pH Buffer Standards
AURCAL 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 500-mL,1, 4 & 20- liter containers. All screw capped containers include tamper evident double seal caps to prevent leakage and security. A convenience dispensing faucet is available as an extra for the 20-liter cube.. These items are always in stock for prompt shipment. In addition to the routine pH 4, 7 & 10 buffers, Calitech buffers at pH 1, 2, 3, 5, 8, 9, 11 & 12 are available on order. Please tell us what you need. These are made to the same exacting standards as the routine buffers. They are supplied uncolored and are certifiable to NIST Standards.

When ordering please specify level of buffer required. If special level is needed please specify this on order form as this will affect both delivery time and pricing. Also indicate whether buffer needed is to be color coded or clear.
