<p>A sample metering device for a liquid sample comprises at least one capillary passage (1) with a first inlet (20) for receiving sample, and an outlet (5, 5′, 7, 7′); a side passage (3,3′) extending from the capillary passage part way along the length thereof and leading to the outlet (5, 5′, 7, 7′); and a second inlet (32) located between the first inlet (3,3′) and intersection with the side passage. A fluid application region (18) for receiving a liquid sample to be tested is provided for entry to the capillary passage (1) via the first inlet (20), and a second fluid application region (29) is provided for entry of fluid such as chase buffer to the capillary passage (1). The second inlet (32) prevents any excess sample in the well (18) entering the capillary passage (1) when chase buffer is applied.</p> |
