<p>An apparatus for sampling and dispensing a liquid. The apparatus comprises a liquid receiving region having a liquid receiving orifice, and a pump for controlling the gas pressure in the receiving region such that liquid can be drawn into the receiving region and dispensed from the receiving region via the orifice in the receiving region. There is also means for controlling the pump such that, when liquid is drawn into the receiving region, the gas region between the receiving region and the pump that does not contain liquid is saturated with vapour from the liquid being sampled. A corresponding method is also provided.</p> |
