Common calibration values are olor-coded for ease of use
Choose from pint-size or portable 60-mL bottles
Traceable to NIST standards
Thermo Scientific Orion pH buffers are available in 475-mL (pint) bottles and in portable 5 x 60 mL convenience packs. Portable pH buffers are easier to carry than larger bottles, minimize wasted buffer, and provide more volume than pouches.
Each buffer is color-coded for easy identification and packaged with buffer/temperature tables for accurate calibrations. Buffers are standardized against NIST-traceable pH references for superior accuracy.
