Axopatch 200B Amplifier
Axopatch 200B Amplifier

Widely accepted as the gold-standard for ultra low-noise patch clamp recordings, the Axopatch™ 200B Capacitor Feedback Patch Clamp Amplifier is the premier microelectrode amplifier for ultra-low noise patch clamp recordings. Incorporates capacitor-feedback technology and active headstage cooling for single-channel recording, while resistive-feedback circuitry is used for two different ranges of whole-cell recording.

MultiClamp 700B Amplifier
MultiClamp 700B Amplifier

The MultiClamp™ 700B Microelectrode Amplifier is a versatile, computer-controlled microelectrode amplifier designed for patch voltage-clamp (resistive-feedback, four ranges) or high-speed current clamp (voltage-follower, three ranges) recording within the same headstage. Many automated functions and effective signal conditioning. Ideal for many applications, including high-speed current clamp (sharp-electrode or field potentials), patch clamp (whole-cell, macro-patch, or excised patch), voltammetry/amperometry, ion-selective measurements and bilayer recordings. Add two more optional headstage (voltage-follower) inputs for a four-point recording system, ideal for complex synaptic recordings. Major new features of the MultiClamp 700B Amplifier include Internal Automatic Mode switching, triggered by external signals or the recording itself; Oscillation Suppression for better cell protection; and Slow Current Injection to compensate for drifting potentials.

Axoclamp 900A Amplifier
MultiClamp 700B Amplifier

This amplifier features many enhancements that improve its recording capability, make the amplifier easier to use, and your experiments last longer. The Axoclamp 900A Microelectrode Amplifier provides the following modes of operation:

  • I-Clamp: Current clamp using two independent bridge amplifiers for voltage measurements
  • DCC: Discontinuous current clamp for accurate voltage measurements, even when the electrode resistance changes
  • TEVC: High-compliance two-electrode voltage clamp for Xenopus oocytes and mammalian cells
  • dSEVC: Discontinuous single-electrode voltage clamp for small cells with large currents
  • HVIC: High-voltage current clamp for extracellular applications such as iontophoresis

Data Acquisition Hardware / Digitizers

Digidata 1550B plus HumSilencer
Digidata 1550B plus HumSilencer

While offering the same digitization capabilities as its predecessors, the Axon Digidata 1550B Low Noise Data Acquisition System offers up to four HumSilencer channels. This innovative feature allows scientists to record multiple cells simultaneously for higher throughput or cellular network studies without 50/60 Hz line-frequency noise. With only a single click, eliminate the noise obscuring your biological signals of interest and simplify your workflow.

What is HumSilencer?

HumSilencer is an advanced feature that learns, adapts, and removes local 50/60 Hz line-frequency noise patterns and high-frequency harmonics from incoming signal. With a simple ON/OFF check box in Axon AxoScope or Axon Clampex software, HumSilencer enables subtraction of line-frequency noise from your signal.
