ABSTRACT:
Biological sampling apparatus have a barrel defining a chamber with a narrow passageway at one end and an absorbent analytical test means in the chamber. In one embodiment, an integral frit is provided with a first portion acting as a splash filter and located in the chamber, and a second portion integral with said first portion acting as a wick. The second portion extends through the narrow passageway. A portion of the splash filter is hydrophobic, and at least a portion of the wick is treated with a wetting agent and is hydrophilic. In another embodiment, a splash filter is located in the chamber and a separate hydrophilic wick is provided having a first portion located in the narrow passageway and a second portion located outside the passageway and barrel. The second portion has a bulbous portion capable of absorbing substantially more fluid sample than the first portion.
