The simple, efficient, and reliable way to stay connected to your critical environments, wherever you go.

Use the CRISPR/Cas9 system in vitro to cut DNA in a tube and analyze the results with gel electrophoresis.

High/Low Alarm with Time/Date Stamp is an alarm tracking feature which stores in memory each alarm event, detailing when the alarm state occurred, as well as when the unit returned back to within range.

The NED method is widely used in the quantitative analysis of nitrite and nitrate in water samples. NED readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored pink azo compound. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Due to the significant intensity of the developed color even at very low nitrite/nitrate concentrations, lower detection limits and measurement ranges are possible vs. chromotropic acid kits. In addition, the nitrate measurement uses only zinc which is less toxic than cadmium, making handling and disposal safer.

This pH tester is sleek tester is accurate to 0.1 pH with a built-in thermometer to automatically adjust the pH reading for temperature. The waterproof design (it floats), simple operation, and replaceable electrode mean that you can rely on this meter for years. The large LCD display shows both pH and temperature readings simultaneously, while a stability indicator is displayed to alert you when a stable reading has been obtained.

When general laboratory grade water (Type III) is all you need, then PURELAB Chorus 3 is the reliable solution with the flexibility to suit your requirements.

When Type II water is all you need, then PURELAB Chorus 2 (RO/DI) is the reliable solution with the flexibility to suit your requirements.

This multiparametrer tester is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off.
