Measure pH of micro bio samples

I found the electrode useful in measuring micro bio samples
in 96 well plates where a standard size pH electrode
could not fit into the well. I used the micro pH electrode
with my standard lab pH meter and pH 7 buffer.

You can get further details by going to the following
