Buchi K-425 Basic Unit 110-120V 1154251000

The SpeedDigester K-425 Basic Unit is an infrared (IR) digestion instrument for laboratory mineralization and reflux digestion workflows. It performs Kjeldahl and reflux digestions (including COD and aqua regia applications) using interchangeable BUCHI sample tubes and provides individual control of its two heating chambers for homogeneous heating and reduced foaming. The unit operates at 110-120V and is identified by manufacturer part code 1154251000.

Key Features:

• Model: K-425 Basic Unit (manufacturer part code 1154251000)
• Operating voltage: 110–120 V
• Maximum temperature: 580 °C
• Sample positions: 5–12 (compatible with BUCHI sample tubes: 100 mL, 300 mL, 500 mL)
• Two individually controllable infrared heating chambers

Advantages:

• Flexible: combines Kjeldahl and reflux digestion in one instrument and accepts multiple BUCHI sample tube sizes.
• High speed and throughput: faster heat transfer from IR heaters and quicker cool-down reduce processing times.
• Improved sample handling: individually controlled heating chambers and optimized warming minimize foaming and ensure homogeneous heating.
• Safety and convenience: compatible with closed suction modules and BUCHI Scrubber K-415 for efficient removal and neutralization of hazardous vapors.
