Benefits

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.
No laboratory environment or specialized personnel are required. Measurements can be performed wherever space is available for dilution and testing, enabling faster process control.
Traceable performance verification with electronic reporting:
  • Measurement Check: Control Solution for QC validation.
  • Reader Check: Electronic Testing Device for check-ups.
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.
Designed for real production environments, the reader features a solid aluminum housing and protective rubber bumpers for long-term reliability.
Manufacturing and quality assurance processes comply with ISO 9001 standards, ensuring consistent product performance and reliability.
Quality control operations often involve hidden costs beyond instrumentation — including labor, maintenance, laboratory infrastructure, and sample logistics. For low to medium throughput applications, the DirectSens® Glucose Biosensor Kit offers a cost-efficient alternative that reduces overall operational expenses.

Interested in a total cost of ownership comparison of a DirectSens® Biosensor solution versus your current glucose measuremnt setup? Contact us to receive a personalized assessment.
Optical measurement techniques typically require centrifugation or filtration when samples are turbid. The DirectSens® system enables precise and reliable glucose quantification directly in turbid or colored samples — without sample preparation.
Following dilution, measurement takes about two minutes — delivering rapid insights for real-time decision making.
The reader requires no routine maintenance. If liquid enters the slot, the front module can be replaced easily with a simple one-screw exchange.
The reader fits into the palm of a hand – therefore it does not occupy valuable lab space. Just take it out of the cupboard when you need it.
We provide expert support to ensure your measurement success, including manuals, application notes, online resources, and technical assistance via email, phone, or online. All services except formal training are provided free of charge.
All measurement liquids are water-based, non-toxic, and non-flammable. After use, solutions can be disposed of via standard drainage. Biosensor test strips can be discarded with regular household waste.

Applications

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.

Precise glucose monitoring at defined time points is essential to ensure consistent product quality across batches. 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, and trained operators without chemical expertise can perform measurements at any time — including night shifts and weekends, when the lab is not in operation.

KEY ADVANTAGES:

Reliable texture control through targeted glucose monitoring
On-site measurements without lab dependency
Consistent batch quality with minimal operational effort

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 or specialized personnel.

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 and provides critical insight into the fermentation progression.

The DirectSens® Glucose Biosensor Kit enables fast, reliable measurements directly in the brewery environment. Combined with the DirectSens® Alcohol Biosensor Kit, brewers gain comprehensive control over fermentation without delays caused by laboratory analysis.

KEY ADVANTAGES:

Precise glucose results for the forecast of final alcohol concentration
Rapid on-site measurements without chemical training
Full process control in combination with the DirectSens® Alcohol Kit

Free Validation Service

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 delay.
Following dilution, 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).
