Description
Screw-on lids with silicone sealing are polypropylene closures intended for laboratory screw-in vessels and cryogenic tubes used in molecular biology, microbiology and cell-culture work. Each lid is moulded from PP and fitted with a silicone sealing element to support a secure fit on compatible tubes during routine handling and storage. The red colour provides clear visual coding on the bench, helping operators distinguish samples, process steps or vessel types at a glance. Supplied loose as a pack of 1000 pieces, the format suits high-throughput laboratories that need a ready stock of matching lids. The pack weighs 0,375 kg and is practical for everyday replenishment of tube and screw-cap systems. These lids from manufacturer ROTH SELECTION align with standard labware assortments for cryogenic tubes and screw-in vessels. They are suited to general laboratory use where reliable PP closures with silicone sealing are required. Colour-coded red lids integrate easily into organised workflows without adding complexity to sample handling. Select this bulk pack when consistent screw-on lids are needed for molecular biology and related tube applications.

Questions about Screw-on lids, PP, with silicone sealing, red, loose, 1000 unit(s)
What is this article?
Screw-on lids, PP, with silicone sealing, red, 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.
