Description
Caps for reaction vials are yellow closures intended to seal matching reaction vials used in molecular biology, microbiology and cell-culture laboratories. The coloured caps help with quick visual identification of samples, series or process steps when several tubes are handled in parallel. They form part of the labware assortment for tubes used in molecular biology and related cryogenic or screw-in vessel applications. Supplied as 1000 pc(s) per pack, the yellow caps provide a bulk quantity suitable for high-throughput benches and shared laboratory stocks. The pack weight is given as 0,500 kg. These caps from manufacturer ROTH SELECTION are designed as dedicated accessories for reaction vials, supporting secure closure during mixing, short-term storage or transport within the laboratory. Consistent yellow colouring aids organisation and reduces mix-ups in multi-sample workflows, while the large pack size keeps consumable supply aligned with frequent vial use in routine molecular and cell-culture work.
This article is part of Microcentrifuge & reaction tubes, in Microplates, PCR & reaction tubes.

Questions about Caps for reaction vials, yellow, 1000 unit(s)
What is this article?
Caps for reaction vials, yellow, 1000 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Microcentrifuge & reaction tubes, inside Microplates, PCR & reaction tubes, in Lab consumables.
A microcentrifuge tube, the familiar 1.5 mL or 2 mL flip-cap tube, holds a small reaction or a spin-down. The cap style, the centrifugal-force rating and whether the tube is low-binding are the specification. A PCR tube is thinner and is a different article.
A microplate is an array of wells so the same step can be done many times. A deep-well plate holds more volume. A PCR plate or a strip of tubes is thin-walled so the temperature of a cycler reaches the liquid quickly. A seal keeps the well from evaporating. The well number, the working volume and whether the plate is skirted for a robot are the choices. Diagnostic test systems are listed under ISO in vitro diagnostic systems. Methods are on PubMed.
