QCLab Tapping Sieve Shakers deliver fast, reliable, and highly repeatable particle separation across a wide range of sizes and material types—thanks to a scientifically developed sieving action. Engineered for performance, the action combines perfect circular rotation of the sieve stack with vertical two-way tapping at a consistent 48 taps per minute. These high-capacity units can accommodate up to twenty sieves, depending on the model and sieve frame dimensions.
The precisely controlled circular motion ensures there are no “dead spots” on the sieve surface—every particle moves actively across the mesh. As particles roll in all directions, the upward tapping motion reorients and redistributes them, exposing new faces to the mesh. Meanwhile, downward taps help near-size particles pass through the openings efficiently.
Built for durability, QCLab shakers feature rugged, powder-coated steel housing and are powered by a robust 1/3 hp heavy-duty motor. Each model comes standard with QCLab’s signature EZ-Clamp system, an internal counterbalance, adjustable leveling footpads for stable setup, and a bright digital controller for precise operation.
The intuitive digital controller boasts a large, easy-to-read 0.5in (12.7mm) LED display. It allows for exact time control—up to 99 minutes and 59 seconds, with ±1 second accuracy. User-friendly features include memory recall of previous settings, a pause/resume function that maintains timing, and an end-of-cycle alert for convenience.
QCLab’s innovative EZ-Clamp system includes a built-in sieve cover that slides easily up and down the clamp rods with a simple button press. Locking the cover is just as easy: once positioned, release the button and give it a quick twist to secure it in place. After testing, you can remove the sieve stack effortlessly without adjusting the clamps, making setup for the next run quicker and easier.
