Thanks to ALL !

The answer lies somewhere between 10 and 50 per ml
with a mean at 20.

Making a self experiment is not so easy with costly
and/or dangerous products...

I just would like to improve on Ca titration using
a serynge marked 0 to 200 (= 2ml)...

Dear all,

Does anyone has an idea ?
is it really constant (when no viscosity is present) ?
Or does it depend of the hole size ?
