Buchi K-439 12x300ml H2O2 1154392300

SpeedDigester K-439 configured for 12 sample positions with 300 mL sample tubes and continuous H2O2 addition (order number 1154392300). The instrument is an infrared (IR) digester designed to perform Kjeldahl, COD and other reflux digestions by providing rapid, homogeneous heating of samples and the option for continuous peroxide addition to accelerate digestion. Typical use cases include total Kjeldahl nitrogen (TKN), chemical oxygen demand (COD), heavy metal and phosphate digestion workflows in analytical and industrial laboratories.

Key Features:

• Sample positions: 12
• Sample tube size: 300 mL
• Maximum temperature: 580 °C (temperature range 50–580 °C)
• Continuous H2O2 addition capability to accelerate digestion
• Display and programmable temperature programs included
• Manufacturer order number / configuration: 1154392300

Advantages:

• Higher sample throughput via fast IR heating and quicker cool-down, reducing digestion times
• Accelerated peroxide digestions through continuous H2O2 addition, shortening processing time
• Flexible application: supports Kjeldahl, micro‑Kjeldahl, COD, hydroxyproline and aqua regia digestion
• Improved safety with sealed suction modules and compatibility with Scrubber K-415 for neutralization of fumes
