Description
Screw-on lids with silicone sealing are polypropylene closures intended for secure capping of compatible reaction and cryogenic vials in molecular biology and cell-culture laboratories. Finished in brown and supplied loose, these lids incorporate a silicone sealing element that supports a tight fit against matching vessel rims, helping maintain sample integrity during handling, short-term storage, and transport. The PP construction provides a practical balance of chemical resistance and mechanical durability for everyday labware use. Designed as screw-on accessories within the cryogenic tubes and screw-in vessels category, they complement freestanding or conical reaction vials and related polypropylene tubes used in microbiology workflows. From manufacturer ROTH SELECTION, the lids arrive in a bulk pack of 1000 pieces, suited to high-throughput benches and stock replenishment. Their loose presentation allows flexible dispensing at the workstation without pre-assembled tube sets. These brown screw-on lids with silicone sealing offer a straightforward consumable option for laboratories standardising closures across sample series and routine molecular-biology tube systems.
This article belongs on Molecular biology reagents (other), in Molecular biology.

Questions about Screw-on lids, PP, with silicone sealing, brown, loose, 1000 unit(s)
What is this article?
Screw-on lids, PP, with silicone sealing, brown, loose, 1000 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Molecular biology reagents (other), inside Molecular biology, in Life Science & Microbiology.
These are the molecular-biology reagents that are not an extraction kit and not a PCR master mix: buffers, dyes, ladders' companions, modifying enzymes. Nuclease-free is a claimed property and the reason the bottle costs what it does. A laboratory-grade chemical of the same formula is not a substitute.
Molecular biology here is the handling of DNA and RNA. Extraction kits break the cell and then separate the nucleic acid from protein and from the other nucleic acid. PCR and qPCR reagents copy a chosen sequence so it can be seen. The enzymes and the nucleotides are what the copy depends on. Nuclease contamination destroys the sample before the kit can save it. Sequences are on NCBI Nucleotide. Papers are on PubMed.
Which category should I open next?
