easy to use interconnects to your amplifier. Designed to facilitate recording and stimulating from tissues submerged in saline, suction is applied via the side access port in order to draw the tissue near the electrode tip. This connector is compatible with the Threaded Syringe, a sophisticated method for precisely adjusting the amount of negative pressure applied that avoids the inconsistency and large forces required with a typical pull-back plunger style syringe. it is quite easy to record extracellularly from very small hearts (insects), intestinal nerves, eye neurons and to stimulate muscles by an electrical pulse to their neurons.
