General description

The VM20 Vacuum Manifold is designed to provide increased efficiency and performance when used with many of Sigma′s column-based nucleic acid purification systems. The manifold is capable of processing 20 samples simultaneously and includes a stepped design for easy access to every column. Dual vacuum connection ports allow for multiple configurations for waste collection. Waste can be collected in the manifold body or, through use of a threaded drain port, diverted to any auxiliary reservoir providing virtually unlimited capacity. The manifold includes chemically resistant Endura-Luer stopcocks that will not crack or break with repeated use.


VM20 Vacuum Manifold has been used for the isolation of circulating tumor cells by filtration with track-etched membranes.

Features and Benefits

  • Capable of processing 20 samples simultaneously
  • The dual port design allows waste to be collected in the manifold body or diverted to any auxiliary reservoir
  • Stepped design for easy access to every column
  • Endura-Luer stopcocks instead of plugs
  • Chemically resistant polypropylene


Kit contains the Sigma VM20 Vacuum manifold, 20 Endura-Luer stopcocks, and VM20 Accessory Pack with cap and 2 nozzles.

Physical properties

This product is made out of chemically resistant polypropylene.
We have created Endura-Luers to be an enhanced stopcock that
resists chemical erosion, cracking, and breaking.
