The BEHR behrotest® SIST 100 Boiling Stones are premium-quality anti-bumping granules designed to ensure smooth, uniform boiling during Kjeldahl digestion and steam distillation.
By preventing sudden boiling and sample splashing, SIST 100 improves digestion safety, enhances sample recovery, and supports accurate analytical results in nitrogen and protein determinations.
Specially formulated for use with BEHR behrotest® digestion and distillation systems, these inert granules maintain stable thermal transfer and boiling behavior even in the presence of concentrated acids and catalysts.
Key Features
1. Anti-Bumping Function
- Effectively prevents sudden boiling, bumping, and frothing during sample digestion.
- Ensures uniform heat distribution for consistent analytical outcomes.
- Minimizes the risk of sample loss or spillage during vigorous boiling stages.
2. Chemically Inert Composition
- Manufactured from acid-resistant and heat-stable materials suitable for Kjeldahl applications.
- Remains chemically inert in concentrated H₂SO₄ and catalyst mixtures.
- Provides reliable performance throughout long digestion cycles.
3. Optimized for Kjeldahl Systems
- Designed for use in BEHR behrotest® K-Series digestion blocks and steam distillation units.
- Compatible with all standard Kjeldahl glass vessels (100–750 mL).
- Suitable for both micro- and macro-Kjeldahl digestion procedures.
4. Easy and Safe to Use
- Supplied as ready-to-use boiling granules—simply add to the digestion vessel before heating.
- Non-toxic, non-reactive, and safe for laboratory handling.
- Ensures consistent sample heating and faster digestion times.
5. Economical Packaging
- Supplied in a 100 g tin for long-term laboratory use.
- Lightweight, easy to dispense, and ideal for high-throughput analytical operations.
