Description
Screw caps made of urea resin moulding compound black, with insert made of Lupolen® GL 40, provide secure closure solutions for laboratory bottles and vessels. These black screw caps utilise a durable urea resin moulding compound body paired with a Lupolen® GL 40 insert to achieve reliable sealing. Supplied in a pack size of 1 pc and offered across different packing units, they suit varied laboratory workflows. The black colour delivers a uniform professional finish while the specialised insert supports consistent contact with container necks. Suitable for general laboratory sealing tasks, sample protection and routine handling, the design aligns with standard screw-cap and originality-closure requirements. These components from manufacturer Hecht integrate straightforwardly into existing glass or plastic bottle systems without complex adaptation. The combination of moulded urea resin and Lupolen® GL 40 insert yields practical mechanical stability for repeated opening and closing cycles in research, quality-control and storage environments. Different packing units allow flexible stock management according to laboratory scale and consumption patterns.

Questions about Screw caps of urea resin molding compound, black, sealing of Lupolen® GL 40
What is this article?
Screw caps of urea resin molding compound, black, sealing of Lupolen® GL 40 is the article on this page. Luminix Health distributes Hecht 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.
