SHORT DESCRIPTION

Dextrose Monohydrate Glucose Extra Pure is a laboratory-grade form of glucose with one molecule of water per glucose unit, offering high purity and excellent solubility in water. It serves as a vital energy source in microbiological culture media, fermentation experiments, and biochemical assays. Its predictable behavior and minimal impurities make it suitable for preparing reagents, buffers, and standard solutions in analytical and biological research. This compound is especially useful in cell culture work and metabolic studies where glucose is a key variable. Store in an airtight container away from moisture and direct sunlight to maintain its crystalline integrity.
