摘要： An apparatus for dispensing droplets comprises a dispensing tip (2, 190, 210) with an orifice (4) having a cross sectional area in the range of 0.00002 mm2 to 0.03 mm2. An actuator assembly (13-15, 50, 80) comprising an actuator element engages with and disengage from the tip and, when engaged, couples acoustic energy to liquid in the tip to expel the liquid through the orifice as a droplet. The actuator assembly includes one or more piezo elements, which may be in the form of piezo stacks. In some embodiments, the actuator assembly comprises a plurality of jaws (51, 52, 61) adapted to move to engage with the dispensing tip for dispensing. This allows side loading of the tip (180) followed by movement of the actuator assembly (153) to engage the tip (180).

摘要： A temperature sensor (1) has a pressure sensor (10), the distal end of which is inserted in a sealed chamber (2) filled with a liquid. The pressure sensor has a light guide (4), a cavity (14) at a distal end of the light guide, a diaphragm (11) forming a wall of the cavity and being configured to deflect with applied pressure, and a detector to detect changes in light reflection due to deflection of the diaphragm. The liquid (3) which changes volume in response to temperature changes and this volume change is sufficient to change the pressure applied on the diaphragm (11), and the a interrogation system processes pressure data and/or light reflection data to generate an output indicating temperature of the fluid in the chamber.
