Description
Screw cap with seal GL14 is a replacement screw closure designed for laboratory glassware with a matching GL 14 thread. Each cap is supplied complete with an integrated seal, providing a straightforward spare part for maintaining secure closures on compatible tubes and bottles. Packaged in a unit of 10 pieces and weighing 0,002 kg net per item, these caps support routine laboratory maintenance and inventory replenishment. Manufactured by Witeg, the GL 14 format fits standardised screw threads commonly used on sample and reagent containers. Replacement caps with seal help keep existing glassware in service when original closures become worn or misplaced, reducing downtime in sample preparation and storage workflows. The compact design is intended purely as a functional spare, matching the stated GL 14 geometry without additional fittings. Laboratories handling multiple GL 14 vessels can stock these caps for quick exchange during daily operations, ensuring consistent sealing performance across borosilicate and other compatible laboratory containers that use the same thread standard.

Questions about Spare screw caps with seal, GL 14
What is this article?
Spare screw caps with seal, GL 14 is the article on this page. Luminix Health distributes Witeg 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.
