Description
MN Beads Type D (Bulk) are Type D steel beads offered as a 500 g bulk pack for laboratory homogenization and sample disruption. The beads have a diameter of 3 mm and are intended for bead-beating applications that demand dense metallic media to break down resistant sample types. This bulk quantity corresponds to the bead content of 1000 NucleoSpin Bead Tubes Type D, enabling economical refilling of compatible tubes and flexible preparation of custom lysis setups. Steel Type D beads are commonly used when high mechanical energy is required for hard tissues, seeds, or other challenging matrices ahead of nucleic acid isolation or analytical workup. Available from manufacturer Macherey-Nagel, the bulk format suits core facilities and high-throughput laboratories that prefer to stock grinding media separately from consumable tubes. Consistent 3 mm steel bead geometry supports reproducible homogenization performance across large numbers of preparations while simplifying inventory for Type D workflows.
This article is part of DNA & RNA extraction kits, in Molecular biology.

Questions about MN Beads Type D (Bulk)
What is this article?
MN Beads Type D (Bulk) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in DNA & RNA extraction kits, inside Molecular biology, in Microbiology lab supplies.
An extraction kit lyses the sample and then binds the nucleic acid, usually on a column or on a bead, and washes the rest away. Kits for blood, tissue, soil or a PCR cleanup are different chemistries. Yield and the size of fragments they keep are in the protocol. An RNA kit has to protect against RNase.
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?
