Factory QA benches checking incoming ingredients and finished product: moisture, pH, water activity, and microbial counts. Most orders here repeat against a fixed test method rather than changing month to month. Lab reagents, culture media and everyday consumables: Merck and RCI-Labscan solvents and analytical-grade chemicals, Merck and Difco media, pH buffers and conductivity standards, chlorine and hardness test kits, pipette tips, microtubes, Petri dishes and Whatman filter paper. Send the list with grade and pack size, and we will quote it free on the same quotation as your instruments and glassware.
For measuring pH in various industries including food, beverage, textile and cosmetics, and for checking the acidity and alkalinity of raw water sources and wastewater treatment ponds.
The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference…

The HI83742-25 is a high quality reagent that is pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. This reagent allow for a direct reading of the sample.
The HI83740-20 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow a method in which the reaction between copper and reagents causes a purple tint in the sample.

The HI83741-20 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow a method in which the reaction between iron and reagents causes a purple tint in the sample.
Lauryl sulfate broth (LSB) is widely used to detect coliform bacteria in wastewater, dairy products, other food products and clinical samples. It is a cream-yellow, homogeneous, free-flowing powder that dissolves readily in water at 25 °C, pH 6.8 ± 2.
Pack size 500 g. Bacto™ Tryptone is used in preparing microbiological culture media. Ingredients, where noted, meet United States Pharmacopeia (USP) performance specifications.
HI84102-60 is a pH 7.00 calibration buffer produced in accordance with ISO 3696/BS3978 standards using high purity salts, deionized water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers.
HI84102-61U is a pH 8.20 calibration buffer produced in accordance with ISO 3696/BS3978 standards using high purity salts, deionized water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers.
Plate count agar (PCA) culture medium is used for total microbial count testing of samples such as food, drinking water and other sample types. This medium complies with EN ISO 4833, ISO 17410, FDA-BAM and APHA.
Pack size 500 g. Plate Count Agar and Standard Methods Agar (Plate Count Agar; Tryptone Glucose Yeast Agar) are used for obtaining microbial plate counts from milk and dairy products, foods, water and other materials of sanitary importance.
Potato Dextrose Agar (PDA) culture medium is used to test for moulds and yeasts found in food, drinking water and other types of sample. This medium complies with the American Public Health Association for food (1992) and the United States Pharmacopeia.
Pack size 500 g. Potato Dextrose Agar is used for the cultivation and enumeration of yeasts and molds. Potato Dextrose Agar meets United States Pharmacopeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP) performance specifications, where applicable.
