BPB 10

BPB 10 pH Buffer Powder

The BPB 10 pH buffer powders can be used to calibrate pH electrodes. The BPB 10 is supplied at a pH of 10 and are sealed in sachets made of triple protective foil consisting of aluminum, polyethylene and paper which keeps the powder dry, protected, free-flowing and to allow for an exceptional shelf life. The free flowing powder makes 500ml of buffer solution when dissolved in deionised water, meaning a full box is capable of making up to 2.5 litres of calibration solution meaning it can be safely stored until it is required. They are supplied with an indicator to test the pH of the made solution and an inhibitor to inhibit mould growth.

BPB 10 buffer powders produce 500ml of 4.00 pH Buffer Standard solution when dissolved in distilled water.
