Description
BOLA blind cap inserts GL 32 are solid polytetrafluoroethylene (PTFE) inserts intended for laboratory screw-cone caps. Each insert is laid into a matching replacement screw-cone cap of ETFE or PPS and locks securely once the assembly is tightened, creating a reliable blind closure. The joint can be opened again easily whenever cleaning or part exchange is required. Cap thread size is GL 32 with a cap bore of 16 mm, and the insert is usable with BOLA cap D 634-44. Manufactured completely from chemically resistant PTFE, the component supports inert sealing on vessels and apparatus used in analytical and preparative laboratory workflows. Supplied as a single piece with a net weight of 0,024 kg, these inserts from manufacturer Bohlender provide a practical spare for maintaining sealed GL 32 connections. Their simple drop-in construction helps laboratories keep critical closures serviceable while preserving the chemical resistance expected from PTFE laboratory fittings during routine media handling and apparatus care.

Questions about BOLA Plugs for Screw Caps, GL 32 PTFE
What is this article?
BOLA Plugs for Screw Caps, GL 32 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.
