Bohlender keeps the sealing elements accessible while preserving full clamp compatibility on conical joints. Typical applications include distillation trains, synthesis apparatus and general vacuum glassware where a reliable, cleanable PTFE interface between ground joints is required without compromising mechanical retention of the connection.

Questions about BOLA Sleeves with Ribs, NS 45/40 PTFE
What is this article?
BOLA Sleeves with Ribs, NS 45/40 PTFE 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.
