The PC-505B is the lowest noise, switchable resistive-feedback patch clamp amplifier available. This new model also has features of particular interest to those doing whole cell studies. The slow capacitance compensation circuitry has been combined into a single control and allows direct measurement of membrane capacitance. The companion Series R control displays the access resistance and the new % correction circuit compensates up to 90% of the access resistance. These and other new features make the PC-505B an extremely capable amplifier.
