PBS (Phosphate Buffered Saline) tablets are prepared from ultra pure grade chemicals and thoroughly blended to homogeneity. Each PBS (Phosphate Buffered Saline) tablet contains 137 mM NaCl, 10 mM phosphate buffer, 2.7 mM KCl, with a pH of 7.4 (+/- 0.1). The PBS tablets are designed to dissolve readily, usually within 3 minutes of stirring. One tablet prepares 100 mL of PBS and higher concentrations can be obtained by dissolving 2, 3 or 4 tablets per 100 mL of water. PBS is a water-based salt solution that helps maintain a constant pH. PBS is isotonic and non-toxic to most cells so therefore has many uses, including substance dilution and cell container rinsing.
