Description

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.

Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
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.
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.
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).
