This kit tests for Wide Range pH using the Octa-Slide 2 Comparator. Range and sensitivity is 5.0, 6.0, 6.5, 7.0, 7.5, 8.0, 9.0, 10.0 pH
This kit tests for QAC using the Direct Reading Titrator method. Range and sensitivity is 0-1,000 ppm/20 ppm, 0-5,000 ppm/100 ppm with dilution.
A masked bromphenol blue indicator is added to the sample and turns green. Sodium tetraphenylboron is added to complex the QAC and the color changes to red. This method is best suited to higher QAC concentrations.
Too Shallow for a Secchi Disk? Turbidity is easily measured by using a standardized turbidity reagent to match the turbidity of a water sample. All the necessary apparatus and reagents needed to test four basic water quality test factors and detailed instructions are housed in a secure foam insert within a rugged field carrying case. Economical reagent refill packages are available for either the entire outfit or individual reagents.
This COD heater block features digital microprocessor control, programmable timer and temperature settings, and a dual LED display to monitor both temperature and timer. Perfect for COD, Total Phosphorus, and Total Nitrogen testing PLUS other tests requiring digestion.
Popular AR-02 outfit provides tests for Hardness, Iron, and pH. Drop count tests for Hardness (10 ppm or 1 gpg/drop). Octa-Slide tests for Iron (0.5-10 ppm) and pH (5.0-10). Includes 100 tests for Iron and 50 tests for each pH and Hardness.
Each kit includes three Octa-Slide 2 color bars with eight translucent color standards in each bar. Two Chlorine color bars and one pH color bar optimize testing.
Hardness and Alkalinity titrations use simple drop count methods and allows either 1 drop equal to 10 ppm or 1 drop equal to 20 ppm. The Acid and Base Demand tests are also drop count procedures.
LaMotte’s Cyanuric Acid tablet dissolves rapidly to provide a cloudy precipitate in the presence of chlorine stabilizer. A calibrated tube is used to measure results by the disappearing dot method.
This kit tests for Calcium Hardness in fresh or salt water. Includes inhibitors to eliminate metal interference’s. All results are as CaCO3. Range/sensitivity is 0-200 ppm/4 ppm CaCO3, 0-2,500 ppm by dilution.
This kit tests for Nitrate-Nitrogen using the LRC Comparator. Range/sensitivity is 0, 0.2, 0.4, 0.6, 0.8, 1.0 ppm NO3-N.
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 can be used for testing pH levels in salt water using the Octa-Slide 2 Comparator. Range and sensitivity is 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4 pH.
