The Vac-Man® Laboratory Vacuum Manifold, when used in conjunction with the PureYield™ or Wizard® DNA Purification Systems or SV Total RNA Isolation Systems, is the ideal system for rapid, effective nucleic acid purification. Reliable, sturdy and easy to use, the Vac-Man® Laboratory Vacuum Manifold will process from 1 to 20 samples simultaneously. Because each manifold comes complete with a set of 20 individually controlled One-Way Luer-Lok® Stopcocks, as many or as few samples as desired can be processed at one time. The One-Way Luer-Lok® Stopcocks are designed to accommodate the PureYield™ Binding Columns and Wizard® Minicolumns or Maxi/Megacolumns.
