Preparation of MOPS(cas 1132-61-2) physiological saline solution

The preparation of MOPS(cas 1132-61-2) physiological saline solution should pay attention to the interaction of various ions. Generally should be prepared before the experiment, and should not be placed too long, so as to avoid pollution or some chemical changes in the composition of the experimental results, or the first solution of the various ingredients were prepared into a certain concentration of the base solution, preparation of base fluid. In the preparation of various physiological salt solution should pay attention to the following points:

1. Because of the physiological salt solution of phosphate and carbonate anion easily react with calcium ions, resulting in insoluble white calcium phosphate or calcium carbonate precipitation. Therefore, in the preparation of physiological salt solution, the first other liquid stock solution and add distilled water, and finally dissolved calcium chloride solution while stirring slowly to prevent calcium salt precipitation generated.

2. Glucose should be added at the time of application, add the physiological saline solution of glucose can not be set for a long time, so as to avoid bacterial contamination occurs turbidity.
