Description
Test tubes 125 x 16 mm are precision laboratory glassware produced from borosilicate glass 5.1 for reliable chemical resistance and thermal stability. Each tube measures 125 mm in length and 16 mm in diameter, with a uniform wall thickness of 1,0-1,1 mm and a round bottom that supports even heating and secure standing in standard racks. A white frosted writing area allows clear sample labelling, while the integrated 15-415 thread accepts the supplied black screw cap fitted with a Butyl/PTFE seal for leak-resistant closure. These tubes are sterilizable up to 110 °C, making them suitable for sample preparation, storage, incubation and general analytical work in research, quality-control and teaching laboratories. Packed as 100 pieces per carton from manufacturer Marienfeld, the set provides a practical stock of durable, reusable glass tubes that integrate easily into everyday laboratory workflows requiring consistent dimensions and secure sealing.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Test tubes 125x16 mm,
What is this article?
Test tubes 125x16 mm, is the article on this page. Luminix Health distributes Marienfeld 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.
