Cole-Parmer Thermo Scientific 910104 pH Buffer Solution, 4.01, Pink; 475 mL Bottle
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.
