The Futureponics pH 7.00 buffer solutions are supplied in opaque, white, plastic bottles to avoid UV deterioration and each batch is certified and calibrated to NIST traceable international standards to ensure quality and accuracy. All solutions show a batch number, an expiry date, and the correlation between pH and temperature. A certificate of analysis is available on request.
To correctly maintain your meter, we highly recommend using a buffer solution for maximum performance. pH4, along with pH7, can also be used as an emergency storage solution. Buffer solutions should be stored at 25◦C, away from direct sunlight.
