HPTLC plates, silica gel 60, unmodified layers, Nano-ADAMANT

Supplier: MACHEREY-NAGEL
Description: Unmodified HPTLC silica layers available as glass plates with or without fluorescent indicator. The narrow fractionation of the silica particles features theoretical plate heights, which are one order of magnitude smaller than on standard silica layers. Thus, Nano-ADAMANT has the advantage of sharper separations, shorter developing times, and increased detection sensitivity with equal selectivity.

Silicon dioxide 200-500 µm

Catalog Number: (ICNA0202809)
Supplier: MP Biomedicals
Description: MP EcoChrom™ SILICA is used as a suspending and thickening agent in pharmaceutical.A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. In the majority of silicates, the Si atom shows tetrahedral coordination, with 4 oxygen atoms surrounding a central Si atom.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 200-500μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

Latex toxin detection kits, RPLA

Supplier: THERMO FISHER DIAGNOSTICS
Description: The technique of reversed passive latex agglutination (RPLA) enables soluble antigen such as bacterial toxins to be detected in an agglutination assay. In a standard agglutination assay, soluble antibody reacts with particulate antigen such as bacterial cells. However, in a reversed agglutination assay the antibody, which is attached to particles, reacts with the soluble antigen. The particles (in this case, latex) do not themselves play a part in the reaction and they are therefore passive.
