YU SHUO DA vacuum aspiration system is a vacuum-controlled laboratory liquid aspiration unit built around a 4 L collection bottle and a self-closing connector head. An adjustable vacuum up to -600 mbar and 15 L/min maximum air flow let one unit handle cell culture media removal, DNA extraction waste and microplate waste removal. The operating handle rests in an integrated holder on the bottle cap, and the bottle, tubing and handle can be dismantled without tools for routine cleaning. OEM logo and graphic customization is available from one piece.
