Micro Ion Electrodes

After the success of the Lazar micro pH electrode, Lazar Research Laboratories, Inc. developed a series of micro ion electrodes which are used today by research centers worldwide. Our micro ion electrodes measure ions down to 10 micro liters.

Limited time only! FREE digital millivolt meter with purchase of micro electrode Full Details


Features:
  • High Sensitivity: Most ions can be measured to below 1 ppm. Some ions such as copper (+2) can be measured down to the low part per billion range.
  • Fast response time: Due to membrane design parameters ion selective have a rapid response to changing ionic concentration. Response time of 30 seconds is typical.
  • Broad concentration range: Electrodes will detect ions down to the low part per million range up to several thousand ppm. Some of the electrodes will measure up to a concentration of 1 Molar.
  • Resistant Body: Makes electrodes usable in acids, bases and some solvents.
  • Portable: On-the-spot field measurements can be made without a trip back to the laboratory.
  • Small Samples: Measures samples as small as 10 micro liters.
  • Quick and Simple Readings: The electrodes can be used with any portable or laboratory pH/millivolt meter.
  • Direct Plug: Our electrodes plug directly into your pH/millivolt meter. No compatibility problems.
  • Some micro ion electrodes also available for NMR tubes - see below

    Best buy! Complete micro ion measurement systems measure, log & graph all in one!

    You can now purchase ion electrodes as a complete measurement system which measures, logs and graphs all-in-one. System includes meter, ion electrode, our exclusive PC plotting software and more.

    See ion systems index for features and advantages of our complete ion systems.
    Pricing and specifications for both electrodes and complete systems are below.

    Electrodes below with "*" are mono electrodes which require a micro reference electrode which is included in the price of the electrode (save $100 when purchasing reference electrode together with electrode). All other electrodes are combination electrodes where reference electrodes are already built in.
