When precise temperature measurements are required, WPI can provide you with a very accurate monitor and thermocouple microprobes. WPI monitors have both resolution and accuracy of 0.1 °C in the 0 to 50 °C range and are traceable to NIST standards, whereas other competitive electronic thermometers have an accuracy that is usually to 0.5 °C or worse. Furthermore, all our type T clinical probes are guaranteed accurate to 0.1 °C, due to our stringent wire standards. These are five times more accurate than competitive probes made with regular 'Special Limits' wire.

Supplier: CHEMetrics

Dissolved Oxygen in water test kits for environmental and drinking water applications (ppm range) employ the indigo carmine method. The reduced form of indigo carmine reacts with D.O. to form a blue product. The indigo carmine methodology is not subject to interferences from temperature, salinity, or dissolved gases such as sulfide, which plague users of D.O. meters.

Pierce BCA™ (bicinchoninic acid) reagents provide accurate determination of protein concentration with most sample types encountered in protein research. The Pierce BCA™ Protein Assay can be used to assess yields in whole cell lysates and affinity-column fractions, as well as to monitor protein contamination in industrial applications. Compared to most dye-binding methods, the BCA™ Assay is affected much less by protein compositional differences, providing greater protein-to-protein uniformity.
