pH Calibrating Buffers In Single Use Pouches - Each Pouch is a fresh container Traditional Formulations pH 4, 7 & 10, color coded. Calitech pH calibrating buffers are formulated with NIST specified ingredients including EPA registered broad-spectrum antimicrobials to assure long-life free of mold and bacterial growth. These are color coded for easy recognition. Accuracy is referenced to NIST Standard Reference Materials ±0.01 pH @ 25°C for routine buffers and ±0.002/0.005 @ 25°C for high-accuracy buffers. Traceability certificates are furnished on request. The buffers are packed in 20-mL single use pouches. Accuracy as referenced to NIST Standard Reference Materials or NIST method is ±1.0% @25°C.
