Novel Research Tool measures pH of very small Biological samples

A micro pH electrode has been developed which can measure samples as
small as 5 microliters which is less than 1/10 the volume of a single
drop of liquid. It can also measure small biological specimens down to
less than 0.5 mm in length.

The electrode fits directly into 96 well plates, microcentrifuge tubes,
serum cups, capillary tubes, and NMR tubes.

Biological specimens which can be measured include various animal and
plant tissues. Surface pH measurements on biological samples can also be
made.

The probe is all solid state with a fluoropolymer body making it
virtually unbreakable.  It has a 1 mm tip and 2 mm body and can be used
with any standard pH meter or strip chart recorder.

Micro probes are also available to measure ions such as Na, Cl, and K as
well as pO2 and pCO2.
