pH microelectrode: modified Thomas recessed-tip configuration.
Through the use of a glass-membrane pH electrode and a water-tight seal a modified Thomas pH microelectrode has been developed. The modified Thomas electrode has a relatively low electrical resistance (10(11) omega), a small sensing chamber (10 microns3), and a rapid response time (10 s) and can be manufactured in both single- and double-barreled configurations. The modified Thomas electrode is designed to measure the intracellular pH of small cells such as those found in the mammalian kidney tubule.
