Pickering Laboratories Inc Artificial Perspiration, ISO 11641, Stabilized, each (200 mL/bottle)

Perspiration is on everything we touch with our fingers or that comes into contact with our bodies. Sweat can react with materials and trigger allergies, or it can shorten product service life via corrosion or discoloration. Natural human perspiration has a complex composition that depends on the type of sweat gland, the person’s metabolism and hydration level. This formulation, per ISO 11641, determines colorfastness to perspiration of leather at all stages of processing, particularly to gloving, clothing and lining leathers, and uppers of unlined shoes. This alkaline perspiration has a greater effect on the color of leather and is used to simulate the most demanding conditions.

Santa Cruz Biotechnology Hydrogen Peroxide,7722-84-1,500mL

Molecular Formula H2O2, Molecular Weight 34.01, Synonyms oxydol; perhydrol, Hydrogen peroxide (H2O2) is an incredibly ubiquitous oxidant used as a reagent, disinfectant, antiseptic, and propellant. In synthetic chemistry, H2O2 is used for epoxidation and hydroxylation transformations, and is used as the raw oxidant source for generating more complicated and specific organic/inorganic peroxides. H2O2 in aqueous solution is used as a laboratory disinfectant and as a topical antiseptic. The disinfectant, bleaching, and non-toxic properties of H2O2 provide a wide scope of industrial and commercial applications.

AdipoGen Gram’s Safranin Solution (250 ml)

Gram’s Safranin Solution (250 ml), Adipogen Life Sciences. Chemical. CAS: 477-73-6. Formula: C20H19ClN4. MW: 350.84. Synthetic. Gram Safranin Solution is a reagent recommended for use in qualitative procedures to differentiate gram-negative from gram-positive organisms. The Gram staining allows a fast differentiation of bacteria in Gram-positive and Gram-negative. The mureine structure of the bacteria walls is the basis of the color affinity. Bacteria will be stained with Gram's crystal violet solution - an aniline dye - in the first step. After the treatment with iod solution, a dye-iod complex will form. During the decolorizing step, this complex stays in the multilayer mureine structures of the Gram-positive bacteria and they will appear blue. Gram-negative bacteria have a monolayer mureine structure only, the dye-iod complex does not stay bound to the cellwall, they will be decolorized. Gram-negative bacteria will be counterstained by safranin solution and appear orange.
