VWR®, Total Hardness Indicator, Tablets for Hardness of Water Determinations, Avantor

Supplier: VWR Chemicals

Indicator tablets for determination of water hardness by titration with EDTA.

Specifications
Minimum weight: ≥ 0.20 g
Maximum weight: ≤ 0.23 g
Disintegration time (at 25°C): ≤ 150 s
Application test: conforms

The tablets are dissolved in 100 ml of the water sample to be tested, which has been buffered at pH 10 with 1 ml of Ammonia/ Ammonium chloride buffer solution, and then titrated with EDTA solution (0,01 M) till the sample turns from red to blue.
Total hardness in mg/l = 10×ml of titrant used.

Control samples of calcium carbonate should be used to calibrate the method.

Blank test strips, MQuant®, Supelco®

Supplier: Merck

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.

Spectroquant® PhotoCheck, Supelco®

Supplier: Merck

The PhotoCheck test set is designed for testing the wavelength accuracy of all Merck photometers and spectrophotometers. It can be used as a secondary standard for testing instruments according to DIN/ISO 9000 and ISO 14000. The stable colour solutions can be used to test the following spectrophotometer filters and wavelength settings: 445 and 446 nm, 520 and 525 and 690 nm. The accuracy of the wavelength setting and the linearity of the extinction measurement is checked with four solutions per wavelength. The traceability of these test solutions to international standards is guaranteed by examining them in a reference photometer that is checked against the primary standard (NIST standard). These values are properly documented and supplied as part of the set.
