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.

Hanks' Balanced Salt Solution (HBSS) is a buffer used to maintain a physiological pH for cells maintained in non-CO₂ atmospheric conditions.

Supplier: Stemcell Technologies

Hanks’ Balanced Salt Solution (HBSS) can be used for diluting, washing, irrigating or as a transporting solution for cell or tissue culture. It provides a buffering system to maintain the physiological pH range and osmotic balance of culture media, and provides cells with a source of water and essential inorganic ions and a carbohydrate as an energy source. Selection of suitable nutrient medium is dependent on type of cell, culture conditions, and degree of chemical definition required for the cell culture application.

Supplier: Biowest

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.
