General description

SPE is a form of chromatography, and, as with other chromatographic techniques, control of flow rate is critical for maintaining reproducible extractions. Unlike other vacuum manifolds, the Visiprep system contains a patented valve system that allows for precise flow control through each SPE tube via rotating, independent, screw-type valves situated in each port within the manifold cover. Visiprep vacuum manifolds allow you to process up to 12 (12-port version) or 24 (24-port version) SPE samples simultaneously. Spacing between ports are slightly smaller on the 24-port versions than the 12-port versions so consideration of tube sizes is recommended.

Application

Visiprep™ SPE Vacuum Manifold was used to perform solid phase extraction, to separate polyphenols from grapes, in order to determine the polyphenol content using LC-MS analysis. It was also used for concentration and purification of solvent extracts from surface water and sewage water sediments. Furthermore it was used to extract and determine, estrone in water using solid-phase extraction-enzyme-linked immunosorbent assay (SPE-ELISA).

Features and Benefits

  • Patented screw-type valves within each SPE port for precise flow control
  • Glass basin will not dissolve, fog, or discolor when exposed to solvents
  • Legs on cover allow user to easily rest cover on work surface when removed from the manifold
  • Screw-type solvent-resistant vacuum bleed gauge and valve offer better sealing and vacuum control. Valve takes 1/4″ vacuum tubing.
  • PP collection vessel rack accommodates autosampler vials; small scintillation vials (22.75 mm O.D. recommended); 10 and 16 mm test tubes; and 1, 2, 5, and 10 mL volumetric flasks. An optional plate for 20 mL scintillation vials is available for 12-port models.

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. When I purchase the Visiprep SPE Vacuum Manifold, Product 57030-U, what additional components are required to begin using it immediately?

    The Visiprep SPE Vacuum Manifold (57030-U) includes most items which would be required for immediate operation. Additional required items are the SPE tubes themselves, a vacuum source, and tubing to connect the manifold to the vacuum source.

  4. Do you have a recommendation for the tubing required to connect Visiprep™ SPE Vacuum Manifold (57030-U) to my vacuum source?

    Although any 1/4" ID flexible tubing should be suitable for this purpose, the product number Z255998-1PAK (10ft length) would be appropriate for this application.

  5. What is the maximum vacuum that the Visiprep Vacuum Manifold, Product 57030-U, can handle?

    The maximum vacuum that the Visiprep Vacuum Manifold can handle is 20 inches of Mercury (Hg).
