Model 2400 Patch Clamp Amplifier

Amplifier current gain can be matched to your experimental needs by selecting one of the three available dual resistive feedback probes, as the gain is partially determined by the value of the resistor in the headstage. There are three heastages to choose from: 1 GΩ/10 MΩ, 10 GΩ/10 MΩ, and 10 GΩ/100 MΩ. The wide range of feedback resistors means currents can be recorded with outputs of 1 mV/nA to 10 mV/fA. The standard probe sent with each unit is the 100 M>Ω/10 G>Ω version, but other values can be selected.
