TopTip (packed micro-spin column)

Micro-spin column packed with media

  • Significantly reduce time and expense of SPE (e.g., can top-load samples and centrifuge)
  • Accomodates wide spectrum of volumes and allows precise control over rates of binding and elution
  • No filters, glues, polymers, or matrices: reducing sample loss and contamination risk

TopTip enables high-fidelity chromatographic separation of even ultra-low concentration samples.
The fine 1-2 µm slit at the bottom of the TopTip permits liquid to pass through (with pressure via centrifuge or syringe), but retains chromatographicmedia in the tip. This eliminates the need for a filter – reducing dead volume, loss of sample and contamination risk.

TopTip technology has powered research resulting in many publications: Explore literature featuring TopTip.
