The Vortex autosampler consists of an integrated autosampling device and multi-stirrer and is designed to increase efficiency, enhance precision, and promote operator safety. The temperature controlled, heated (up to 150°C) multi-stirrer assembly features a stainless steel tray capable of handling both 20 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. When coupled with the company's Triple Detector Array or Relative Viscometer, it provides a complete automated system for macromolecular characterization and determination of solution viscosities.
