Anionic surfactants are extracted with toluene and break up an ion pair, releasing bromphenol blue into a water layer. Using the drop count method, a standard color reagent is then used to determine the concentration. Range and sensitivity is 1 drop = 1.0 ppm Detergent.
The Insta-Test Ammonia test strips provide a fast and easy method for testing ammonia levels in fresh or salt water. Range/sensitivity is 0, 0.5, 1.0, 3.0, 6.0 (ppm) NH3.
This kit tests for Total Hardness by using the Direct Reading Titrator Method. All results are as CaCO3. Range/sensitivity is 0-200 ppm/4ppm CaCO3.
In 1955, Leavitt et al. discovered that Tryptic Soy Agar facilitated vigorous growth of aerobic and anaerobic microorganisms. This is an enriched media, suitable to support fastidious heterotrophs.
Selective medium for the enumeration of fungi. This formula is prepared with a neutral pH and supplemented with chloramphenicol as the selective agent in fungal medium.
Tryptic Soy Agar is recommended in multiple water & wastewater applications, and numerous standard methods for food testing. TSA is commonly used as a maintenance medium for culture collections and testing bacterial contaminants in cosmetics. Rose Bengal Chloramphenicol Agar is recommended in Standard Methods for the Examination of Water and Wastewater for the enumeration of yeasts and molds from foods and water.

This kit tests for Zinc using the Octa-Slide 2 Comparator. Range and sensitivity is 0, 1, 2, 3, 4, 6, 8, 10 ppm Zn.
These tests strips test for a wide range of pH levels. Range is 0-14/1.0 pH.
This kit tests for Carbon Dioxide where a standard alkali is used to titrate samples to the phenolphthalein endpoint. Range/sensitivity is 0-50 ppm/1.0 ppm CO2.
The Coliform Indicator Test Kit utilizes an easy-to-use, disposable 5-tube method to indicate the presence of Total Coliform Bacteria in a drinking water supply.
Coliform: 5 tubes, each containing a nutrient tablet, are reacted, stored at room temperature for 40-48 hours and examined for color change and gas formation.
Provides equipment to monitor nine parameters most critical for the salt water aquaculturist. Reagents, labware, and accessories are mounted in ethafoam for convenient test selection and portability. Short form lid label instructions are always available for quick reference, and a long form booklet provides detailed instructions with kit diagram. Unit is supplied complete with labware, accessories, sampling bottles, and reagents for 50 tests of each factor.
