  Products > SPE > VertiPak™ C2

•  VertiPak™ C2 SPE is weakly non-polar, hydrophobic sorbent,
    manufactured using a trifunctional silane and endcapped
    to reduce the polar secondary interactions associated with
    surface silanol groups.
•  Slightly more polar than C18 or C8 due to short chain
    length of C2 provides less retentive than C8 and reduce
    the volume of elution solvent, a more concentrated and
    cleaner extract can be achived.
•  Typical applications include compounds which are too
    strongly retained on C18 or C8 e.g. drugs from plasma or
    serum.
•  Tube format is available in 7 tube sizes.
•  Cartridge format is available in 300mg and 600mg size.
•  Tubes or cartridges are packaged in zip sealing bag
    protective from moisture and light.
•  Includes a Performance report including the QC results,
    lot chromatogram and lot recovery test.
