Micro Combination pH Electrode


BEFORE YOU BUY ANOTHER pH ELECTRODE CONSIDER THESE ADVANTAGES

*You can now measure pH in your smallest samples
 Microtiter & terasaki plates-micro test tubes-serum cups-capillary tubes

*Measures pH in 1/10 of a drop.  This electrode enables you to measure
 samples as small as 10 microliters (1/10 of a drop)

*Guaranteed Unbreakable.  Electrode features solid state sensor and
 flouropolymer capillary tube making it virtually unbreakable. Electrode is
 guaranteed against breakage for the life of the probe.  Why settle for
 glass?

*More stable than glass electrodes.  The solid state design of the
probe
 offers a much lower output resistance than glass probes of the same size
 giving a much more stable pH reading.

*Extremely Small Sensor size.  Tip diameter of the Ultra M electrode
is only
 1 mm.

*Low Immersion depth.  Immersion depth for the Ultra M micro
combination
 electrode is 1 mm.  For even lower immersion depths use the PHM-146 micro
 pH mono probe with an immersion depth of 0.1 mm.

*Broad pH range.  The pH range of the Ultra M comb pH probe is 1 to 12.

*Compatible with all laboratory pH meters.  The Ultra M micro comb. pH
 probe is compatible with all major brand pH meters including Orion(R)
 Beckman(R)  Corning(R) Fisher(R) and Radiometer(R).  Specify meter when
 ordering.

*REDOX Measurements.  A micro probe for oxidation-reduction
 measurements is also available.  See ordering information.

*Application Areas
 Biotechnology
 Biological sciences, medicine & physiology
 Pharmaceuticals
 Radioactive samples
 Isoelectric focusing gels
 LC & HPLC
 NMR samples
 Environmental studies

Micro ION Electrodes


COMPARE THESE ADVANTAGES TO THE ION ELECTRODES YOU ARE CURRENTLY USING


*You can now measure common ions in your smallest samples
 microtiter plates r-serum cups-HPLC sample vials-micro test tubes

*Measure common ions in 1/10 of a drop of liquid.
 ***These electrodes are the smallest available anywhere.***

Virtually unbreakable. electrodes feature fluoropolymer
bodies with solid
 state sensors, making them virtually unbreakable.

Fast, stable response. Response time is typically 30 seconds or less
 making them much faster than liquid membrane electrodes.

Low Detection limit. All micro ion electrodes will measure down to
 1 ppm, (parts per million), some electrodes like the sodium probe will
 measure down to 0.02 ppm.

Low Immersion depth. Immersion depth for the ion probes is only
 0.1 mm.
