Alkali Scientific Gelatin Phosphate Buffer 0.2% 250mL Bottle, 1/Pk

Supplier:  Alkali Scientific GPGB00

Gelatin Phosphate Buffer (0.2%) is a sterile diluent and suspending medium designed to maintain the viability and stability of microorganisms during sample preparation and dilution procedures. Each bottle contains 250mL of phosphate buffered solution supplemented with 0.2% gelatin. Unlike simple saline or phosphate buffered solutions, the gelatin component acts as a protective stabilizer that coats microbial cells and helps prevent damage caused by osmotic stress or physical agitation during processing. This protection is particularly important when handling fragile or low concentration microbial samples. The buffer maintains a stable, near neutral pH environment that preserves cellular integrity throughout testing. It is commonly used in food microbiology, water quality analysis, and environmental monitoring protocols for sample dilution, microbial recovery, and membrane filtration procedures.
