Gallium Selenide Industrial Grade 99.99%

Gallium selenide includes gallium(III) selenide and gallium(II) selenide, which are minor metalselenides. Ga2Se3 is reddish black brittle hard lumps, ingot piece or powder, however GaSe is dark brown crystal, which are both photoelectric material. GaSe is layer structure semiconductor as GaS. With temperature decrease, Max value of its photoelectric effect move to shortwave end. Selenium metal and gallium metal are raw material for both Ga2Se3 and GaSe.

Gentisic Acid

Gentisic acid is a dihydroxybenzoic acid. It is a derivative of benzoic acid and a minor product of the metabolic break down of aspirin, excreted by the kidneys. As a hydroquinone, gentisic acid is readily oxidised and is used as an antioxidant excipient in some pharmaceutical preparations. In the laboratory, it is used as a sample matrix in matrix-assisted laser desorption/ionization mass spectrometry.

Germanium Metal Industrial Grade 99.999%

Germanium wafer is customs against the requirements. Its sources can be monocrystal germanium and polycrystal, which are all optical crystals. Optical germanium crystal own great permeation performance at wave length between 2-14μm. They have good chemical stability, corrosion resistance and machinability, which get wide applications in windows and lens of thermal imagery system.

Germanium Wafer

It can process into disk, rectangular piece, window, lens, prism and other special shapes.

Diameter of monocrystal germanium wafer can reach 300mm

Diameter of polycrystal germanium wafer can reach 380mm

Gibberellic Acid

Gibberellic acid is a hormone found in plants. It is a simple gibberellin, promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants develop tolerance for it. Gibberellic acid is sometimes used in laboratory and greenhouse settings to trigger germination in seeds that would otherwise remain dormant. It is also widely used in the grape-growing industry as a hormone to induce the production of larger bundles and bigger grapes, especially Thompson seedless grapes, and in the Okanagan and Creston Valley it is used in the cherry industry as a growth regulator.

Glutaraldehyde

Glutaraldehyde is an organic compound. It is used to disinfect medical and dental equipment. It is also used for industrial water treatment and as a chemical preservative. It is sometimes employed in the tanning of leather. Glutaraldehyde is frequently used in biochemistry applications as an amine-reactive homobifunctional crosslinker. Glutaraldehyde is probably the most commonly used EM fixative and is normally supplied at concentrations of 25 or 50% and used at concentrations of 0.5-2%.

Glycidyl Methyl Ether

Glycidyl Methyl Ether is a clear colourless liquid used as a general purpose diluent to reduce viscosity of epoxy resins,favoring improved filler loading and substrate wetting and resulting in faster curing time. It is also used as a stabilizer for chlorinated vinyl resins and rubber. It is used as a chemical intermediate to make other compounds.

Glycine

Glycine is an organic compound. With only two hydrogen atoms as its 'side chain', glycine is the smallest of the 20 amino acids commonly found in proteins. It is unique among the proteinogenic amino acids in that it is not chiral. It can fit into hydrophilic or hydrophobic environments, due to its two hydrogen atom side chain. Glycine is an intermediate in the synthesis of a variety of chemical products. It is used in the manufacture of the herbicide glyphosate. It serves as a buffering agent in antacids, analgesics, antiperspirants, cosmetics, and toiletries. It is also used as an additive in pet food and animal feed. Pharmaceutical grade glycine is produced for some pharmaceutical applications, such as intravenous injections.

Glycogen

Glycogen is a molecule that functions as the secondary long-term energy storage in animal and fungal cells. It is made primarily by the liver and the muscles, but can also be made by glycogenesis within the brain and stomach. It is the analogue of starch, a less branched glucose polymer in plants, and is commonly referred to as animal starch, having a similar structure to amylopectin. It is found in the form of granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle. It forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact than the energy reserves of triglycerides.
