Technical Details

The intuitive software guides users step-by-step through a simple measurement workflow. After brief training in pipetting and measurement handling, anyone can operate the system confidently — no chemical background required. Sensors arrive factory-calibrated, eliminating time-consuming calibration procedures.
Optical measurement techniques typically require centrifugation or filtration when samples are turbid, adding processing time and increasing the risk of handling errors. In addition, colored sample components can interfere with optical signals and compromise measurement accuracy. The DirectSens® system combines enzyme specificity with robust electrochemical detection, enabling precise and reliable glucose quantification directly in turbid or colored samples — without sample preparation. Our technology streamlines analysis also in protein-rich or fat-containing samples, eliminating the need for Carrez clarification or fat separation steps.
No laboratory environment or specialized personnel are required. Measurements can be performed wherever space is available for dilution and testing, provided the ambient temperature is between 20–24 °C (68–75 °F). This enables faster process control and eliminates sample transport delays. .
The measurement takes about two minutes — delivering rapid insights for real-time decision making.
Each system includes everything required for reliable, traceable performance verification with electronic reporting:
  • Measurement Performance Check: Every DirectSens® Biosensor Kit includes a Control Solution for QC validation.
  • Reader Performance Check:The reader kit includes an electronic Testing Device for a quick functionality check-up (approx. 3 minutes).
    • The reader requires no routine maintenance. If liquid enters the biosensor slot, the front module can be replaced easily with a simple one-screw exchange.
    Measurement data can be exported as XLS, CSV, and PDF reports. CSV format enables direct import into LIMS environments for streamlined documentation and compliance workflows.
    Directly sync results with your existing Laboratory Information Management System via secure API.
    Compact dimensions (21x15cm) save valuable bench space in crowded laboratory environments.
    IP65-rated housing protects internal electronics from dust, moisture, and accidental impacts.
    24/7 access to our global team of application specialists and technical engineers.
    Fully compliant with ISO 9001 and CE marking requirements for industrial instrumentation.
    Significant reduction in per-test costs compared to traditional laboratory outsourcing.

    Creamy Fondant Fillings in Chocolate and Sugar Confectionery

    In the chocolate and sugar-confectionery industry, creamy fondant fillings are produced from a firm sucrose paste that becomes soft over time through the action of invertase. After chocolate coating, the enzyme gradually converts sucrose into glucose and fructose, creating the desired smooth texture.

    The DirectSens® Glucose Biosensor Kit enables accurate on-site measurement directly in the production environment. Samples no longer need to be transported to a laboratory.

    Key Advantages:

    Reliable texture control
    On-site measurements
    Consistent batch quality

    Invert Sugar Production

    Invert sugar is produced through enzymatic or acid-catalyzed conversion of sucrose into glucose and fructose. For process optimization and consistent quality control an accurate monitoring of glucose concentration is needed.

    The DirectSens® Glucose Biosensor Kit provides immediate on-site process control without the need for laboratory infrastructure.

    Key Advantages:

    Precise process control
    Directly at the production site
    No chemical expertise required

    Brewing non-alcoholic beer

    When producing alcohol-free beer using maltose-negative yeast strains, precise control of fermentation parameters is essential. Monitoring glucose concentration helps to forecast the final alcohol concentration.

    The DirectSens® Glucose Biosensor Kit enables fast, reliable measurements directly in the brewery environment.

    Key Advantages:

    Precise glucose results
    Rapid on-site measurements
    Full process control
