Dosing device for dispensing small amounts of liquid |
摘要 |
A dosing unit (1) for delivery of small quantities of fluid comprises a bulb (2), the interior of which is connected to a capillary (3). The other, free end of the capillary communicates with ambient air and the bulb interior has an opening (4) to the atmosphere. The opening is sized such that its flow resistance causes expulsion of a liquid contained in the capillary, when the bulb is squeezed. |
