Buchi K-436 10x500ml 1154362500

The SpeedDigester K-436 is an infrared (IR) laboratory digester designed for rapid chemical digestion of samples for analyses such as Kjeldahl nitrogen determination and chemical oxygen demand (COD). The instrument provides fast heating and accelerated cool-down to increase sample throughput and supports both Kjeldahl and reflux digestion workflows. It is intended for laboratory use where controlled, high-temperature digestions are required.

Key Features:

• Model: K-436
• Sample capacity: 10 positions using 500 mL sample tubes (10 × 500 mL)
• Max. temperature: 580 °C
• Compatible with BUCHI sample tubes of 100 mL, 300 mL and 500 mL (ISO 6060 compliant)
• Individual operation of each heating chamber
• Suitable applications: Total Kjeldahl Nitrogen (TKN), COD, heavy metals, phosphate; supports Kjeldahl and reflux digestion

Advantages:

• Higher sample throughput through rapid infrared heating and quicker cool-down reducing digestion times
• Flexible use for Kjeldahl and reflux digestions with support for multiple tube sizes including 500 mL
• Individual chamber control enables tailored processing per sample set, improving workflow flexibility
