Incision-based filtration/separation pipette tip
First Claim
1. A pipette tip for sample preparation, which contains chromatography particles and has an open upper end and a closed lower end and has one or more slits at said lower end to permit the passage of fluids through said slits while retaining said chromatographic particles in said pipette tip, said slits having a length to width ratio of 200:
- 1 to 400;
1, a ratio of chromatographic particle diameter to slit width ratio 4;
1–
6;
1, and a ratio of chromatographic particle diameter to slit length 1;
33.33 to 1;
100.

Abstract
This invention relates to a pipette tip designed to perform filtration or sample separation on the basis of one or more perforations, holes or incisions performed on the tip. Such perforation, holes or incisions are large enough to permit the passage of fluids or smaller particles, but small enough to block the passage of solid materials or larger particles, such as those including chromatography media. Such a pipette tip can thus be used for the filtration or separation of samples without the use of a filter, secondary solid matrix or any other components needed to hold chromatography media and other solid matrices within the pipette tip during the separation process.
