Alkali Scientific ChromX™ Orientation Chromogenic Agar, 20 mL, 10/Pk
ChromX™ Chromogenic Culture Media are specialized selective and differential agar formulations designed for rapid isolation and presumptive identification of clinically relevant microorganisms. The chromogenic substrates incorporated into the medium produce distinct colony colors when metabolized by target organisms, allowing laboratories to visually differentiate species directly on the plate. This capability reduces additional confirmation testing and improves diagnostic efficiency in routine microbiology workflows. Each plate is supplied ready to use with approximately 20 mL of prepared medium, supporting consistent growth conditions and reliable performance. Packaged in convenient multi plate formats, ChromX™ media are ideal for clinical laboratories, food safety testing, environmental monitoring, and research facilities requiring accurate microbial detection and streamlined laboratory processing.
Alkali Scientific Todd Hewitt Broth with CAN 3mL 13x100, 10/Pk
Todd Hewitt Broth with CAN, 3mL, 13x100mm Tube, 10/Pk is a selective enrichment medium formulated for the isolation and cultivation of Group B Streptococcus (GBS) from clinical specimens, particularly in prenatal screening procedures. The broth is supplemented with the antibiotics colistin and nalidixic acid (CAN), which suppress many Gram negative bacteria and background flora while allowing selective growth of GBS organisms. Each tube contains 3mL of sterile medium in a 13x100mm screw cap tube designed for convenient inoculation and incubation in microbiology laboratories. The ready to use format supports standardized diagnostic workflows and reliable enrichment performance. This medium is commonly used in clinical diagnostics, hospital laboratories, and microbiology testing programs focused on detecting Group B Streptococcus.
Alkali Scientific Schaedler Agar 500mL Bottle, 1/Pk
Schaedler Agar is a nutrient rich culture medium designed for the recovery and cultivation of anaerobic bacteria. These organisms cannot tolerate oxygen and often require specialized nutrients for successful growth. The formulation includes peptones, yeast extract, and dextrose to provide abundant energy sources that support bacterial metabolism. It is also enriched with hemin, an essential growth factor required by many anaerobic species for cellular respiration processes. Reducing agents within the medium help maintain a low oxidation reduction potential, creating conditions suitable for oxygen sensitive microorganisms. Schaedler Agar is widely used in clinical and research laboratories to isolate anaerobic pathogens from wound infections, blood cultures, and deep tissue samples.

Alkali Scientific LB Agar (Lennox) w/4% Glycerol 20mL Plate, 10/Pk
LB Agar (Lennox) with Ampicillin is a convenient pre mixed selective medium widely used in molecular biology for isolating plasmid transformed Escherichia coli. Each plate contains 20 mL of Lennox formulation Lysogeny Broth agar (5 g/L NaCl) supplemented with 100 µg/mL Ampicillin. This ready to use format eliminates the time consuming and temperature sensitive process of adding antibiotics to molten agar. The 100 µg/mL concentration is the standard for maintaining high copy number plasmids carrying the bla gene (beta lactamase). Ampicillin inhibits cell wall synthesis, preventing the growth of non resistant cells, while transformed bacteria degrade the antibiotic and form colonies. The Lennox low salt formulation is beneficial for salt sensitive downstream applications and routine cloning workflows.
Alkali Scientific Agar, Granulated, High Gel Strength, 1 Kg
Agar, Granulated, High Gel Strength, 1 Kg, is a high-quality agar product used to prepare solid culture media for microbiological and biotechnological research. The high gel strength ensures that the agar remains firm during incubation, providing a stable surface for microbial growth. This product is commonly used to prepare nutrient agar, Sabouraud Dextrose Agar (SDA), and other specialized media for the isolation and cultivation of bacteria, fungi, and yeasts. The granulated form is easy to use and provides precise control over agar concentration, making it ideal for routine microbiological testing, research, and diagnostic applications in clinical and industrial laboratories.
Alkali Scientific Orange Serum Agar10mL 60 x 15 mm Filter plate, 10/Pk
Orange Serum Agar (OSA) is a specialized culture medium developed primarily for the detection and enumeration of aciduric spoilage microorganisms in citrus and fruit juice products. The formulation contains nutrients derived from orange serum along with additional growth factors that replicate the natural environment of fruit beverages. The medium is adjusted to an acidic pH that suppresses many neutral pH bacteria while supporting organisms capable of growing under acidic conditions. These include acid tolerant bacteria, yeasts, and molds that can cause spoilage in processed juices and beverage products. This format is prepared in a 10 mL filter plate configuration suitable for microbiological quality control testing in beverage production laboratories and research settings.
Alkali Scientific LB Agar (Lennox) 20mL Plate, 10/Pk
LB Agar (Lennox formulation) is a widely used general purpose microbiological medium designed for the cultivation and maintenance of Escherichia coli and other laboratory bacterial strains. Each plate contains approximately 20mL of agar prepared from tryptone, yeast extract, and sodium chloride, providing a rich nutrient environment that supports rapid bacterial growth. The Lennox formulation differs from the Miller formulation by containing a reduced sodium chloride concentration of 5 g/L, making it suitable for applications where lower ionic strength is preferred. This medium is commonly used in molecular biology workflows such as cloning, plasmid maintenance, transformation experiments, and bacteriophage propagation. The nutrient rich composition provides essential amino acids, vitamins, and peptides that support robust colony development on solid culture surfaces.

Alkali Scientific Fluid Thioglycollate Medium (FTM) 1000mL Bottle, 1/Pk
Fluid Thioglycollate Medium (FTM) is a standard liquid enrichment medium used for sterility testing of pharmaceutical products and biological materials in accordance with United States Pharmacopeia (USP <71>) guidelines. Each bottle contains 1000mL (1 liter) of nutrient rich broth designed to support the growth of aerobic, anaerobic, and microaerophilic microorganisms. The formulation includes sodium thioglycollate and L cystine which act as reducing agents to create anaerobic conditions deeper in the medium while the surface layer remains oxygenated. A small amount of agar stabilizes the oxygen gradient by preventing convection currents. Resazurin serves as an oxidation indicator, turning pink in oxygen rich areas while the deeper anaerobic zones remain clear. This large volume format is ideal for high throughput sterility testing and routine microbiological quality control.
