The all-layer sampler with open inner tube is ideal for taking full-depth or mixed samples from all types of bulk materials, from fine powders to large grains. It ensures representative sampling through all layers or zones, providing accurate results for analysis and quality control. Perfect for bins, silos, piles, bags, or drums, it can be used vertically or horizontally for maximum versatility. The open inner tube without separate chambers allows sampling across the entire length, delivering a large collection volume for detailed analysis. A minimal gap between inner and outer tube reduces contamination risk, while the removable tip enables thorough cleaning and prevents cross-contamination. Built with a robust design and high-quality craftsmanship, this sampler offers long-lasting durability, precision, and reliability, even with frequent industrial or laboratory use.
