Narishige's EG-400 is the best unit we offer for high-precision grinding. The EG-400 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-precision polishing. The EG-400 microgrinder includes a z-axis micromanipulator, a water dripping device to provide continuous lubrication and an integral microscope to monitor the grinding process.

Micropipette Grinder

EG-44: $2,486.49 † - Ships in 1-5 days

Narishige's EG-44 micropipette grinder minimizes irregular movements on the grinding plane for greater precision.

This grinder is ideal for grinding micropipette tips, thanks to its employment of a special motor which is designed to minimize irregular movements of the grinding plane. In addition, this model provides stable performance at all revolution speeds -- from low for more precision to high for faster grinding. An easily operable coarse and fine movement coaxial manipulator is equipped for vertical operation of the microneedle, which also enables very precise grinding. A protractor is mounted on the needle holder fixing section, making it easy to set the required grinding angle, and an adaptor is attached for vertical grinding. New water filling and drainage mechanisms are installed to prevent clogging or the accumulation of shavings, making the apparatus as a whole much easier to use.
