Description
Screw cap, closed, PBT, with silicone PTFE seal, GL 32, red is a robust laboratory closure for GL-threaded bottles and glassware. The closed design is moulded from polybutylene terephthalate (PBT) and fitted with a silicone PTFE seal to deliver a dependable barrier on GL 32 necks. Short-term thermal load capacity of up to 200 °C supports use in heated processes, drying steps, and other elevated-temperature laboratory operations. Offered as one piece per unit, the red cap matches common GL 32 reagent and media bottles used in chemical, pharmaceutical, and life-science laboratories. PBT provides good mechanical strength and form stability, while the silicone PTFE gasket promotes consistent sealing during storage, handling, and moderate thermal stress. From manufacturer lab-o-plastix, this closed GL 32 screw cap is suited to routine sealing tasks where chemical compatibility and secure thread engagement matter. It integrates cleanly into standard bottle systems for solvents, buffers, and process solutions without adding bulk or complexity to the closure assembly.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, closed, made of PBT, with silicone PTFE seal, GL 32, red
What is this article?
Screw cap, closed, made of PBT, with silicone PTFE seal, GL 32, red is the article on this page. Luminix Health distributes lab-o-plastix 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.
