Vacuum Filtration Units come in many forms, from complete units (with vacuum) all the way to specialized components which are adaptable to your own vacuum system. We offer Funnel top and inline vacuum filtration systems for users who wish to attach their vacuum tube directly to the unit. Pour fluid quickly into the funnel top, or attach tubing to the inline which will draw from your vessel. Alternately, the complete Vacuum Aspirator Collection System is a self-contained and portable collection system that requires only a pipette tip and an electrical outlet to function. Its internal vacuum allows it to be portable and easy to use.
