Eppendorf PatchMan NP 2 - Manual (Page 5)

50
The Eppendorf PatchMan NP 2 micromanipulator is specially designed for use in
electrophysiology, and is marked by extreme ease of operation.
This makes the PatchMan NP 2 the right device for anyone performing electrophysiological
measurements on cells and membrane pieces, as well as being suitable for use as a universal
micromanipulator in many other applications.
The PatchMan NP 2 micromanipulator combines the classic benefits of a mechanical system
(direct feeling for tool movements) with the advantages of a precise motorised system.
The direct adapter attachment of the module unit to all commonly used microscopes (optionally
positioned at the left or right) and the separate control board prevent oscillation and vibration.
The device is adapted to upright microscopes by means of the Eppendorf universal stand.
The tool can be attached to the module unit at any angle and in any orientation.
The PatchMan NP 2 micromanipulator is designed for non-damaging placement of
measurement electrodes on and in the cell. This is aided by the device's facility to approach the
cell membrane extremely slowly. In this, the virtually drift-free mechanism particularly supports
measurements which take longer than 30 minutes. Also, the joystick can be locked to prevent
accident movement. Special features include the ability to execute a purely downward
movement and the position memory.
The changing of pipettes frequently necessary in patch-clamp measurements is made much
faster and easier by the HOME function.
