TopTip (Micropipette Tip Column) is a mini chromatographic column without frit or filter at the bottom and can be used with a micropipette or as a spin column in a centrifuge. This is a unique concept in solid phase extraction (SPE). Top Tip is a pipette tip with a fine slit at the bottom (slit width: 1-2 µm which permits liquid to pass through but retains the chromatographic material (20-30 µm) in the tip. This also eliminates the need for a filter and, thus, dead volume. Top Tip contains just your desired chromatography material and nothing else and is excellent for working with small samples.
- Faster sample preparation with minimal sample loss
- No contamination from the filter material matrix
- Sample volumes as small as a few microliter
- Available in different forms and volumes
