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.
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.

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.[1] It was also used for concentration and purification of solvent extracts from surface water and sewage water sediments.[2] Furthermore it was also used to extract and determine estrone in water using solid-phase extraction-enzyme-linked immunosorbent assay (SPE-ELISA).[3]

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

Questions

1–8 of 8 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. Will the racks suit collection in 50mL centrifuge tubes? My principal concern is in cross contamination between adjacent samples. Does this system prevent or reduce aspiration of fine particles during elution?

    1 answer

    1. The racks for the 24-port model of the Visiprep™ SPE Vacuum Manifold are designed for use with smaller collection vessels. The widest collection vessel recommended for the 24-port model is a small 22.75 mm outer diameter scintillation vial. Since 50 mL centrifuge tubes have a nominal outer diameter of 30 mm, they would not fit this model.

      There is no containment system to separate collection vessels during sample processing. The disposable liner from each port can be inserted with slight depth into the respective collection vessel to reduce the likelihood of fine solvent particles being aspirated into the manifold.

  3. What is the spacing between ports for the manifolds?

    1 answer

    1. Visiprep 24 Port, Product Dimensions
      7/8" (0.875") Between valves (center to center)
      1 3/8" Between rows (center to center)
      All ports on the 12 and 24 vacuum manifolds can only be used simultaneously with 1, 3, and 6mL tubes. In order to use all ports of the manifold with 12, 20, or 60 mL SPE tubes, Long Stem Flow Control Valves are required – see product 57048.

  4. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
