Alkali Scientific Fluid A 500mL Bottle, 1/Pk
Fluid A is a sterile rinsing and diluting fluid prepared according to United States Pharmacopeia (USP) specifications for sterility testing. Each bottle contains 500mL of a clear solution consisting of 0.1% peptic digest of animal tissue (peptone) dissolved in purified water. The formulation contains no antimicrobial preservatives or selective additives, ensuring compatibility with microbial recovery procedures. In pharmaceutical and medical device sterility testing, Fluid A is widely used as a membrane filtration rinse to remove bacteriostatic or fungistatic residues remaining on the filter after sample processing. Eliminating these inhibitory compounds prevents suppression of microbial growth during incubation and reduces the risk of false negative results. The fluid also serves as a general purpose diluent for preparing microbial suspensions and routine microbiological testing workflows.
Alkali Scientific Selenite Cystine Broth 10mL 16x125mm Glass, 10/Pk
Selenite Cystine Broth, 10mL, 16x125mm Glass Tube, 10/Pk is a selective enrichment medium formulated for the isolation of Salmonella species from clinical, food, and environmental samples. The presence of selenite inhibits many competing Gram positive and enteric organisms, while cystine enhances recovery and growth of Salmonella cells in mixed microbial populations. Each tube contains 10mL of broth in a 16x125mm screw cap glass tube designed for convenient incubation and standardized laboratory workflows. The ready to use format reduces preparation time and ensures consistent medium performance. Commonly used in food safety testing, clinical microbiology, and environmental monitoring laboratories, this enrichment medium supports accurate detection of Salmonella in regulated microbial quality control applications.
