General Life Science Water
Alkali Scientific Peptone Water 0.1% 500mL Bottle, 1/Pk
Peptone Water 0.1% is a sterile, non selective diluent widely used in food safety testing, environmental microbiology, and water quality analysis. This 500 mL bottle format is designed for high volume laboratory workflows where larger quantities of diluent are required for sample preparation. The solution is commonly used for creating primary suspensions of solid food samples prior to microbiological testing, often by adding a measured amount of diluent to homogenized samples in sterile bags. The formulation contains peptone and sodium chloride to maintain osmotic balance and protect microorganisms from stress during handling. By preserving microbial viability without stimulating significant growth, this diluent ensures accurate results in subsequent plating, enumeration, or enrichment procedures.

Alkali Scientific Neutralizing Buffered Peptone Water 400mL Bottle, 1/Pk
Neutralizing Buffered Peptone Water (nBPW) is a pre enrichment medium designed for the recovery of stressed or injured bacteria such as Salmonella and Escherichia coli from food and environmental samples. The 400 mL bottle format is commonly used for whole carcass rinses in poultry testing according to USDA FSIS guidelines. The medium provides a nutrient rich, non selective environment that allows damaged cells to repair and multiply before exposure to selective enrichment media. It also contains buffering and neutralizing components that inactivate residual sanitizers such as chlorine or organic acids that may be present on food surfaces. This step improves detection sensitivity and reduces the likelihood of false negative results in food safety testing.
Alkali Scientific Casein Peptone Lecithin 10% Polysorbate Broth 300mL Bottle, 6/Case
Casein Peptone Lecithin Polysorbate Broth is a specialized neutralizing medium used for microbiological testing of pharmaceutical, cosmetic, and personal care products containing antimicrobial preservatives. Each 300 mL bottle contains a nutrient rich casein peptone base supplemented with lecithin and 10% polysorbate 80. These neutralizing agents inactivate a wide range of disinfectants and preservatives that would otherwise inhibit microbial recovery during sterility or bioburden testing. Polysorbate also acts as an emulsifier, helping disperse oily or viscous samples such as creams, ointments, and lotions within the broth. This formulation ensures accurate detection of microorganisms in products where antimicrobial compounds may be present, making it widely used in pharmaceutical quality control and microbiology laboratories.
