  Products > SPE > VertiPak™ C18-HL

  VertiPak™ C18-HL SPE is non-polar, hydrophobic sorbent,
     manufactured using a trifunctional silane and endcapped
     to reduce the polar secondary interactions associated with
     surface silanol groups.
  High carbon loading of 23% offers stronger retention.
  Typical applications includes nonpolar compounds
     antibiotics, drugs, fatty acid, pesticides, vitamins and etc.
  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.
