SpeedDigester K-425 / K-436 / K-439
The entry level IR digester
Set new standards for digestion speed, flexible use and result reproducibility with the IR SpeedDigester. Achieve higher sample throughput for nitrogen determination by Kjeldahl digestion and multiply functionality with this entry level IR digester.
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.
Select the suction module that suits your need best.
- Standard: suitable for most applications
- With condensate trap: perfect for aqueous samples
- Suction module with capillary funnels: to accelerate the digestions
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.
