  Products > SPE > VertiPak™ DIOL

 VertiPak™ Diol SPE is polar sorbent that can exhibit both  
    polar and non-polar interactions, depending on the
    preparation of the column and the nature of the sample
    matrix.
 As polar interaction, Diol is more reproducible than Silica.
    As non-polar interaction, Diol can extract relatively nonpolar     molecules from aqueous samples.
 Typical applications include anitibiotics, prostagladins, THC
    in urine.
 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.
