摘要： A temperature controller (10) for the reaction chambers of a microfluidic chip or lab on a chip is disclosed' with an insulator block (11) which supports the chip (not illustrated) and metallic heat conductors (12) positioned in vias in the insulating block that coincide with the positions of the reaction chambers of the microfluidic chip. Locking means (13) hold the chip in position. A cooling/heating block (14) such as a Peltier element provides the thermal changes which spreads by conduction up to the vias to heat the reaction chambers of the chip. A heat sink (15) with eg cooling fins dissipates unwanted heat.

摘要： The present invention provides a sensor for sensing vibration. The sensor having a container for containing conductive fluid; a ground electrode provided within the container, wherein the ground electrode is in contact with the conductive fluid when the sensor is in an operational; and a sensing electrode adjacent to the ground electrode in space, the sensing electrode is configured to be in a close proximity to the conductive fluid. In operation, the conductive fluid causes electrical conduction between the ground electrode and the sensing electrode when fluid ripples occur and the sensing electrode touches the conductive fluid. The sensor further provides a fluid level detector for triggering an automatic refiller to refill fluid when the fluid level drop below a desired level.
