Flexible Teflon microprobes are used for implantation in tissue, in spectrophotometer cuvettes, rectally in neonatal mice, in water baths, PCR thermal cyclers, etc. Also, measure animal rectal temperatures during surgical procedures and pyrogen testing or skin temperature measurement during exercise physiology studies.

Supplier: Invitrogen

Addition of sulfuric acid stop solution changes the color to yellow, enabling accurate measurement of the intensity at 450nm using a spectrophotometer or plate reader. This particular formulation is used in most of the Thermo Scientific Pierce ELISA Kits where it provides consistent performance for the sandwich ELISA technique.

Supplier: CHEMetrics

Kit K-9203 comes in a cardboard box and contains everything needed to perform 30 tests: thirty ampoules, acidifier solution, activator powder, 25 ml sample cup, ampoule blank, and instructions. This kit requires the use of a CHEMetrics direct-readout Photometer or a spectrophotometer capable of accepting a 13 mm diameter round cell. Instrument sold separately.

Supplier: CHEMetrics

This kit requires the use of the V-2000 or V-3000 Photometer, an A-2024 SAM Photometer, or a spectrophotometer capable of accepting a 13 mm diameter round cell. Instrument sold separately. This test kit can be used to measure the concentration of ammonia in seawater or saltwater by using the A-1503 Accessory Solution Pack (sold separately).

Supplier: AGILENT TECHNOLOGIES, INC (CSD)

Deuterium and Visible source lamps provide good stability and intensity over the wavelength range.

Supplier: CHEMetrics

Vacu-vials Kits require the use of the V-2000 Photometer or a spectrophotometer capable of accepting a 13 mm diameter round cell. Instrument sold separately. Although the test kit contains 30 ampoules, a fresh reagent ampoule blank must be prepared for each series of tests; therefore, the number of samples that can be tested with each kit will vary from a maximum of 29 to a minimum of 15.

Stop Solution is 0.16M sulfuric acid for use with the ELISA substrate 3,3’,5,5’ - tetramethylbenzidine (TMB). In the presence of horseradish peroxidase (HRP) enzyme conjugates, TMB and peroxide react to produce a blue byproduct having maximum absorbance at 605nm. The color intensity is proportional to the amount of HRP activity, which in turn is related to the levels of target analyte in an optimized ELISA procedure. Addition of sulfuric acid stop solution changes the color to yellow (absorbance maximum at 450nm), stabilizing the color development to enable accurate measurement of the intensity at 450nm using a spectrophotometer or plate reader.
