Product

DK digestors feature an aluminum heating block, providing uniform heat distribution and rapid heating up to 450°C.

Continuous microprocessor control allows for precise temperature regulation with an accuracy of ±0.5°C, ensuring high reproducibility and reliable results.

Thanks to optimized energy consumption, these digestors reduce power usage by 13%, which leads to lower operational costs and reduced CO2 emissions.

Additionally, DK 6 and DK 20 are compatible with COD analysis, enabling Chemical Oxygen Demand (COD) determination with the use of additional glassware support systems.

Precise Thermal Digestion with Minimal Losses

The DK digestors are designed to maximize laboratory space efficiency, providing:

  • Optimized use in labs with limited space
  • Easy integration under laboratory fume hoods
  • Protective grid to shield the heating block from chemical spills
  • Stainless steel construction resistant to chemicals

The ergonomic digital display ensures clear visibility and easy operation, offering:

  • Up to 20 programmable methods with 4 temperature phases
  • Acoustic signals to notify the end of analysis
  • Protective front panel shielding from chemicals and heat

Compact Design for Efficient Laboratory Use

DK digestors provide maximum efficiency with lower operating costs, due to:

  • Optimized energy consumption, reducing resource usage
  • Physical and chemical filters to remove water vapor, extending the instrument’s lifespan
  • Automated processes, minimizing human intervention and increasing safety

For applications involving corrosive or acidic fumes, DK digestors are compatible with the KS 1000 Scrubber system, which effectively neutralizes harmful emissions.

With DK digestors, laboratories benefit from a long-lasting, cost-effective, and precise solution for routine Kjeldahl analyses, featuring user-friendly operation and minimal maintenance.
