TEC-05X

TEC-05X – Two-Electrode Voltage Clamp Amplifier for recordings from medium and large sized cells

Features:

  • Ideal amplifier for medium size cells such as invertebrate ganglion cells, muscle cells or neuromuscular junction preparations
  • Can be used with sharp microelectrodes, and patch pipettes in the whole-cell and perforated-patch configuration
  • Single electrode recording in BRIDGE mode: True current clamp operation with measured membrane potential and complete cancellation of series resistance (potential electrode)
  • Four-pole BESSEL filter for current
  • Digital DISPLAYS for current, voltage and electrode resistance
  • BUZZ and ELECTRODE CLEAR facility with remote hand or foot switch
  • OSCILLATION SHUT-OFF unit prevents cells from damage
  • From pA to µA – low voltage (±15 V) and high voltage (up to ±150 V) versions available
  • Easy connection to all major data acquisition systems, TTL control of MODE of OPERATION, telegraphing outputs for current sensitivity and filter
  • Now optionally with
    • Dynamic Hybrid Clamp (DHC) Mode – measuring of conductances after APs
    • Voltage Clamp controlled Current Clamp (VCcCC) Mode – Current Clamp experiments at controlled resting potentials
