Rotary cone sample divider for precise subsample division
Achieve unmatched precision in sample division with minimal waste, ensuring uniformity and reliability of subsamples for accurate downstream analysis and quality control.

Precisely Divides and Distributes Diverse Sample Materials
The Rotary Cone Sample Divider LABORETTE 27 from FRITSCH is designed for laboratories and research facilities requiring precise sample division. It operates with a centric sample feeding mechanism, directing materials onto a rotating cone that divides them into up to 30 channels, ensuring consistent chemical and physical properties in each subsample with 99.9% accuracy. This device is ideal for applications in pharmaceutical, chemical, and cement industry materials, producing fine pharmaceutical granules, vitamin supplements, and industrial additives.
Featuring a compact design and maintenance-free drive motor, the LABORETTE 27 supports continuous operation at up to 3,000 division steps per minute. It can handle both dry samples and suspensions without instrument modification. The unit allows integration with the Vibratory Feeder LABORETTE 24 and diverse vibrating equipment, enhancing its versatility in sample preparation workflows. Optional dividing heads made of stable materials like anodized aluminum and PTFE-coated aluminum ensure suitability for abrasive or aggressive samples.
Cleaning is simplified through a removable dividing head, and various funnel sizes are available to match different particle sizes. The durable cast aluminum construction and recyclable materials ensure longevity and environmental consideration. The LABORETTE 27 is an essential tool for laboratories aiming to obtain reliable analytical results through precise and representative sample division.
