Buchi K-425 230V 6x300ml KB 1154252200

The SpeedDigester K-425 is an infrared (IR) digestion instrument for laboratory sample preparation that combines Kjeldahl and reflux digestion in a single unit. It uses IR heating to rapidly transfer heat to samples and shorten cool-down times, increasing sample throughput for applications such as Kjeldahl (total nitrogen/protein), COD, heavy metals, phosphate and aqua regia digestions. The unit configuration is 230 V and accommodates six 300 mL sample tubes in the KB 1154252200 configuration.

Key Features:

• Supply voltage: 230 V
• Sample capacity/configuration: 6 × 300 mL (KB 1154252200)
• Maximum temperature: 580 °C
• Compatible sample tube sizes: 100 mL, 300 mL, 500 mL (BUCHI sample tubes, ISO 6060 compliant)
• Sample positions per run: 5–12 (adjustable depending on configuration)

Advantages:

• Faster heat transfer and quicker cool-down via infrared heating increases sample throughput and reduces processing times.
• Combines Kjeldahl and reflux digestion workflows in one instrument for flexible multi-application use (e.g., TKN, COD, hydroxyproline, aqua regia).
• Compatibility with multiple BUCHI tube sizes and individual chamber control enables adaptable processing and homogeneous heating across samples.
• Option for closed suction modules and integration with a scrubber for efficient removal and neutralization of hazardous vapors enhances laboratory safety.
