RIFFLE SAMPLE DIVIDER AZA0980
The AZA0980 Riffle Sample Divider is a precision laboratory instrument designed for accurate and unbiased splitting of bulk material samples into representative portions. It is widely used in geotechnical, construction, mining, and agricultural laboratories to ensure that test samples remain statistically reliable and repeatable.
Manufactured for durability and precision, this unit is ideal for reducing large quantities of soil, sand, aggregates, cement, and powdered materials to manageable, test-ready sizes.
Key Features
- Accurate material splitting for laboratory testing
- Heavy-duty corrosion-resistant metal construction
- Uniform slot widths for consistent sample division
- Smooth-flow chute design for minimal sample loss
- Supplied with two receiving pans for clean, efficient operation
- Compact bench-top design
Description
Construction & Design
The AZA0980 consists of a controlled-feed hopper mounted above precision-machined alternating chutes (riffles). These chutes direct material evenly into two separate collecting pans, creating two equal and representative sub-samples. Repeating the process ensures high statistical accuracy without operator bias.
The body is fabricated from powder-coated or galvanized steel to resist corrosion and wear, making it suitable for long-term laboratory and site use.
