Rotating sample divider for large bulk materials
Achieve precise, dust-free division and volume reduction of bulk materials effortlessly, ensuring representative samples for reproducible analysis in your lab or production environment.

Divides and Reduces Bulk Material Samples
The Rotating Sample Divider PT 300 from Retsch GmbH revolutionizes sample management with its precision-engineered design, ensuring representative, dust-free division of large powder or granular batches. Its modular construction supports both batch-processing and continuous sampling, ideal for industries ranging from agriculture to pharmaceuticals. Operating at variable speeds between 18 and 53 rpm, it extracts multiple samples with ease or performs single-sample continuous processing with reject. Designed with a vibratory feeder and a digital interface, it ensures accurate, adaptable operation. The PT 300 can handle up to 60 liters of material and is built with a hopper that facilitates easy flow control and cleaning. It’s recognized for its strict adherence to international sampling standards, and its construction offers optional materials for enhanced resistance to aggressive or corrosive materials. The removable base frame allows operation height adjustments, making the PT 300 versatile and integrable with existing lab infrastructure.
