There were 24 questions found in this category:
  1. question Is it possible to use the PC-501A patch clamp amplifier for planer bilayer recording?
    Yes, you can use the PC-501A for bilayer measurements. However, you will need to reconfigure your amp to use the 5101-10GB bilayer headstage since a regular patch-clamp headstage cannot pass the current required to charge the membrane capacitance. One other thing to note, determining bilayer cap ...

  2. questionCan the IE-210 headstages be repaired?
    No, it is not cost effective to repair an IE-210 headstage. It is less expensive to replace it than to repair it.

  3. questionCan the intracellular electrometers (IE-210, IE-251A) be used to study the blood vessel of rat?
    The IE-210 can be used with any cell type that carries a membrane potential or charge. The amplifier is essentially a current clamp with added bridge balance circuitry for current injection.

  4. questionCan the leads in the headstage DIN connector be repaired?
    Yes. While we can make a repair at the factory, it is a simple enough task that the user can make a repair on-site.The connector used for most Warner devices (amplifiers, temperature controllers, etc.) are known as DIN type connectors. They can be opened by removing the set-screw on the side and ...

  5. questionDoes Warner offer a complete electrophysiology system?
    Warner offers a vibration isolation table and Faraday cage, an amplifier, electrode holders, glass capillaries, an electrode puller, bath electrodes, recording chambers and platforms, stage adapters, a temperature control system, and a perfusion control system.Warner cannot supply a microscope, ...

  6. questionDoes Warner sell a rack to hold the LPF-8 low-pass bessel filter?
    Yes. The RAC-14 is a 14" tabletop rack that comes with all the hardware needed to mount an amplifier, filter, A/D board, and other rack-mountable equipment into a single, integrated unit. A grounding point is provided for attachment to a an isolated ground.

  7. questionIs there a way to avoid damaging the IE-210 intracellular amplifier probe/headstage?
    The probe input is not protected against electrostatic discharge, even if the amplifier is in the OFF mode. Therefore, make sure to electrically discharge yourself through a connection to ground before touching the probe.

  8. questionWhat are some examples of cell systems that have been studied using the PC-505BHC patch-clamp amplifier?
    The PC-505B-HC patch clamp amplifier has been used to study human, animal, fungal, yeast, and plant cells.

  9. questionWhat are the differences between chassis and circuit ground?
    Chassis ground is used to connect the instrument case, or chassis, to an earth ground. It is not usually necessary to use this ground point, and not using it can avoid the occurrence of 'ground loops'.Circuit ground is a reference point chosen for the instrument circuit voltages. This reference ...

  10. questionWhat electrode holders are recommended for use with the PC-501A Patch Clamp Amplifier?
    Warner Instruments recommends using the Q Series holders for the PC-501A Patch Clamp Amplifier.

  11. questionWhat equiment is recommended for field and intracellular recordings from hippocampal slices?
    For field recordings from slices, we recommend the DP-311 differential amplifier with active headstage. This amplifier works equally well with both metal microelectrodes and glass pipettes. The DP-311 is also great for extracellular recording, however, it lacks some basic features found in intra ...

  12. questionWhat is the input resistance of the IE-201 intracellular recording amplifier?
    The input impedance of the IE-201 is effectively 1011 Ω (ohm) resistance shunted by a 0.5 pF capacitance. Our newer model IE-210's have 5x1011 Ω resistance (i.e. 5x higher than the older IE-201), also shunted by 0.5 pF capacitance .

  13. questionWhat is the recommended complete system for intracellular studying?
    A system for tissue and whole cells (10 micron spatial resolution) would consist of the following: a. IE-210 unit (64-0039) and possibly an additional headstage (64-0042) b. ESP/W-FxxN holders (64-0964 through 64-0967) c. MM-33R and MM-33L manipulators (64-0055, 64-0056) d. MB/B magnetic base (6 ...

  14. questionWhat is the VA (wattage) of the DP-304?
    The VA is 10 watts.

  15. questionWhat is the VA (wattage) of the DP-311?
    The VA is 10 watts.

  16. questionWhat is the VA (wattage) of the HiZ-223?
    The VA is 10 watts.

  17. questionWhat is the VA (wattage) of the IE-210?
    The VA is 20 watts.

  18. questionWhat is the VA (wattage) of the IE-251A?
    The VA is 20 watts.

  19. questionWhat is the VA (wattage) of the LPF-100B?
    The VA is 3 watts.

  20. questionWhat is the VA (wattage) of the LPF-202A?
    The VA is 3 watts.
