Abstract
The present invention relates to devices and methods for collecting liquid samples such as for removing a target liquid sample fraction from a larger liquid sample, e.g., from a biological sample. These devices and methods are particularly useful for rapidly and cost-effectively removing the buffy coat layer from an anticoagulated blood sample. These devices and methods have the advantage that the removal can be made on blood sample processed by ordinary centrifugation and do not require more complicated or costly processing techniques such as density gradient centrifugation.
Claims22
A fluid sample collection device, comprising:
- a cylindrical solid comprising first and second ends opposed on a length axis of the cylindrical solid, and a plurality of bores substantially parallel to the length axis of the cylindrical solid and continuous from the first end through the second end,
- wherein the first end is configured to directly couple to a means for applying a vacuum, wherein each bore of the plurality of bores defines a circular cross-section, and wherein the plurality of bores are arranged in an array which has a hexagonal, a partial hexagonal, an approximately hexagonal, a heptagonal, or a trigonal packing pattern.
A fluid sample collection device, comprising:
- a cylindrical solid comprising first and second ends opposed on a length axis of the cylindrical solid, and a plurality of bores substantially parallel to the length axis of the cylindrical solid and continuous from the first end through the second end,
- wherein the first end is configured to directly couple to a means for applying a vacuum, wherein the cylindrical solid comprises markings or etchings to indicate a volume of a liquid sample contained within the device.
