Test strips, sulphite, MQuant®, Supelco®

Catalog Number: (1.10013.0001)
Supplier: Merck
Description: MQuant® (MQ) test strips can be considered as a mobile laboratory on a few square millimeters of plastic strip. As a screening method they provide the user with a rapid overview of the situation, which helps in making the choice of what, and perhaps if, further analysis is required, thereby leading to potentially substantial savings in time and analytical resources. The strip is a biologically-degradable polyester foil and the low reagent content, in the reaction zones, assists problem-free waste disposal.

Cuvette tests for water testing for WTW spectrophotometers and photometers

Supplier: WTW
Description: A wide choice of tests is available, for routine quantitative analysis in different applications, designed for use with WTW spectrophotometers and photometers. The test is automatically recognised by the laboratory instruments (via a barcoding system) and results are displayed in the appropriate units. Due to the different photometer optics, one test may yield different measuring ranges in different instruments; LED photometers may have smaller measuring ranges for the same test.
