Description
Screw cap, 12 mm, blue, with O-ring is a laboratory screw closure with an integrated O-ring, made for catalogue numbers 716XXX, 717XXX and 722XXX. The 12 mm cap is finished in blue so that closures can be distinguished by colour during sample handling. An O-ring is part of the cap assembly for use on the corresponding vessels in those catalogue families. The product is packed as 500 pieces, with 5000 pieces per carton, which supports bulk laboratory stocking of screw caps. Available from manufacturer Greiner Bio-One, it originates in Slovakia. Laboratories should fit this blue 12 mm screw cap to the named 716XXX, 717XXX and 722XXX catalogue series rather than to unrelated containers. Blue colour coding is a practical way to mark a sample group or process step when several 12 mm O-ring caps are used side by side. Choose this blue variant when a matching blue screw closure is required for those catalogue numbers and when carton quantities of 5000 pieces are convenient for the laboratory store.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, 12 MM, blue, with O-ring, for kat.
What is this article?
Screw cap, 12 MM, blue, with O-ring, for kat. is the article on this page. Luminix Health distributes Greiner Bio-One 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.
