The BEHR behrotest® Catalyst Tablets (KT Series) are high-performance digestion aids formulated to accelerate Kjeldahl nitrogen and protein analysis.
Each tablet is precisely composed of selected catalysts and promoters—such as potassium sulfate (K₂SO₄), copper sulfate (CuSO₄), titanium dioxide (TiO₂), and selenium (Se)—to ensure uniform heat transfer, consistent oxidation, and complete sample digestion.
Available in multiple formulations and package sizes, these tablets are optimized for use in BEHR behrotest® digestion systems as well as most standard Kjeldahl apparatus, supporting fast, reproducible analytical results across food, feed, agricultural, and environmental laboratories.
Key Features
1. Optimized Catalyst Composition
- Uniform tablet weight ensures reproducible digestion results.
- Formulated with high-purity catalytic agents for efficient sulfuric acid oxidation.
- Enhances boiling and oxidation rates, minimizing digestion time.
2. Compatible and Easy to Use
- Directly compatible with BEHR behrotest® K-Series digestion systems (K 8, K 12, K 20) and other standard Kjeldahl devices.
- Supplied in pre-weighed tablet form, eliminating weighing errors and handling of hazardous powders.
- Ready to use—simply add one tablet per digestion vessel.
3. Stable and Long-Lasting
- Hermetically sealed tins ensure protection from humidity and degradation.
- Long shelf life, suitable for routine laboratory use.
- Available in tins of 500 or 1000 tablets depending on laboratory throughput.
4. Application Range
- Ideal for determining total nitrogen, protein, and ammonia in food, feed, fertilizers, wastewater, soil, and chemicals.
- Suitable for micro-, semi-, and macro-Kjeldahl methods.
