The Narishige EG-402 Microgrinder is an upgraded replacement for the now obsolete EG-401 and features an XY control unit with improved stability.

The microscope is mounted on the EG-402 Microgrinder, which uses a special motor to minimize irregular movements of the grinding plane: confirmation of contact between the pipette and the grinding plane enables grinding to be performed with greater precision. In addition, the EG-402 Microgrinder 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 micropipette, which also enables very precise grinding. A protractor is mounted on the pipette 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.
