Coliform Media
Alkali Scientific Lauryl Tryptose Broth (LTB) 2X w/Tube 100mL Bottle, 1/Pk
Lauryl Tryptose Broth (LTB) 2X is a double strength selective liquid medium formulated for the detection and enumeration of coliform bacteria in water, wastewater, and food samples. Each container is filled with 100mL of nutrient rich broth containing tryptose, lactose, and sodium lauryl sulfate. The double strength formulation allows laboratories to add an equal volume of aqueous sample without diluting the medium below effective working concentrations. Sodium lauryl sulfate suppresses the growth of non coliform organisms while lactose acts as the fermentable carbohydrate source. A positive presumptive result is indicated by turbidity and gas production during incubation. This medium is widely used as the first stage of the Most Probable Number (MPN) method for routine water quality monitoring, environmental testing, and food safety analysis.
Alkali Scientific Lauryl Sulfate Tryptose Broth 10mL, 10/Pk
Lauryl Sulfate Tryptose (LST) Broth, 10mL Tubes, 10/Pk is a selective enrichment medium designed for the detection of coliform bacteria in water, food, and environmental samples. The formulation includes sodium lauryl sulfate, which inhibits the growth of non coliform organisms, while tryptose provides a nutrient rich base that supports the growth of Escherichia coli and related coliform species. Supplied in sterile 10mL tubes, the medium is suitable for Most Probable Number (MPN) testing and microbial limit analysis in quality control laboratories. The ready to use format simplifies preparation and maintains consistent testing conditions. LST broth is widely used in environmental monitoring, food safety testing, and microbiology laboratories for reliable detection and enumeration of coliform organisms.

S2 Media 10mL EC Medium with MUG, 12mL Polypropylene Conical Tube with Inverted Durham Tube, 50/box
EC (Escherichia coli) Medium with MUG is a selective and differential broth utilized for the fluorogenic detection of Escherichia coli. Feng and Hartman developed a rapid assay for E. coli by incorporating 4-methylumbelliferyl-β-D-glucuronide (MUG) into Lauryl Tryptose Broth at a final concentration of 100µg/mL. Moburg determined the amount of MUG could be reduced to a final concentration of 50µg/mL without adversely affecting results. • Product meets APHA, BAM, EPA, ISO, and SMWW reference methods and performance criteria.• EC MUG 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.
Hach Company Presence/Absence Broth with MUG, Ampules, pk/25
Presence/Absence Broth with MUG ampules provide an easy-to-use test, ideal for screening drinking water samples for the presence of Total Coliforms and E. coli bacteria. Simply combine the P/A broth with your 100mL sample and incubate for 24 to 48 hours at 35 degrees Celcius. A color change to yellow or yellow brown indicates presence of coliform bacteria.
