HSE-HAI Microdrive 864/2
Offers excellent displacement characteristics, as required for inserting glass microelectrodes during intracellular measurements.
- Spatial resolution of ~1 µm
- Powered by the HSE Microdrive Controller
- Enables vibration-free insertion of microelectrodes into cell membranes
- Remote operation alternative to hydraulic micro controls
The HSE Microdrive 864/2 represents a complete alternative to previous hydraulic micro controls for the remote operation and vibration-free insertion of the microelectrode into the cell membrane.
In addition to the compact construction, a special feature is the backlash-free circulating-ball spindle and the limit switch built into the mechanism. The circulating-ball spindle requires no maintenance and operates virtually without friction, unlike a micrometer spindle with sliding bearing. Freedom from backlash is achieved through the use of factory-selected balls and is maintained through a very long operating life. Absence of sliding friction inside the circulating-ball spindle ensures freedom from the so-called stick-slip effect. As a result the mechanism accurately follows even the slightest displacement settings.
This unit is powered by the HSE-HAI Microdrive controller.
