| Abstract: | This paper presents a novel horizontal microelectrode puller based on Bluetooth technology,discusses the mechanical structure and hardware circuit for the micropipette puller,and the control software was developed by using LabVIEW platform.The software interface was dedicated to set the microelectrode parameters and indicate the pulling progress on PC.The BlueCore4 Bluetooth module transmitted the setting parameters to a microcontroller in the puller.The experiment results showed that the microelectrodes produced by the instrument were featured with good tip profile and low serial impedance for patch clamp experimental requirements.This puller is easy to operate and set pulling parameter,produce two symmetrical electrodes in each one progress.It’s a good tool for electrophysiology experiments. |
