The Kjeldahl method KjelDigester reduces the block digestion process by up to two hours and meets the highest safety requirements. The high degree of automation is the perfect match to the KjelMaster System allowing for unprecedented sample throughput. Applications includes classical Kjeldahl tasks such as TKN (Total Kjeldahl Nitrogen) or Devarda as well as the direct distillation of other volatile components such as alcohol, sulfur dioxide …

  • Acceleration of the heating and cooling step, saving up to two hours
  • Direct transfer of the 20 position rack to the KjelSampler
  • Unattended operation by using automatic lift and delayed start time (K-449 only)
  • Programmable time / temperature profiles and full Scrubber K-415 control (K-449 only)

Available Models

Set new standards in terms of digestion speed, flexible use and result reproducibility with the IR SpeedDigester. Achieve an increased sample throughput for nitrogen determination by Kjeldahl digestion and multiply instrument functionality whenever needs are changing.

High Speed and Throughput

  • Fast heat transfer of infrared heaters to samples
  • Large time savings due to fast heating and cooling
  • Increased sample throughput due to shortened process time
  • Accelerated digestion step with continuous addition of H2O2

Flexible

  • One instrument for both Kjeldahl and reflux digestion
  • All BUCHI sample tubes to be used (100 mL, 300 mL, 500 mL)
  • Sample tubes compliant with ISO 6060 for COD or other reflux digestion (e.g. aqua regia)
  • Dedicated suction module for aqueous samples

Safe

  • Sealed suction module for effective transfer of harmful fumes
  • Effective neutralization of fumes by the Scrubber K-415
  • Safe operation and extended lifetime of fume hood

The SpeedDigester K-439 revolutionizes IR digestion. It combines the benefits of IR and block digestion in one unit. Fast nitrogen determination by Kjeldahl digestion at controlled temperatures enables an increased sample throughput. Multiply the instrument functionality whenever needs are changing.

High Speed and Throughput

  • Optional dedicated suction module for aqueous samples

Excellent Reproducibility

  • Accurate temperature control following the programmed profile
  • Storage of up to 50 different method profiles (time / temperature)
  • Digestion process shown graphically
  • Thermal homogeneity due to the innovative insulation plate

The Kjeldahl method KjelDigester reduces the block digestion process by up to two hours and meets the highest safety requirements. The high degree of automation is the perfect match to the KjelMaster System allowing for unprecedented sample throughput.

Highly Efficient

  • Acceleration of the heating and cooling step, saving up to two hours
