Fison TCLP Rotary Agitator holds PE extraction bottles of 2 L volume and turns them through 360-degree overturn rotation at 30±1 r/min. End-over-end rotation mixes the sample with the extraction fluid inside each bottle, and the fixed rotation speed keeps agitation uniform across all bottles. As TCLP rotary agitator equipment, the extractor keeps bottled samples in uniform overturn agitation throughout the leaching run.
