Ryvex LLC has always maintained a very high standard when it comes to analyzing enzymatic and chemical activity in body fluids and blood. As shown in our product portfolio we offer only the market leaders such as:


FUJIFILM is a pioneer in diagnostic imaging and information systems for healthcare facilities and also provides Point-of-Care Testing products for healthcare providers who need immediate clinical test result.

The DRI-CHEM NX700, is a complete bench top Dry Chemistry analyser which can perform multiple test parameters of clinical chemistry and has earned a remarkable reputation from its continuous effort to provide a quick turnaround time, high level of accuracy and long shelf life for reagents.

It can be operated intuitively, thus it is usable to anybody. Moreover, its compact design allows
flexibility in installation.

The Technology behind Fujifilm Dri-Chem Nx700 gives this system the advantage over any other analyser in its class, some of the features that can be seen are:

  • Dry Chemistry completely eliminates the need for a costly water purification system and filters. The analyser does not consume any liquid reagents making it more cost efficient for waste management.
  • The FujifilmNX700 is completely easy to use with real time tutorials that make it easier on the user to remember how to operate and does not require highly trained staff.
  • Practically maintenance free, with this system you can eliminate the cost of maintaining or calibrating the system especially if it is not in use everyday. The system Calibration data is stored on the reagent Calibration card so before each Lot Calibration the card is scanned and the machine is ready to use.
  • Being a dry chemistry system each reagent is made on a dry slide which allows the shelf life to be longer than wet reagents in solutions and storage space is much smallerand easier.
  • Complete test portfolio. The FujiFilmNx 700 has a complete test profile including all General, Enzymatic and Electrolytes tests. Most importantly the Electrolytes are developed using the dry slide technology, each slide is individually packaged and ready to use eliminating the need for costly electrodes.
  • Small Footprint,the FujiFilm Nx700 has an extremely small footprint, about the size of two standard micropipettes, making it ideal for a bench top that’s already short on space.


Apart from all the above mentioned features, this system is completely integratable to an LIS, and has a powerful QC monitoring system that can generate and auto-calculate Levy-Jennings charts, which allows the user to track the system and reagent performance easily. Also as an added benefit, the system can toggle between Human and Veterinary Tests. However the appropriate test kits and reagents are required.

Envoy 500+

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 your lab 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. Plus, the Envoy 500+ is backed by the best service and support in the industry.


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 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 prevents 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 infared 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 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 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 longer walk-away time than a system using disposable cuvettes, which requires you to return to the instrument to reload cuvettes on a regular basis.
