Dehydrated Microbiology Media
Alkali Scientific Sabouraud Dextrose Agar (SDA) w/ 5% Soy Lecithin & 4% Tween 20 100mL Bottle, 12/CS
Sabouraud Dextrose Agar with Soy Lecithin and Tween 20 is a specialized neutralizing medium designed for environmental monitoring in pharmaceutical and industrial facilities. The formulation contains powerful neutralizers that deactivate residues from disinfectants and cleaning chemicals commonly used on laboratory and manufacturing surfaces. Soy lecithin helps neutralize quaternary ammonium compounds, while Tween 20 neutralizes phenolic disinfectants and related chemicals. These additives prevent residual disinfectants from killing microorganisms during testing, ensuring accurate recovery of fungi from sampled surfaces. The medium is widely used in environmental monitoring programs where reliable detection of microbial contamination is essential.

MOLTOX Molecular Toxicology Inc Fluid A w/ 2% Tween 80 & 0.3 % Lecithin, 90 mL/bottle, Store in Refrigerator
This item has a minimum order quantity of 96 per supplier requirements. Fluid D is peptone water (Fluid A) with the addition of Polysorbate (Tween) 80. It is used for diluting or rinsing when performing sterility testing. Tween 80 acts as a surfactant which will break down any residue present. Each lot of media from MOLTOX is tested for sterility, where applicable, and its ability to support the growth of the appropriate microorganism. All media are accompanied by GLP-compliant formulation and Quality Control certificate.
Alkali Scientific Tryptic Soy Broth (TSB) w/Lecithin & Tween 80 500mL Bottle, 1/Pk
Tryptic Soy Broth (TSB) with Lecithin & Tween 80 500mL Bottle, 1/Pk. Perfect for microbial growth and neutralizing agents in laboratory environments. This 500mL bottle provides an ideal quantity for smaller tests and experiments. Lecithin and tween 80 included to enhance neutralization and microbial growth support. This product is highly effective in studies and procedures that require optimal neutralization and microbial differentiation.
Alkali Scientific Phenylehanol Agar (PEA), 15x100mm, 10/pk
Phenylethyl Alcohol (PEA) Agar, 15×100mm plates supplied in packs of 10, is a selective culture medium formulated for the isolation of Gram positive bacteria from mixed clinical or environmental specimens. The presence of phenylethyl alcohol inhibits the growth of Gram negative organisms by interfering with DNA synthesis, allowing clearer recovery of Gram positive cocci such as Staphylococcus and Streptococcus species. This selective property makes PEA agar particularly useful when samples contain mixed microbial populations where Gram negative bacteria might otherwise overgrow the culture. The medium is commonly used in clinical microbiology, research laboratories, and quality control environments. Each plate is pre poured with sterile agar to a consistent depth to ensure reliable growth conditions and reproducible laboratory results.
Alkali Scientific Indole Broth 4mL Tube, 10/Pk
Indole Broth, commonly referred to as Tryptone Water, is a biochemical test medium used to determine the ability of microorganisms to produce indole from the amino acid tryptophan. Each tube contains 4mL of nutrient broth rich in tryptophan containing peptones that serve as substrates for bacterial metabolism. Organisms possessing the enzyme tryptophanase break down tryptophan to produce indole, pyruvic acid, and ammonia during incubation. After incubation, the presence of indole is detected by adding Kovac’s or Ehrlich’s reagent, which reacts with indole to produce a characteristic red layer at the liquid surface. A positive reaction indicates organisms such as Escherichia coli or Proteus vulgaris, while negative reactions remain yellow or unchanged. This test is an essential component of the IMViC series used to differentiate Enterobacteriaceae.
Alkali Scientific Todd Hewitt Broth 100mL, 125mL Bottle, 1/Pk
Todd Hewitt Broth is a nutrient rich culture medium used for cultivating Streptococcus species and other fastidious bacteria. The formulation includes buffering components that prevent excessive acid buildup during bacterial growth. Streptococci produce acid as they metabolize nutrients, which can inhibit their own growth in standard media. The buffering system maintains a stable pH environment, allowing sustained growth and higher bacterial yields. This makes the medium particularly useful for clinical diagnostics, serological testing, and research applications. The 100mL bottle format provides sufficient volume for routine laboratory use and bacterial culture preparation.
ATHENA ES LB (Lennox)
Athena offers three variations of the basic nutrient-rich LB Broth media (Miller, Lennox, and Luria) as well as their APF Certified™ equivalents made using Athena’s proprietary blended plant protein hydrolysate: Atholate™. The formulations each provide an abundance of peptides and peptones, vitamins and trace elements, and differ only in sodium chloride content and whether they were made with casein hydrolysate or Atholate™. The differences allow the researcher to select which formula will provide the ideal osmotic conditions for their particular bacterial strain and desired culture conditions. Each LB Broth and APF LB Broth can be custom ordered in bulk.
