Description
MN Beads Type B2 are bulk glass beads supplied for sample homogenization and for preparing or refilling bead-based lysis formats. The beads measure 0,3–0,4 mm and are offered as a 750 g pack, described as equivalent to 1000 NucleoSpin Bead Tubes Type B (Mix B1/B2). This bulk presentation suits laboratories that run high sample numbers, prepare custom bead mixes, or prefer to load tubes in-house rather than using only prefilled consumables. Glass beads in the 0,3–0,4 mm range are commonly applied in mechanical disruption workflows for microbial and other biological samples prior to nucleic acid isolation or related analytical steps. MN Beads Type B2 from manufacturer Macherey-Nagel give a defined bead grade for consistent homogenization performance when used with compatible bead mills, tubes, and protocols. The 750 g quantity supports extended method use, kit assembly, and replenishment of bead stocks without frequent reordering of small packs. Integrate the beads into your validated lysis procedures and observe appropriate handling for glass bead media in the laboratory.

Questions about MN Beads Type B2 (Bulk)
What is this article?
MN Beads Type B2 (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 Milieux microbiologiques.
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?
The category is Molecular biology. The sub-category is DNA & RNA extraction kits. The catalogue is Milieux microbiologiques.
Shelves beside this one are Molecular biology reagents (other) and PCR, qPCR & nucleic acid analysis reagents.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
