P-97 needle puller

In biological experiments, electrodes are usually precisely inserted into cells. The electrodes are usually drawn from glass tubes and microelectrodes
The drawing machine is a commonly used tool for pulling glass tubes into electrodes. Its basic principle is to place the glass tube in a heating wire and then control it
The temperature of the heating wire is set to achieve the goal of burning the glass tube. While heating the glass tube, a certain amount of tension is applied at both ends of the tube,
Pull the glass tube into various required electrodes for experimental purposes. P-97 programmable horizontal microelectrode produced by Sutter Corporation in the United States
Instruments are commonly used for the drawing and fabrication of various glass, quartz, and other microelectrodes. As commonly used microelectrodes for glass, quartz, and other materials in experiments
Electrophysiology and cell injection experiments are widely used, and Sutter's P-97 programmable horizontal microelectrode puller from the United States has been developed
Confirmed as standard equipment for electrophysiological and cell injection laboratory.
