ezPATCH 100A
[Ne-ezPATCH 100A]

The ezPatch 100A is a smart manipulator. It has all the functions of a manual manipulator. In addition, it comes with a computer controlled feedback system so that it can stop precisely after the electrode touches the cell membrane. The system is ideal for patch clamping.

In patch clamp experiments, all users need to do is aim the electrode at a selected cell. A click of a button and the electrode will stop at the surface of the cell membrane in specified speed and pressure (measured by resistance increase). Patch clamp experiments will be consistent and precise once you find the best seal parameters. The seal parameters can be saved for different cell types and shared among lab members.

The control software has many functions that make patch clamp experiments easy and precise. You can excise patches at the predefined speed. With the manual control functions
in the software, you may move the electrode forward or backward as small as 0.1 µm in defined speed. The software can also control multiple manipulators. Therefore users can make seals on the same cell or a few different cells simultaneously.

If drift from the pipette holder/o-ring is a concern, an optional pipette holder clamp can be purchased. It clamps the glass pipette so that the drift caused by the o-ring is minimal.

There is no additional electrical noise from the manipulator since no current is going through the motor when it stops. Friction ensures that the motor does not lose even a micro step gear (50 nm).

The BNC interface box comes with 10 Analog INs and 2 Analog OUTs. A trigger is provided for sync as needed. For the best grounding result, software can control the BNC interface box to be either in float or grounded condition.

The ezPATCH 100A comes with a National Instruments' PCI 6221 DAQ board which is supported by many data acquisition programs such as pCLAMP. If you plan to choose the software, you will not need to purchase an extra data acquisition board.
