Getting Started > Amplifiers > EPC-9/10 Patch Clamp Amplifier
The amplifier gain, compensation and current/voltage clamp mode of Tecella patch clamp amplifiers can be set from
this control panel.
Select
Setup
EPC-9/10 Patch Clamp
to display the EPC-9/10 Patch Clamp control panel.
Amp. No.: Selects the amplifier channel displayed on the panel when a multi-channel amplifier is in use.
Gain: Selects the amplifier current gain.
Mode: Selects voltage- or current-clamp mode. The CC Gain and CC Tau settings determine gain and response
time of current-clamp. Select the Gentle Mode Change option to change mode gently.
Filters: Selects the filter response type and cut-off frequency of the the two low pass filters in the current recording
pathway. Filter 1 has 4 fixed settings, Bessel 100 kHz, Bessel, 30 kHz, Bessel 10 kHz and HQ 30 kHz. Filter 2
can be selected to have either a Bessel or Butterworth response and a cut-off frequency between 0.1 and 16 kHz.
(A Bessel response minimises signal distortion (ringing) after step changes in the filtered signal whereas a Butterworth
response provides a sharper cut-off of high frequencies.)
Cfast: Sets the amplitude and time constant of the fast (i.e. pipette) capacity compensation. Click the Auto button to
automatically set the Cfast compensation. Click the Clear button to cancel compensation.
Cslow: Sets the working range, amplitude and time constant of the slow (i.e. cell) capacity compensation. Click the
Auto button to automatically set the Cslow compensation. Click the Clear button to cancel compensation.
RS Compensation: Sets the response speed and fraction (%) of series resistance compensation. Click the Auto
