PBS appears as white instant granules. Each pouch makes 1 L of 1× PBS solution conveniently with a simple procedure. PBS is composed of NaCl, KCl and phosphate. 1× PBS contains 137 mM NaCl, 2.7 mM KCl and 10 mM phosphate.
       PBS buffer is the most widely used buffer in biology labs. It is used in immunoassays, microbial experiments and protein biochemical experiments.The PBS buffer prepared with PBS instant granules can be used in cell culture, washing and other related experiments after being treated with 0.22 μm sterilization filter.
Note: All related raw materials are AR / GR grade.

Note: pH is 7.4±0.2@25℃ when made to 1× solution.

1. Put magnetic stirring beads and ~600 ml distilled water into a beaker.
2. While stirring, slowly pour the whole contents from 1 pouch of PBS into the beaker; wait until everything is dissolved.
3. Add distilled water to bring the volume to 1 L and 1× solution is made.
