Retsch SR 300 Rotor Beater Mill for Coarse and Fine Size Reduction
Product Description
The Retsch SR 300 Rotor Beater Mill is designed for precise coarse and fine size reduction of dry, soft, medium-hard, organic, and inorganic materials, widely used in molecular diagnostics, bioprocessing, and biotechnology research. This mill features:
- Adjustable speed settings enabling optimized milling for diverse sample types and applications
- Defined final fineness controlled by bottom sieves with aperture sizes ranging from 0.08 to 10 mm, essential for sample standardization in synthetic biology workflows
- Wide range of accessories, including various feeding systems, rotors, and sieves to customize processing needs
- Optional grinding inserts at 180° for enhanced impact milling of hard-brittle materials, critical in biomanufacturing and biochemical analysis
- Gravity outlet with 5 L or 30 L collecting vessels for batchwise collection of larger sample quantities, important in laboratory bioprocess scale-ups
- Removable hopper and exchangeable push-fit grinding insert, rotor, and cassette for simplified cleaning and maintenance
- Cyclone unit option to improve sample discharge and protect heat-sensitive samples during milling, supporting live-cell imaging sample preparation
- All contact parts (grinding chamber, feed hopper, material inlet and outlet) are made of stainless steel ensuring durability and contamination-free processing
- Electric engine brake for efficient operation safety
This rotor beater mill is vital for laboratories requiring reliable size reduction equipment in biomedical engineering, synthetic biology, and biopharmaceutical production pipelines, enabling high-quality sample preparation for downstream applications such as gene editing and molecular cloning.
