PBS buffer tablets (pH7.4 - 1L)

ready-to-use PBS buffer tablets. Each tablet dissolved in 1000mL of deionized water yields: 0.01M Phosphate buffer, 0.0027M KCl, 0.14M NaCl, pH7.4 at 25°C. No time consuming weighing or measuring of pH necessary anymore. You can get rid of the whole validation process and you will have no need for scales or pH-meters anymore.

Amoung biological buffers PBS is one of the most commonly used. The buffer is isotonic and non-toxic to cells and has the ability to maintain their osmolarity. Thereby the buffer is suitable for washing procedures in cell cultures and for immunoassays such as ELISA and immuno-histochemical procedures. It is often used for sample dilution in molecular biology and as protein diluent in Western blotting. Furthermore, the buffer can function as an equilibrator for gel filter columns.

Our PBS is specifically developed for immunological and microbiological laboratories. It is provided as pre-weighed tablets in containers and in convenient blister packs, or as pre-weighed powder mix in sealed pouches. There are different standard-sized packages and final volumes range from 100mL to 100 litres. Choose from different pH (7.2 or 7.4), from PBS with our without potassium, or with and without Tween®.
