- Ideal for laboratory and field analysis
- All Oakton pH buffers are traceable to NIST standard reference materials
Buffer solution lets you calibrate pH instruments to ensure accuracy
If unopened, shelf life is 2 years - USA buffer value of pH 7.00
• Oakton pH Buffer Solutions have pH/temperature tables printed on the labels for accurate calibrations (not on 60-mL, but included as insert)
• Manufactured under ISO 9000 quality guidelines and traceable to NIST standards
• If unopened, shelf life is 2 years; once opened, use pH 4 and pH 7 within 90 days, pH 10 within 30 days
• Buffer Options:
- pH 1.68 buffer available in clear
- pH 4.01 buffer available in red
- pH 6.86 buffer available in clear
- pH 7.00 buffer available in yellow
- pH 9.18 buffer available in clear
- pH 10.01 buffer available in blue
- pH 12.46 buffer available in clear Buffer is colored for quick-glance recognition and does not effect accuracy or stability. As of April 2018, Oakton will be using yellow for the color-reference of the pH 7 buffer solution instead of green.
Standardized against NIST-traceable pH references for meters with 0.01 resolution. Sold as a case of four jugs; 1-gallon bottles are also available individually.
