Description
The Signet pH buffers are ideal for many calibration requirements. The liquid solutions are conveniently packaged in one pint bottles; the powder pillows are packaged in low weight, single-use containers which can be mixed with water. All pH buffers are color coded for easy identification; 4.01 pH is red, 7.00 pH is yellow, and 10.00 pH is blue.
The pH buffers are traceable to NIST standards and certificates are available upon request. They are accurate to within ± 0.01 pH units at 25 degrees C and have long term stability.
These solutions are temperature sensitive and are provided with temperature correction values for the most accurate calibration. For applications that require ORP calibration, the pH 4 and pH 7 buffers can be mixed with quinhydrone powder for the correct measurement values of +87 mV and +264 mV respectively.
Features:
- NIST traceable
- Easily identifiable color coded buffer solutions
- Liquid or powder versions
- Temperature compensated values
- Kits for easy use
