Description
Screw cap, 12 mm, green, with O-ring is a 12 mm laboratory screw closure supplied with an O-ring and designated for catalogue numbers 716XXX, 717XXX and 722XXX. Green colouring of the cap supports visual identification next to other cap colours in the same diameter. The O-ring is included with the screw cap for the compatible openings of those catalogue families. Packaging comprises 500 pieces and 5000 pieces per carton for ongoing laboratory demand. The closure is from manufacturer Greiner Bio-One and the country of origin is Slovakia. It is a dedicated green 12 mm screw cap for the 716XXX, 717XXX and 722XXX series, not a universal stopper for other formats. In laboratory workflows, green O-ring screw caps help separate sample batches when red, blue and green closures are used together. Specify this green variant where a 12 mm green screw cap with O-ring is required for the listed catalogue numbers and where 5000 pieces per carton meet stock-holding needs.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap, 12 MM, green, with O-ring, for kat.
What is this article?
Screw cap, 12 MM, green, 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.
