The BEHR behrotest® Kjeldahl Block Digestion Systems with Automatic Lift represent the next generation of safe, efficient, and automated Kjeldahl digestion.
Engineered for both 100 mL (micro) and 250 mL (standard) digestion vessels, these systems combine powerful block heating, automated sample lifting, and intelligent digital control to ensure precision, safety, and user convenience.
Available in four configurations — K 12 L, K 20 L, K 24 L, and K 40 L — the K-Block Lift series eliminates manual handling of hot sample racks and acids, enhancing both laboratory safety and efficiency.
Key Features
1. Fully Automatic Lift System
- Integrated automatic sample lift removes the need for manual handling of heavy, hot digestion racks.
- Lift mechanism raises the rack and extraction hood after digestion for cooling and safety.
- Programmable cooling and extraction time for consistent, hands-free operation.
2. Smart Control & Connectivity
- behr one-button operation for intuitive programming of temperature and time profiles.
- Windows-compatible software enables bi-directional transfer of methods and programs between the system and PC.
- Supports up to 25 freely configurable digestion programs.
- USB interface for data storage, profile transfer, and documentation.
3. Intelligent Heating & Temperature Control
- Uniform block heating up to 430°C ensures consistent digestion across all samples.
- High-performance stainless-steel heating block with precision temperature control.
- Multilingual menu navigation simplifies global laboratory use.
4. Safe & Efficient Design
- Automatic lift eliminates manual acid handling and risk of burns or splashes.
- Extraction hood with exhaust collector removes toxic fumes.
- Removable viewing door allows visual monitoring of digestion progress.
- Built-in software manages lift timing, cooling, and extraction automatically.
5. Robust Stainless-Steel Construction
- Non-corrosive, acid-resistant stainless-steel housing for long operational life.
- Sturdy frame, extraction hood, and insert rack designed for continuous use in harsh chemical environments.
