Description
Tamper-evident cap, 28 mm, ROPP with spout is a polypropylene closure engineered for PET narrow-mouth bottles in laboratory and sample-handling use. The roll-on pilfer-proof (ROPP) construction delivers a clear tamper-evident feature, while the integrated spout supports controlled pouring or dispensing from the bottle. Made of PP, the cap is suited to everyday lab packaging tasks where a resealable, pour-friendly finish on PET containers is preferred. The pack comprises 10 pieces with an approximate weight of 0,060 kg, convenient for stocking at the bench or in small production runs. The 28 mm neck size aligns with standard PET narrow-mouth bottles, ensuring straightforward pairing within common labware ranges. Available from manufacturer SEMADENI, these caps serve laboratories, pilot facilities and preparation areas that require secure, tamper-evident closures with an integral spout. They fit into existing plastic-bottle workflows and help standardise finishing of PET vessels used for reagents, buffers or samples. Explicit material, diameter and spout details aid quick selection next to matching PET narrow-mouth bottles.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Tamper-evident cap, 28 mm, ROPP,, PP w. spout, f. PET narrow mouth bottles
What is this article?
Tamper-evident cap, 28 mm, ROPP,, PP w. spout, f. PET narrow mouth bottles is the article on this page. Luminix Health distributes SEMADENI 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.
