The Laboratory Sample Dividers category brings together products designed to convert incoming materials into a representative and method-compatible form before measurement, extraction or analysis. In a working laboratory, the category supports more than a single task because it connects preparation, handling, operation and routine maintenance around the same method.
Poor grinding, mixing, pressing, cutting or subsampling can introduce more variability than the analytical instrument itself. For dependable results, compare sample material, required particle size or geometry, batch size, and contamination tolerance and confirm that the selected item is suitable for both the immediate task and the surrounding workflow.
The preparation route should control particle size, homogeneity, contamination, heat generation and final sample geometry. This coordinated approach is particularly useful in materials, mining, food, pharmaceutical, environmental, chemical and research laboratories, where repeatability and clear operating procedures matter. As part of the Sample Preparation Equipment range, these products can be selected with the equipment and consumables used before and after this stage.
Our Laboratory Sample Dividers range
Our collection covers benefits of a rotary sample divider, operating principle of riffle box ensure a representative sample, rotary dividers for large volumes, and choosing the correct riffle box size, giving laboratories practical choices for routine work and more specialised applications.
Benefits of a rotary sample divider
Rotary dividers like the Powteq RSD200 offer higher accuracy and automation compared to manual splitting, as they use a rotating head and constant vibration to achieve highly representative sub-samples. The most suitable format depends on sample material, required particle size or geometry, and batch size. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. In practice, this supports efforts to produce representative samples that are compatible with the chosen analytical method. It also gives staff a clearer and more repeatable procedure when multiple users or shifts share the same equipment.
Operating principle of riffle box ensure a representative sample
A riffle box, like the Retsch RT series, uses a series of alternating passages to divide the material into two equal sub-samples, ensuring that the distribution of particles remains consistent between them. When comparing options, consider required particle size or geometry, batch size, and contamination tolerance. The correct choice should fit the sample, expected workload and any equipment already used in the method. In practice, this supports efforts to produce representative samples that are compatible with the chosen analytical method. It also gives staff a clearer and more repeatable procedure when multiple users or shifts share the same equipment.
Rotary dividers for large volumes
Systems like the Powteq RSD200 are designed for higher throughputs and often include vibratory feeders to manage larger bulk material charges effectively. The most suitable format depends on batch size, contamination tolerance, and heat sensitivity. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. Used correctly, this part of the range helps laboratories produce representative samples that are compatible with the chosen analytical method. The result is a setup that is easier to train, document and maintain.
Choosing the correct riffle box size
The choice depends on the maximum grain size of your material; generally, the riffle width (e.g., 12.5 mm or 25 mm) should be approximately 2.5 to 3 times larger than the maximum particle size. When comparing options, consider contamination tolerance, heat sensitivity, and cleaning and changeover. The correct choice should fit the sample, expected workload and any equipment already used in the method. In practice, this supports efforts to produce representative samples that are compatible with the chosen analytical method. It also gives staff a clearer and more repeatable procedure when multiple users or shifts share the same equipment.

Frequently Asked Questions
What is the advantage of a rotary sample divider?
Rotary dividers like the Powteq RSD200 offer higher accuracy and automation compared to manual splitting, as they use a rotating head and constant vibration to achieve highly representative sub-samples. For sample dividers, also check contamination tolerance, heat sensitivity, and cleaning and changeover so the product fits the complete procedure.
How does a riffle box ensure a representative sample?
A riffle box, like the Retsch RT series, uses a series of alternating passages to divide the material into two equal sub-samples, ensuring that the distribution of particles remains consistent between them. Laboratories should compare contamination tolerance, heat sensitivity, and cleaning and changeover and document the selected setup for consistent use.
Can rotary dividers be used for large volumes?
Systems like the Powteq RSD200 are designed for higher throughputs and often include vibratory feeders to manage larger bulk material charges effectively. For sample dividers, also check contamination tolerance, heat sensitivity, and cleaning and changeover so the product fits the complete procedure.
How do I choose the correct riffle box size?

For sample dividers, also check contamination tolerance, heat sensitivity, and cleaning and changeover so the product fits the complete procedure.
How do I choose the right sample dividers for my laboratory?
Review contamination tolerance, heat sensitivity, cleaning and changeover, and sample material, together with expected workload and cleaning or maintenance requirements. A suitable product should fit the full method, not only the immediate task. Laboratories should compare contamination tolerance, heat sensitivity, and cleaning and changeover and document the selected setup for consistent use.
