High Accuracy pH Buffer Standards

pH 4, 7 & 10, color coded, and High Accuracy

High Accuracy Buffers pH 4, 7 & 10 ±0.002 @ 25°C vs. NIST SRMs

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 0.002/0.005 @ 25°C for high-accuracy buffers. Traceability certificates are furnished on request. The buffers are packed in 500-mL,containers. All screw capped containers include tamper evident double seal caps to prevent leakage and security.
