Dehydrated Microbiology Media
Alkali Scientific Tryptic Soy Broth (TSB), 1 mL, 13 × 100 mm Polycarbonate Tube, Screw Cap, 10/Pk
Tryptic Soy Broth (TSB), 1 mL, 13 × 100 mm Polycarbonate Tube, Screw Cap, 10/Pk. Perfect for microbial culture use, these polycarbonate tubes are screw-capped to ensure a secure seal, ideal for laboratory environments requiring precision in microbial culture growth in a variety of conditions.
Alkali Scientific Modified Edwards w/Bovine Plasma Plate, 10/Pk
Modified Edwards Agar with Bovine Plasma is a selective and differential medium designed for the isolation and identification of Streptococcus species associated with bovine mastitis, particularly Streptococcus agalactiae. The formulation contains selective agents such as crystal violet and thallium sulfate that suppress contaminating organisms commonly present in raw milk, allowing streptococci to grow more clearly. Differentiation is primarily based on esculin hydrolysis. Organisms capable of hydrolyzing esculin react with ferric ions in the medium to form dark brown or black colonies, while Streptococcus agalactiae typically remains blue or colorless. The addition of bovine plasma enriches the medium and enhances characteristic colony appearance, supporting reliable screening of dairy samples in veterinary and food microbiology laboratories.
Alkali Scientific R2A Agar, 20 mL, 100 × 15 mm Plate, Oxoid Formulation, 5 Day QC, 10/Pk
R2A Agar, 20 mL, 100 × 15 mm Plate, Oxoid Formulation, 5 Day QC, 10/Pk. This agar is designed for cultivating bacteria in laboratory environments, providing clear, consistent growth. The Oxoid formulation ensures reliable results in microbial testing, and the 5-day QC ensures the highest quality. This product is ideal for research and industrial applications.
Alkali Scientific Phenol Red Broth w/Maltose and Durham Tube 8mL, 10/Pk
Phenol Red Broth with Maltose and Durham Tube is a differential test medium used to determine whether microorganisms can ferment the carbohydrate maltose. The broth contains maltose as the sole fermentable sugar and phenol red as the pH indicator. When an organism ferments maltose, acid is produced and the medium changes color from red to yellow. If fermentation also produces gas, the gas collects in the inverted Durham tube placed inside the broth. Lack of fermentation leaves the broth red, while alkaline reactions may produce a pink coloration. This test is widely used in microbiology laboratories for the identification and differentiation of Gram negative enteric bacteria and other microorganisms based on their carbohydrate fermentation patterns.
S2 Media 100mL Tryptic Soy Broth with Lecithin and Tween 20 (TSA w/LT20), 180mL Wide Mouth PC Jar, 1/each
Tryptic Soy Broth with Lecithin and Tween 20(TSB w/LT20) is a general-purpose, enriched medium recommended for the detection and recovery of microorganisms in environmental monitoring where disinfectant residues may be present. It is also recommended for sterility testing products. The addition of lecithin and Tween 20 serve as neutralizers for quaternary ammonium compounds and phenolic disinfectants, respectively, enhancing the recovery of organisms that may be stressed or injured by cleaning agents. This medium was developed between the 1970's and 1980's to address an increasing demand for reliable microbial recovery in pharmaceutical settings and cleanroom environments.• Product meets APHA, CLSI, USP-NF and SMWW reference methods and performance criteria.• TSB w/LT20 should be used by trained professionals within a laboratory setting. • Product is not intended for use in the diagnosis or treatment of disease or other human conditions.
HIMEDIA T.A.T. Broth Base, M562, Microbiology Culture Media, Dehydrated Culture Media, Broth Base, Sterility Testing, Viscous and Cosmetic Products, Powder, 5 kg
T.A.T. Broth Base, prepared with added polysorbate 20, is designed for the sterility testing of highly viscous or gelatinous products such as salves, ointments and other cosmetics. Casein enzymic hydrolysate provides rich nutrition while azolectin and polysorbate 20 neutralize preservatives and antimicrobial residues that would otherwise mask contamination, final pH 7.2. The result is sensitive recovery of any surviving organisms from challenging sample matrices. Dehydrated powder, store in a cool dry place. Packaged as 5 kg.
S2 Media 1L D/E (Dey-Engley) Neutralizing Broth without Tween in 1L Media Bottle, 1ea
D/E (Dey-Engley) Neutralizing Broth without Tween 80 is utilized for the neutralization and testing of antiseptics and disinfectants according to the procedures of Engley and Dey. The broth contains a high concentration of lecithin (7.0g/L) and is opaque in appearance. Therefore, turbidity alone cannot be used as a visual indication of growth and subculture onto a suitable solid media is recommended. Organisms that ferment dextrose will cause a color shift from purple to yellow. Species that do not ferment dextrose can form pellicles on the surface of the medium. • Product meets AAMI, APHA, ISO, SM-Dairy, and USP-NF reference methods and performance criteria.• D/E Neutralizing Broth should be used by trained professionals within a laboratory setting. • Product is not intended for use in the diagnosis or treatment of disease or other human conditions.• Product does not contain polysorbate 80.
