Lab-quality results, automated and economical

Lab-quality results

The OPTI LION Electrolyte Analyzer provides lab-quality results with zero standby cost. The single-use consumable is only used during a measurement and safely locks waste inside.

Low maintenance

The innovative optical fluorescence technology of the OPTI LION analyzer eliminates electrodes, and its unique sensor construction prevents lipid/protein build-up. In addition, the single-use cassette does not require a fluidics system, eliminating tubing maintenance.

Reusable controls

The OPTI LION analyzer has reusable quality-control cassettes to eliminate the cost associated with performing daily liquid quality control.

Measured pH and ionized calcium along with sodium, potassium and chloride

The OPTI LION analyzer measures pH and ionized calcium in the same single-use cartridge that also measures sodium, potassium and chloride simultaneously, providing a more complete picture of the patient’s status.


Principles of operation

The OPTI LION Electrolyte Analyzer is a microprocessor-based instrument that measures optical fluorescence from discreet sensors called optical electrodes (optodes). A disposable, single-use cassette contains all of the elements needed for calibration, sample measurement and waste containment.

Calibration information is loaded into the analyzer automatically when a cassette is read using the bar-code reader. The analyzer performs a calibration verification on all sensors before aspirating the sample into the disposable cassette. The sample is moved across the optode sensors and the fluorescence emission is measured, giving you a reliable reading of the tests you have selected.

OPTI LION single-use cassettes include these features:
  • Calibration of cassette before sampling—avoids sample loss
  • Test parameters—Na+, K+, Cl–, Ca++ and pH
  • Safe disposal—waste is stored in cassette
  • Maintenance-free operation—no electrodes
  • Zero standby cost—no reagents required

How to use

Simple and easy to use

The OPTI LION Electrolyte Analyzer is easy to run:
  • The user-friendly touch screen, with simple menu navigation, can be used with minimal training.
  • Automated sample aspiration reduces preanalytical errors and training.
  • Measuring pH allows for a measured and normalized ionized calcium.

1. Scan the cassette bar code.

2. Open the cassette packaging and place the cassette into the sample measurement chamber and close the cover.

3. Attach the aspirating tube.

4. Aspirate the sample. When sample aspiration and measurement is complete, the results will automatically appear on the screen.
