Opis ogólny

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.
The Visiprep DL (Disposable Liner) Vacuum Manifold eliminates the possibility of cross-contamination when processing a new sample on the same port. The liner consists of a PP female luer hub that attaches to the SPE, and thin-walled PTFE tubing that is threaded through the SPE port. This ensures that all SPE port and valve surfaces coming in contact with the sample can be replaced following each extraction.

Zastosowanie

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 also used to extract and determine estrone in water using solid-phase extraction-enzyme-linked immunosorbent assay (SPE-ELISA).

Cechy i korzyści

  • 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.
Supplied with 100 disposable liners (Part No. 57059).
