Spexyte™ Micro pH Probe *Optimized for Nanodrop*

Biological samples are usually in a very narrow pH range from 4.5 to 8.5, and many of them need to be provided in micro-volume (e.g., microliter). It is difficult to measure the pH values with small volumes accurately using the conventional pH meters due to the bulky sizes of the conventional pH electrodes. Spexyte™ Micro pH Probe is optimized to measure µL samples in the range of pH 4.5 ~8.5 using a NanoDrop™ or an equivalent device. The pH value is measured by reading the ratio of BCFL absorbances at 502 nm to 470 nm since the relationship between the pH value and the absorbance ratio (502/470nm) fits the Four-parameter logistic model well. The pH of a microvolume biological solution could be measured quickly and accurately in seconds with Spexyte™ Micro pH Probe. It provides a sensitive, easy and fast method to measure the pH values for micro-volume samples.
