Buffers and Standards:

pH buffers or hydrogen ion buffers are buffer solutions that allow you to adjust your testing system to precisely measure your samples’ unknown pH. Our selection of pH value buffers and pH solution packs can help you feel more confident about accuracies. For best accuracy make sure you perform standardization with fresh buffer solution. Never pour used buffer back into the bottle. Always discard buffer solution after use. Use buffers that frame the pH range of the samples you are testing; match the temperature of the buffer to the temperature of the samples. Calibrate your system before each use or set of uses. We even have buffer pouches to keep your accuracy when you're on the go!
