  • Easy result administration

The QUANTOFIX® Relax is a revolutionary step in test strip analysis. With this new system, MACHEREY-NAGEL offers an entirely objective way to read QUANTOFIX® test strips, making the system particularly suitable if results are critical to your decision making. The system simplifies testing procedures and the decision processes by eliminating the subjectivity of visual readings and by providing higher accuracy. Especially if you test large numbers of strips, the QUANTOFIX® Relax helps and supports you with easy data administration and quick testing procedures. Additionally, the QUANTOFIX® Relax allows you to get actual quantitative results – no gradation and estimation of in-between values is necessary.
The QUANTOFIX® Relax can change the way you work and test. The system enables you to focus on your core processes and is the perfect tool for your testing procedures.

Optimized usability

Auto start
Select the test, dip the strip and place it on the instrument. Without pressing any further button, the instrument starts the measurement automatically. So, operating is clean and easy.
Graphic display
The graphic display shows all relevant information at a glance. The result is given with a test specific confidential interval. Thus, you can easily decide which further steps are needed for your process.
Touch screen
The touch screen makes using the instrument a real pleasure. All functions are easily accessed with a dip on the screen. You can also enter sample IDs with the on-screen keypad or an external keyboard. This makes documentation of results safe and easy.
Interface options
The instrument features a USB as well as an RS232 interface. It can easily be connected to existing laboratory information systems and also to PCs.
The result is printed using a fast and silent internal printer. Thus, you can easily staple the results to production files for later check or QC procedures.
Easily change tests
With just two dips on the screen you can quickly change between your favorite tests. Select five different tests as your favorites out of a large variety of tests programmed into the instrument. All information is already programmed so you can immediately start the measurement when needed.
Memory for 200 measurements
Up to 200 measurements can be stored. Using internal functions, positive readings are easily filtered out, enabling further diagnosis whenever necessary.
