Description
BOLA screw caps for GL 14 threads without bore are laboratory closure caps made from thermoplastic polyester (PBTP) with a grippy knurled exterior and an internal PTFE/silicone gasket. The gasket compensates for unevenness on the sealing face and, once the cap is screwed on, the medium comes into contact only with PTFE by design. This arrangement combines a robust PBTP body with an inert PTFE contact surface for chemical laboratory bottles and small GL-thread vessels. The closed design without a bore is intended for straightforward sealing rather than tubing or probe feed-throughs. Suitable for GL 14 necks commonly found on smaller laboratory glassware, the caps support sample storage, reagent handling and general bench work where a reliable seal is required. Each unit has a net weight of 0,001 kg and is supplied in a pack of 10 pieces for convenient stock on the laboratory shelf. These BOLA closures from manufacturer Bohlender are aimed at research and routine laboratory environments that specify PTFE-wetted sealing on GL 14 containers. The knurled grip aids secure tightening and removal during daily use.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA Screw Caps, GL 14 made of PBTP, without bore
What is this article?
BOLA Screw Caps, GL 14 made of PBTP, without bore 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.
