RBC Lysis Buffer (10X) is a concentrated ammonium chloride-based lysing reagent.

Supplier: Stemcell Technologies

Ammonium chloride solution is recommended for the lysis of red blood cells (RBCs) in preparations of human and mouse peripheral blood, spleen or bone marrow cells. It is buffered and optimised for gentle lysis of erythrocytes, with minimal effect on leukocytes. It does not contain a fixative agent, therefore leukocytes are viable following RBC lysis.

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.
