Cole Parmer - Buffer Solution

Cole Parmer - Oakton® pH Buffer Solution

Cole-parmer pH buffers are compared against and are traceable to NIST standard reference materials. Each bottle includes a nist-traceable calibration report supplied by the manufacturer. Color-coded and colorless buffers are available in 500-mL, 1-l, or 4-l packaging sizes. Additional values and packaging sizes are available; . Store at room temperature. Nist-traceable reference materials include a calibration report from an ISO guide 34 and ISO 17025 accredited laboratory color-coded and colorless buffers available.

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!
