  Products > SPE > VertiPak™ C8

 VertiPak™ C8 SPE is moderately non-polar, hydrophobic
    sorbent, manufactured using a trifunctional silane and
    endcapped to reduce the polar secondary interactions
    associated with surface silanol groups.
 Less retentive than VertiPak™ C18 based on non-polar
    interaction.
 Typical applications include molecules of wide range of
    polarity in water or aqueous biological samples e.g.
    pesticides or PCBs in water, vitamins in 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.
