Description
Tamper-evident closures GL45 are red polypropylene sealing caps designed for secure closure of laboratory bottles with a GL 45 thread. Made from polypropylene (PP), these Originalitätsverschlüsse provide a clear visual indication that a bottle has remained unopened, supporting sample integrity and controlled handling in everyday lab workflows. They are intended for use with VITgrip™ bottles and fit the widely used GL 45 neck finish found on many reagent and media containers. Supplied from manufacturer Marienfeld, the closures come packed six pieces per bag, which suits both routine restocking and organised bench-side use. The robust PP construction offers reliable mechanical strength for repeated handling while remaining lightweight and easy to apply. In research, quality control, and general laboratory environments, tamper-evident GL 45 closures help mark sealed containers, reduce the risk of unnoticed opening, and keep bottle necks protected between uses. Their dedicated fit for VITgrip™ bottles makes them a practical accessory wherever standardised GL 45 packaging is employed for liquids, buffers, or other laboratory media.

Questions about Tamper-evident screw caps GL45,
What is this article?
Tamper-evident screw caps GL45, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Bouchons à vis & fermetures, inside Bouchons, capuchons & fermetures, in Matériel de laboratoire.
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.
