Hanna Instruments HI70009 pH 9.18 Solution 25x20 mL sachets

If you take measurements in alkaline environments, now you can use buffer solutions at pH 9.18 in addition to pH 10 buffers.

This means better accuracy and versatility, especially with HANNA® microprocessor pH meters, which can be calibrated at both pH 9.18 and pH 10.

All pH 9.18 solutions show the batch number, the expiration date and have a pH/temperature correlation table on each bottle.

HI 5091, HI 6091, HI 70009C, HI 7009L/C & HI 8009L/C are provided with a certificate of analysis.
