Description
Caps for reaction vials in red are laboratory closures intended for use with reaction vials in molecular biology, microbiology and cell culture settings. These red caps enable straightforward colour coding of samples, reagents or process batches when working with cryogenic tubes and screw-in vessels. Each pack contains 1000 pieces and has a total weight of 0,500 kg, offering a convenient supply for busy laboratory benches and shared equipment rooms. Visual differentiation through colour supports efficient sample tracking during storage, incubation and transport steps typical of molecular biology workflows. The caps form part of the ROTH SELECTION assortment and are positioned for routine labware use alongside compatible tubes and vessels. Laboratories handling multiple parallel series of reactions benefit from dedicated colour sets that keep workflows organised without relying solely on labels. Suitable for research groups, quality-control units and teaching laboratories, the red caps help maintain clear separation of sample groups throughout daily experimental procedures. Consistent pack presentation and colour identity make reordering and stock management straightforward for laboratory managers.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Caps for reaction vials, red, 1000 unit(s)
What is this article?
Caps for reaction vials, red, 1000 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
