HS-2 and HS-2A unity-gain headstages


The HS-2 and HS-2A headstages are used with Axoclamp 2 and GeneClamp amplifiers. They are all unity-gain voltage recording headstages but they come in a variety of different current-passing gains for applications as diverse as extracellular recording, bath-potential recording, ion-sensitive recording, ionophoresis and intracellular recording from small or large cells. For ultra-high impedance electrodes, special circuitry inside the headstage prevents any DC current from leaking into the input through the capacitance neutralization circuit.

  • HS-2-x0.0001MU
  • HS-2-x0.01MU
  • HS-2A-x0.1LU
  • HS-2A-x1LU
  • HS-2A-x1MGU
  • HS-2A-x10MGU
  • HS-2A-x100MGU
  • VG-2A-x100 (virtual ground)
"M" versions have extended capacitance neutralization range. "G" versions have grounded cases. HS-2"A" series headstages have an extended operating voltage range (±150V).

HS-4-x1MGU relay-switched unity-gain headstage

HS-4 headstages may be used with Axoclamp 2 amplifiers to maximize the voltage across the electrode during two-electrode voltage clamp. In all other modes the HS-4 acts like an HS-2 headstage. Available only with current-passing gain x1MG. The VG-2 headstage must be used for current measurement.

VG-2 virtual-ground headstage

The VG-2 virtual ground headstage may be optionally used with Axoclamp 2 amplifiers to measure whole-bath current. Standard current measurement gains are x0.1, x1 and x10. x100 is also available. Current recording ranges for these virtual ground headstages are: ±0.1 μA (x0.1), ±1 μA (x1), ±10 μA (x10), ±100 μA (x100).

VG-2A-x100 bath clamp headstage

The VG-2A-x100 bath-clamp headstage may optionally be used with Axoclamp 2 or GeneClamp amplifiers to clamp the bath potential at zero volts. This eliminates the effect of series resistance in the bath grounding electrode and the bath solution. It can also minimize the extent of DC voltage shifts resulting from changes in the bath solution or temperature.

To offer a more conventional interface to amplifier control, the optional SoftPanel was designed as a hardware extension to replicate all essential amplifier functions by acting as a hardware extension to the Axoclamp and MultiClamp Commander Software. The SoftPanel controller communicates with the computer via an easy-to-set up USB 2.0 connection. Using the SoftPanel knobs replicate continuous mouse controls ("gliders"), while buttons replicate single-click mouse controls without negating the many benefits afforded by computer control of the amplifier.
