Abstract (en)
[origin: EP0250243A2] The invention provides a burette having a body 1 adapted to receive at one end a releasable reagent container 3 having a removable end fitting with a cannula 7 such that the cannula 7 ruptures a self-re-sealing diaphragm of the reagent container 3 when the end fitting is mounted on the reagent container 3, and that the diaphragm is allowed to re-seal when the end fitting is removed. The burette also includes an electric linear actuator comprising a stepping motor 8 and a reciprocable drive shaft 9, and includes a re-chargeable battery 10 with power to the stepping motor 8 controlled by a push button 11. A further push button 12 re-sets a digital display means 13. An interface socket 14 allows the burette to be connected to an external controller such as a microcomputer, and may serve as a power input connector for battery charging.
