ENVOY 500+

High throughput benchtop chemistry analyzer. With the Envoy® 500+, you receive test results faster than with almost any other bench-top chemistry system on the market, allowing  you to make your treatment decisions sooner. The Envoy 500+ performs approximately 490 tests per hour, allowing it to handle the workload of the busiest labs.  The Envoy 500+ delivers the time and money-saving features the laboratory requires with an integrated four-parameter dry ISE module, reusable glass cuvettes, positive sample and reagent identification, clot detection, liquid level sensing, and many more.

  • 20-80 patients per day
  • 40 refrigerated reagent positions
  • 52 patient position sample wheel
  • Clot detection sensor
  • Reusable glass cuvettes
  • Dry Electrodes

ENVOY 500+


Accurate results and proper treatment decisions.

  • Clot and liquid sensor detection prevent reporting of invalid results from insufficient and difficult samples.

Longer walk-away time.

  • The reusable glass cuvettes provide your lab with longer walk-away time than a system using disposable cuvettes, which requires you to return to the instrument to reload cuvettes regularly.

Reduced reagent consumption and costs.

  • Dry Electrodes of the Envoy 500+ have a permanent gel that limits routine priming with ISE reference solutions. Because they can be left dry when not in use, it reduces reagent consumption and costs.

The Envoy® 500+ uses its own line of reagents that are manufactured, validated and optimized by VitalScientific.

  • This ensures quality results, maximum performance, and the highest value.
  • The Envoy 500+reagents also feature barcoded labels, allowing the Envoy to identify each reagent.

Touch Screen The Envoy® 500+ has a built-in LCD touch screen and is driven by the Windows® operating system. This provides greater ease of use and space savings by eliminating a bulky external monitor and CPU. Quality Control Quality Control results are stored in memory and easily displayed on the screen. QC can be evaluated using up to six Westgard rules and displayed with either the theoretical or calculated means. Pre-Programmed Parameters The Envoy reagent application parameters are pre-loaded into the software, saving you time and eliminating the possibility of data entry mistakes.

Reagent Handling

Large Capacity The Envoy 500+ holds up to 40 individual Envoy reagents (mono or dual), providing a longer walk-away operation. Refrigerated Reagent Tray Onboard refrigeration and storage ensures reagent stability, which increases the reliability of results while lowering laboratory costs. Continuous Inventory Monitoring Continuous inventory monitoring enables the operator to know the number of tests remaining for each reagent, minimizing waste. Positive Reagent Identification The reagent chamber contains an infrared barcode scanner capable of scanning Envoy barcoded reagents, automatically recognizing reagent position and lot information.

Sample Handling

Sample Wheel The Envoy 500+ sample wheel has 52 positions available for patient samples and 26 for calibrators and controls providing your laboratory high throughput capability. Primary tubes or sample cups can be used, providing the testing flexibility you need. Clot Detection and Liquid Level Sensing Clot detection and Liquid level sensing prevent reporting of invalid results from an insufficient or difficult sample. This ensures accurate results and proper treatment decisions. Positive Sample Identification The sample chamber contains an infrared barcode scanner, capable of scanning your patient barcodes, eliminating the need to manually enter patient information and reducing the risk of sample errors that can cost you time and money.


Dry Electrodes The Envoy 500+ utilizes a proven, dry, solid-state ISE (Ion ion-selective electrode) that can be kept dry when not in use thus reducing reagent consumption. Four Parameters The ISE system has four electrodes, Na+, K+, Cl-, and CO2, providing a complete test panel without adding an enzymatic procedure or using a traditional ‘wet’ electrode. This significantly reduces costs and maintenance time, while increasing the reliability of results.

Reaction Cuvettes

Glass Cuvettes The Envoy 500+ contains 34 reusable glass cuvettes that are automatically washed on board, which eliminates the cost of expensive disposable cuvettes. Increased Walk-away Time The reusable glass cuvettes also provide your lab with longer walk-away time than a system using disposable cuvettes, which requires you to return to the instrument to reload cuvettes regularly.
