High speed and throughput

Save time thanks to faster heat transfer from infrared heaters to samples and a quicker cool-down process. Increase your sample throughput by reducing the processing times. Accelerate your digestion step with continuous addition of H2O2.

Flexible

The SpeedDigester K-425 / K-436 combines both Kjeldahl and reflux digestion in one instrument. Flexibly use any BUCHI sample tubes (100 mL, 300 mL, 500 mL), which are compliant with ISO 6060 for COD or other reflux digestion (e.g. aqua regia). The SpeedDigester is also suitable for aqueous samples thanks to a dedicated suction module.

Safe

Improve your safety with sealed suction modules that make efficent transfer of harmful fumes possible. Combine with Scrubber K-415 to achieve effective neutralization of fumes, operate the unit safely and extend the lifetime of your fumehood.

  • Reduce digestion time up to two hours by fast heating, cooling and the continuous addition of H2O2 through the capillary funnels.
  • Use the SpeedDigester for multiple applications like Kjeldahl, micro-Kjeldahl, COD, hydroxyproline or aqua regia digestion and choose the appropriate glass assembly.
  • Drip tray for convenient and safe storage of the suction modules. Save bench space and store the rack in the cooling position.
  • Individual operation of each heating chamber. Manual temperature setting are infinitely variable from level 1 to 10.
  • Operation is safe and lifetime of the fume hood is extended. A sealed suction system captures harmful fumes and the Scrubber K-415 neutralizes them.
