Tip Collar with Integrated Filters

Abstract

A disposable filter tip collar provides an improved system for using filters in conjunction with disposable pipette tips. The filters are installed into the tip-holding collar rather than inside each tip as in current use. The separation of the filters from the tips in this manner offers significant advantages for ease of use, cost, and pipetting performance. Because the filters are separate from the tips, the available liquid pipetting volume within the tips is not diminished as it is using the current system, which allows for more consistent pipetting and method development between filter and non-filter tips. Since the filters are not limited in size by the internal diameter of the pipette tips, larger diameter filters can be used which are more efficient and allow better pipetting performance.
