Our micro dissolved oxygen electrode can be used to measure
dissolved oxygen of tissues, whole
cells, cell fractions, and various types of respiration studies. It
can also be used to measure dissolved oxygen in biological and
environmental samples. The micro DO electrode has a 2mm tip and a 6mm
The micro dissolved oxygen electrode is now available as a complete
system which measures, plots and graphs all-in-one. Complete system
includes micro dissolved oxygen probe, amplifier, dissolved oxygen
monitor and software which logs and plots directly to your PC. See
DO systems index for full further information.
Measure pO2 in your smallest samples
Measure samples in -
96 well plates
micro test tubes serum cups
NMR tubes-microcentrifuge tubes
Measure samples as small as 20 microliters which is less
than 1/4 the size of an average drop of liquid.
Use with any pH meterThe micro pO2 electrode utilizes a
self contained amplifier circuit which makes it useable with
any standard pH/mV meter for dissolved oxygen measurements.
The pO2 electrode can be plugged directly into any pH meter
and is available with all standard pH meter connectors
including BNC, U.S. standard, Radiometer(R), and Metrohm (R).
Use with chart recorder Output voltage of 0 to 2 volts DC
allows connection to any standard chart recorder for
continuous monitoring of pO2 level.
Porlarographic Principle The pO2 electrode works on
polarographic principle where oxygen is reduced at a tiny
cathode sensor which is covered with a semipermeable membrane.
Extremely small sensor size Tip diameter of the micro pO2
electrode is only 2 mm.
Low immersion depthImmersion depth for the micro p02 electrode
is less than 1 mm.
Calibrate in convenient unitsThe micro pO2 probe can be
calibrated in mm Hg pO2 partial pressure, % oxygen, or ppm
Broad pO2 concentration range The micro pO2 has a range from
0 to 100% oxygen or 0 to 760 mm Hg pO2 partial pressure.
Low O2 detection limit The micro pO2 has a detection limit of
1 mm Hg pO2 partial pressure.
Broad temperature range Temperature range is 0 to 60 oC.
