Labchem pH Buffers

Choose from a Variety of Strengths and Sizes

All pH meters require calibration with a Buffer solution before use. These color-coded Buffers are traceable to NIST and accurate to pH 0.01 at 25°C. The 500mL poly bottle is a handy option for field use while the 4L poly bottle and 20L CubitainerŽ are great for laboratory use.
