A medical device having a housing () with a bore () and a lancet () slidably fitting in the bore. The lancet operates as a positive displacement piston. In a retracted position, in which the lancet is rearwardly displaced along the bore to define a fluid-containing space in the bore forwardly on the lancet tip, the fluid-containing space has a cross-section dimension to allow fluid to be retained therein by surface tension. The device has a seal () operable substantially to prevent flow of fluid from the fluid-containing space past the seal means on movement of the lancet. Displacement of the lancet between the puncture and retracted positions provides suction for drawing fluid into and along the fluid-containing space from the forward end of the bore, and/or pressure for expelling fluid from the fluid-containing space via the forward end of the bore. Also disclosed are methods for operating the device.

Method and apparatus for sampling and analysis of fluids

A cap ( ) for a chemical storage or reaction vessel comprising a seat for attachment, in use, to an opening of the vessel. A membrane ( ) formed from a resilient material and having a slit ( ) formed therein allows a substance sampling or delivery apparatus to pass therethrough in use, the membrane being positioned to slide within the seat substantially in the direction of passage of the sampling or delivery apparatus.
