The electrical specifications of the S-Probe are identical to our standard Red Star Headstage. In addition it has the feature of an optional bath sense connection which gives it the opportunity to operate in the 3 Electrode Mode (see below). Contact us to find out if your amplifier is supporting this mode.

The headstage has a thread connector to provide a safer electrical connection of the headstage and the pipette holder.

RMS noise values are:

  • 31 fA @ 1 kHz
  • 72 fA @ 3 kHz
  • 120 fA @ 5 kHz

The headstage can be used either with an EPC 10 (revision ‘O’ or higher) or an EPC 10 USB (revision ‘N’ or higher) or the EPC 800 USB amplifier missing with 3 Electrode mode though. Get in touch with us for details.


  • Dimensions (D x W x H): 49 x 16.5 x 14 mm / 1.92 x 0.65 x 0.55 inch, without connector
  • Weight: 24 g
  • 3 Electrode Mode option
