The Vortex consists of an integrated autosampling device and multi-stirrer that is designed to increase efficiency, enhance precision and promote operator safety. The temperature controlled, heated multi-stirrer assembly feature a stainless steel tray, capable of handling both 20 ml and 40 ml vials. Each vial position has its own magnetic stirring mechanism, delivering consistent and reproducible stirring action from vial-to-vial and eliminating variability due to the dissolution process.
