The crimp sealed bottle design helps maintain sterility and ensures consistent results during extended incubation protocols. Each bottle is quality controlled with a 2 week QC hold to confirm performance and reliability, making it suitable for regulated laboratory environments and validated microbiological testing workflows.
Alkali Scientific Phenylethyl Alcohol Agar (PEA) with 5% Sheep Blood, 10/Pk
Phenylethyl Alcohol Agar (PEA Agar) with 5% Sheep Blood is a selective and differential culture medium used for isolating Gram positive organisms, particularly Staphylococcus and Streptococcus species, from mixed clinical or environmental samples. Phenylethyl alcohol inhibits the growth of many Gram negative bacteria by disrupting DNA synthesis and altering membrane permeability, preventing organisms such as Proteus and Pseudomonas from overgrowing cultures. The addition of 5% defibrinated sheep blood supplies essential growth factors and enables observation of hemolytic reactions, allowing differentiation based on hemolysis patterns. Each plate is pre poured with approximately 20mL of sterile agar to provide optimal surface depth for streaking and incubation. These ready to use plates are widely utilized in clinical laboratories, hospitals, diagnostic testing facilities, and microbiology research environments.

Alkali Scientific MacConkey Broth 100mL Bottle, 1/Pk
MacConkey Broth is a selective and differential liquid medium used for the detection and enumeration of coliform bacteria, particularly Escherichia coli, in water, food, dairy, and pharmaceutical samples. Each sterile bottle contains 100 mL of broth typically formulated with bile salts that inhibit Gram positive organisms and support growth of Gram negative enteric bacteria. Lactose is included as the fermentable carbohydrate, while bromocresol purple functions as the pH indicator. When lactose fermenting coliforms grow in the broth they produce acid and often gas. Acid production causes the indicator to shift from purple to yellow, indicating a positive reaction. Absence of color change indicates no lactose fermentation and therefore no detectable coliform activity.
