Key Features

Infrared Digestion (InKjel 1225 P):

• Rapid direct infrared heating; quartz heaters reach 830°C in 1 minute.
• Multi-level console with fume extraction unit and glass digestion vessels.
• Supports 250 ml, 500 ml, and 750 ml vessels; larger vessels suitable for water analysis.
• Quick adaptation for different vessel sizes via exchangeable racks and fume extraction units.
• 25 freely configurable programs for block temperature and digestion time.
• One-button operation with menu navigation in the local language.
• Windows software allows bidirectional transfer of application-specific time/temperature profiles via RS232 interface.
• Standard application library included on CD for fast setup.
• Enables problem-free digestion of difficult samples with precision control.

Efficient Extraction System (behrosog 3):

• Environmentally friendly design; no connection to water supply needed.
• Infinite regulation of airflow: 16–40 L/min.
• Easy exchange of liquids via simple emptying of glass vessels.
• PTFE-coated double-head membrane pump with integrated droplet separator.
• Gas wash bottles (2000 ml each) for cooling hot gases and neutralization.
• On/off switch outside hazard zone, transparent safety door, removable drip tray.

Steam Distillation Unit (S3):

• High-performance and safe distillation.
