Buchi K-439 12x300ml 1154392100

Entry-level infrared SpeedDigester designed for rapid sample digestion and higher sample throughput. The K-439 performs Kjeldahl and reflux digestion for applications such as Total Kjeldahl Nitrogen (TKN), Chemical Oxygen Demand (COD), heavy metals and phosphate analyses, using twelve sample positions with 300 mL sample tubes. The instrument offers fast heating and quicker cool-down to reduce processing time and supports continuous H2O2 addition for accelerated digestion.

Key Features:

• Model: K-439 (part number 1154392100)
• Sample positions: 12
• Sample tube volume: 300 mL
• Maximum temperature: 580 °C
• Supported applications: TKN, COD, heavy metals, phosphate
• Compatible sample tube sizes: 100 mL, 300 mL, 500 mL (uses 300 mL configuration)

Advantages:

• Higher sample throughput through faster infrared heating and reduced cooling times.
• Flexible operation allowing both Kjeldahl and reflux digestion methods in a single instrument.
• Accelerated digestion with continuous addition of hydrogen peroxide.
• Enhanced safety via sealed suction modules for efficient removal of harmful fumes.
