Description
Closure without seal PP28, black is a laboratory bottle cap for PP28 neck finishes, supplied without an integrated sealing insert. It is designed for glass bottles with article numbers FRAN and FRAA, PET bottles FPET and FPTA, and HDPE bottles FRIP. Attention: for FRIP-030-010 bottles only the TP28-X01-020 closures are suitable. This black variant from manufacturer Labbox comes in a practical pack of 20 pieces with a net weight of 0,075 kg, ideal for smaller laboratory stocks, method development or colour-coded bottle sets. Black closures help distinguish contents, hazard classes or process stages at a glance while maintaining a uniform PP28 interface across compatible glass, PET and HDPE containers. They support everyday sample storage, reagent handling and general laboratory workflows that rely on standardised neck finishes. The compact pack size is convenient for bench-side replenishment without committing to bulk quantities, while remaining fully aligned with the listed bottle article ranges.

Questions about Screw cap PP28 with security seal, black, 20 pcs
What is this article?
Screw cap PP28 with security seal, black, 20 pcs is the article on this page. Luminix Health distributes Labbox 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.
