Description
Screw cap, LDPE, natural, GL 28 is a low-density polyethylene laboratory closure intended for bottles and containers fitted with a GL 28 thread. Produced from polyethylen niedrige Dichte (LDPE) in a natural finish, the cap offers a flexible polymer sealing solution for general laboratory use where soft, chemically familiar plastics are preferred for everyday closures. The GL 28 thread supports secure engagement with matching laboratory bottles used for reagents, media components, wash solutions and intermediate samples in analytical, preparative and teaching settings. Supplied as one piece, this natural LDPE screw cap from manufacturer lab-o-plastix integrates easily into standard glassware and plasticware systems that follow the GL thread convention. Its unpigmented appearance helps visual distinction of contents and labelling on the bottle neck area during routine workflow. Suitable for collections of screw closures and original-seal accessories, the product addresses simple, reliable capping needs without additional decorative colouring. Laboratories organising multi-size GL inventories can use this GL 28 natural LDPE variant alongside related closures to maintain consistent thread standards across storage and handling steps.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, LDPE, natural, GL 28
What is this article?
Screw cap, LDPE, natural, GL 28 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.
