Abstract
A capillary transfer pipette includes a draw tube having a distal end defining a draw tube opening through which liquid is drawn via capillary action, a proximal end, and a lumen. A squeeze bulb is arranged proximally of the draw tube and defines a fluid chamber in fluid communication with the lumen, the squeeze bulb being compressible to dispense drawn liquid from the draw tube. An air vent hole is formed in at least one of the draw tube or the squeeze bulb, and is configured to vent air to facilitate drawing of liquid through the draw tube opening via capillary action. A volume indicating element may be provided on the draw tube, and the air vent hole may be located proximally of the volume indicating element. The lumen may be formed with a first diameter at the proximal end and a differing second diameter at the distal end. Methods of collecting liquid with, and of making, a capillary transfer pipette are also disclosed.
