Description
BOLA screw caps GL 45 without bore are black laboratory screw closures fitted with an internal PTFE-silicone seal for GL threads. A knurled PPS body provides a firm grip, and the PTFE/silicone gasket inside helps even out irregularities on the sealing surface. When screwed on, the medium contacts only PTFE by construction, so the process fluid sees the fluoropolymer face rather than the outer cap material. These closed caps without bore are dimensioned for GL 45 threads and support sealed closure of larger laboratory bottles and vessels. Net weight is 0,038 kg per cap. Available in packs of 5 pieces from manufacturer Bohlender, the BOLA screw caps pair a PTFE-wetted seal with a durable PPS housing for everyday laboratory use. The knurled exterior aids controlled hand tightening where a solid, bore-free GL 45 closure with PTFE-silicone sealing is needed.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA Screw Caps, GL 45 without bore, black, with PTFE-Silicone gasket, max. temp
What is this article?
BOLA Screw Caps, GL 45 without bore, black, with PTFE-Silicone gasket, max. temp is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
