High-performance digestion systems for precise protein, nitrogen, and phosphorus analysis
The Behr K-Series Kjeldahl Block Digestion Systems — models K 8, K 12, and K 20 — are designed for accurate and efficient sample digestion in chemical, environmental, and food laboratories.
Built from acid-resistant stainless steel with advanced temperature control and easy programming, these systems support up to 20 samples simultaneously using standard 250 mL digestion vessels, ensuring consistent performance and high reproducibility for Kjeldahl-based analyses.
Ideal for food, feed, environmental, agricultural, cosmetic, and pharmaceutical laboratories, the K-Series delivers reliable digestion performance for total nitrogen, protein, and phosphorus determination.
Key Features
1. Durable Stainless-Steel Construction
- Block housing, rack, and hood are made from acid-resistant, non-corrosive stainless steel for superior longevity.
- Designed to withstand harsh digestion conditions using sulfuric acid and catalysts.
2. Flexible Sample Capacity
-
Available in three models:
- K 8 – 8 sample positions
- K 12 – 12 sample positions
- K 20 – 20 sample positions
- Compatible with standard 250 mL Kjeldahl digestion vessels (behrotest® and other brands).
3. Advanced Heating and Temperature Control
- High-performance heating block ensures rapid, even temperature distribution up to 430°C.
- Behr one-button programming for quick and intuitive setup.
- Up to 25 freely configurable programs for temperature and digestion time.
- USB interface for data management and method storage.
4. Convenient and Safe Operation
- Extraction hood with exhaust collector removes fumes and acids for safe operation.
- Removable viewing door allows visual monitoring of the digestion process.
- Menu navigation in multiple languages simplifies user interaction.
5. Efficient Workflow Integration
- Works seamlessly with behrotest® standard digestion and distillation vessels.
- Compatible with most other manufacturers’ Kjeldahl units due to standard vessel dimensions.
- Compact and stable design for bench-top or rack-mounted configurations.
