Warning
Your Axopatch 200B must be returned to Molecular Devices for tuning to add a new headstage. Cost is at least $2,450 IN ADDITION to the cost of the new headstage. Please contact Molecular Devices for a quote. AutoMate Scientific no longer sells these headstages.
For Axoclamp-2 & GeneClamp500 Series
HS-2 and HS-2A unity-gain headstages
The HS-2 and HS-2A headstages are used with the Axoclamp and the GeneClamp. 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-2A-x1MGU – Ask
HS-2A-x10MGU
HS-2A-x100MGU– Ask
“M” versions have extended capacitance neutralization range. “G” versions have grounded cases. HS-2″A” series headstages have an extended operating voltage range (±150V).
For Axoclamp 2 Series
HS-4-x1MGU relay-switched unity-gain headstage
HS-4 headstages may be used with the Axoclamp 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.
Optional CV-5 Series Headstages for the GeneClamp 500B
CV-5-100GU patch-clamp headstage (100 mV/pA)
CV-5B-100GU bilayer patch-clamp headstage (100 mV/pA) – Ask
CV-5-1GU macro-patch headstage (1 mV/pA) – Ask
CV-5-100MU voltammetry headstage (100 mV/nA) – Ask
CV-5 headstages operate with the GeneClamp 500. Each headstage has one feedback resistor for current-to-voltage conversion. The transfer resistance of the 100G, 1G and 100M versions are 100 GΩ, 1 GΩ and 100 MΩ, respectively. The “B” version has an extended capacitance compensation range suitable for bilayers. The 100G version is ideal for single-channel recording and vesicular-release amperometry. The 1G version is suitable for macropatch applications. The 100M version is used for fast cyclic voltammetry using carbon-fiber microelectrodes.
EX-1 five-foot (1.5 m) extension cable – Ask
The EX-1 extension cable works with HS-2, HS-2A, HS-4, VG-2 and VG-2A headstages.
Important Notes
- We are now only selling the ‘U-type’ headstages with the threaded white PTFE inert collets, which connect only to HL-U holders, or U-type adapters and model cells.
- All adapters and holders must be ordered separately.
Mechanical Mounting Options
A 4″ (102 mm) long removable insulated mounting rod is provided at no charge with most headstages. Diameter is 5/16″ (7.9 mm) unless 1/4″ or 3/8″ (6.3 or 9.5 mm) is specified by purchaser. Additionally, all headstages include an insulated mounting plate. Many manufacturers of micromanipulators provide custom mounting brackets for Axon headstages.
