Dear AMMRL members,
I have some samples where I would like to measure both the pH and
osmolality. We have an old battery operated pH meter (Fisher Scientific)
with a small electrode (Aldrich) that would fit into a 5mm NMR tube but it
is very finicky. Can someone suggest an osmometer that can be used on
small volumes. Ideally, I would like to find a meter that is capable of
measuring both the pH and osmolality (having to change probe is okay) for
small volumes ie less than 500uL.
Sincerely,
Que Van
