Milwaukee M10004B pH 4.01 Buffer Solution – 20 mL Sachets, Box of 25
Calibrate with confidence using Milwaukee M10004B — a certified, lab-grade pH 4.01 buffer solution packaged in convenient single-use 20 mL sachets. Engineered for pH meters, testers, and electrodes used in hydroponics, aquaculture, water treatment, food & beverage, pharmaceutical, and laboratory environments.
Each sachet delivers ±0.01 pH certified accuracy, eliminating the guesswork and contamination risk of powder-mixed buffers. Simply open, insert your electrode, and calibrate — fresh, traceable solution every single time. With a 5-year shelf life, the M10004B is the smart choice for both high-frequency labs and infrequent field use.
