Description
BOLA blind cap inserts GL 25 are solid polytetrafluoroethylene (PTFE) inserts for laboratory screw-cone caps. The insert is placed into a matching replacement screw-cone cap made of ETFE or PPS and locks in place when the assembly is tightened, forming a secure blind closure. The connection can be dismantled again without difficulty for cleaning or component exchange. Cap thread size is GL 25 with a cap bore of 10 mm, so the insert is usable with BOLA caps D 600-12 and D 634-30. Made entirely from chemically resistant PTFE, the part supports inert sealing on vessels and apparatus in analytical and preparative laboratory work. Offered as one piece with a net weight of 0,012 kg, these inserts from manufacturer Bohlender serve as practical spare parts for maintaining sealed GL 25 fittings. The drop-in design keeps closures serviceable while retaining the chemical resistance expected from PTFE laboratory components in routine media handling and apparatus maintenance.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA Plugs for Screw Caps, GL 25 PTFE
What is this article?
BOLA Plugs for Screw Caps, GL 25 PTFE 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.
