3. Product Application

pH regulatorDipotassium hydrogen phosphate has been used in the preparation of potassium phosphate buffer for the resuspension of polyelectrolyte capsules, and can also be used as a buffer in the determination of glutaminase. The phosphate buffer system is the most widely used buffer system in biochemical research and has the following advantages:

1) easy to prepare into various concentrations of buffer;

2) The applicable pH range is wide;

3)pH is less affected by temperature;

4) After buffer dilutionThe change of pH is small, such as the change of pH after ten times dilution is less than 0.1.

4. Characteristic R & D service

1. National Pharmacopoeia Detection Operation Decomposition Guidance

2. Customized specialty preparation services
