Micropipette Grinder

EG-401:  $5,837.84 - Ships in 1-5 days
Narishige's EG-401 replaces the EG-400 and is the best unit we offer for high-precision grinding. It includes a built-in microscope to observe the pipette at contact with the grinding plane. The EG-401 is typically used for beveling glass microcapillary microinjection needles, yielding both a sharper needle and a larger opening. It can also be used for almost any fine polishing operation.

A "whetstone" grinding disk is spun by a stabilized variable-speed motor for either fast grinding or ultra-precise polishing. The EG-401 microgrinder includes a z-axis micromanipulator, a water dripping device to provide continuous lubrication, and an integrated microscope to monitor the grinding process.
