Product Description
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.
Why Milwaukee M10004B?
±0.01 pH Certified Accuracy: Meets international buffer standards — eliminates errors from powder mixing and delivers traceable, repeatable calibration results.
Single-Use Sachet Packaging: Fresh, uncontaminated solution every use — no risk of expired, degraded, or cross-contaminated buffer.
Sealed Against Light & Air: Preserves solution integrity from production to point of use for maximum reliability.
Color-Coded for Easy Identification: Instantly distinguish pH 4.01 from pH 7.01 and 10.01 buffer solutions at a glance — no mislabeling risk.
5-Year Shelf Life: Long expiry for cost-effective stocking, bulk purchasing, and infrequent-use scenarios.
Field & Lab Ready: Compact sachets are ideal for on-the-spot calibration in greenhouses, field sites, labs, and production facilities.
Extends Electrode Life: Proper calibration with certified buffers protects your electrode investment and maintains long-term measurement accuracy.
25 Sachets Per Box: Generous supply for routine calibration schedules in high-frequency testing environments.
