Alkali Scientific Fluid A 100mL Bottle, 1/Pk
Supplier: Alkali Scientific FAMB00
Fluid A is a sterile rinsing and diluting fluid formulated according to United States Pharmacopeia (USP) specifications for sterility testing. Each bottle contains 100mL of a clear solution composed of 0.1% peptic digest of animal tissue (peptone) in purified water. The formulation contains no antimicrobial preservatives or selective agents, ensuring compatibility with sensitive microbiological assays. Fluid A is commonly used in pharmaceutical and medical device sterility testing as a membrane filtration rinse. After a sample passes through the membrane filter, this fluid washes away bacteriostatic or fungistatic residues that could inhibit microbial growth in subsequent culture media. By removing these inhibitory substances, the fluid helps prevent false negative results. It also functions as a general microbial diluent for preparing suspensions of non fastidious organisms.
