This loading dye base is used for custom loading buffer preparation. It is a concentrated solution containing patent blue, bromophenol blue and amaranth tracking dyes, which migrate at approximately 4 000, 400 and 10 bp, on a 1% agarose gel, respectively.

Supplier: REAGECON

Colour coded pH buffer solutions for the calibration of pH meters.

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.

Chloronaphthol (4-CN) is a peroxidase substrate used for chromogenic detection of HRP in immunoblotting and immunohistochemical applications. This product is less sensitive than other precipitating substrates, but the distinct blue to blue-purple precipitate photographs well and can be useful in double-staining applications. The coloured product is soluble in alcohol and xylenes, but is not soluble in aqueous buffers. The 1-Step Chloronaphthol is supplied ready to use.

Supplier: Thermo Orion

Fluoride standards are pre-made with total ionic strength adjustor buffer (TISAB) and requiring the TISAB be added only to your samples.
