Specifications & Key Features
High-speed drive: Delivers the rotational energy needed for rapid laboratory blending, dissolving and dispersion.
Variable-speed control: Enables gradual acceleration and process adjustment for different materials and batch stages.
Manual Lifting: Supports convenient shaft positioning, vessel loading and removal, blade inspection and cleaning.
Stainless-steel product-contact parts: SS 304, SS 316 or SS 316L options can be considered according to compatibility and hygiene requirements.
Stable column and base: Help maintain shaft alignment and smooth operation during high-speed processing..
Compact laboratory footprint: Fits efficiently into formulation, testing, development and quality-control areas.
Accessible wetted parts: Simplify cleaning, inspection and product changeover.
Faster laboratory processing: Vigorous circulation can reduce the time required for routine blending and dissolving tasks.
Uniform product quality: Continuous circulation supports even distribution of liquids, additives, pigments and suspended ingredients.
Controlled mixing intensity: Variable speed helps the operator balance circulation, shear, aeration and temperature rise.
Repeatable trials: Defined blade, speed, time and batch conditions make laboratory results easier to reproduce.
Flexible formulation work: One machine can support blending, dissolving, premixing, suspension and selected dispersion duties.
Better scale-up understanding: Controlled high-speed trials help identify useful process parameters before pilot or production testing.
