These irrigating buffers and salt solutions are sterile, physiological balanced solutions intended for use in the maintenance of mammalian cells, where a chemically defined, balanced salt solution provides an environment that will maintain the structural and physiological integrity of cells in vitro. Applications include the intermediate steps for cultivation of cells, like washing, centrifugation, suspending and counting, as well as for many analytical methods or biochemical treatments. Principally these solutions should be used to keep the cells in suspension only for minutes or a few hours maximum. These buffers and solutions are not cell culture media.

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.

Supplier: Avantor

pH Buffer solution, colour coded, Phthalate, pH value: 4,00, ±0,01, Reference temperature: 25 °C, Specpure®, Red, Bottle

Supplier: MP Biomedicals

Soluble in distilled water. Soluble in 0,1 M potassium phosphate buffer, pH 6,0 (monobasic potassium phosphate adjusted to pH 6,0 with 1,0 M potassium hydroxide) (10 mg/ml yields a clear, red-brown solution). Solutions of HRP can be kept refrigerated for up to a year while maintaining practically undiminished activity. Optimal pH is 6,0 to 6,5 (activity at pH 7,5 is 84% of the maximum). The enzyme is most stable in the pH range of 5,0 to 9,0 (Lit.).
