"Spectrophotometer"

Supplier: CHEMetrics

CHEMetrics test kits measure total acid soluble sulfides and employ the methylene blue methodology. Sulfides react with dimethyl-p-phenylenediamine in the presence of ferric chloride to produce methylene blue.

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.

The Pierce™ Coomassie Plus™ Protein Assay is a quick and ready-to-use, reducing agent-compatible, improved Bradford assay to quickly measure (A595 nm) total protein concentration compared to a protein standard.

Supplier: G-Biosciences

G-Biosciences' NUCLEIC dotMETRIC™ kit provides a quick and accurate method for detecting and measuring nucleic acid concentration, including DNA, RNA and oligonucleotides

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.
