EG-45


Micropipette Grinder

EG-45:  $3,475.68 † - Discontinued
Minimizes irregular movements on the grinding plane for greater precision.

Narishige's EG-45 micropipette grinder replaces the EG-44 and 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 -- low speeds emphasize greater precision and high speeds for faster grinding. It is equipped with an easily operable coarse and fine movement coaxial manipulator for vertical operation of the micro needle, allowing for extremely precise grinding. A protractor is mounted on the needle holder affixing 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 easier to use than the previous version.

FAQ's

Q: Is the EG-45 suitable for beveling pulled borosilicate and aluminosilicate microcapillary needles with ~.5-1um diameter tips for insect embryo injections?
A: Yes, that is exactly the purpose of the EG-45 (to bevel the tips of glass microinjection needles).

Q: How can I observe the microgrinding process?
A: Since this model that doesn't have a built-in microscope (as compared with EG-402, you can position a dissecting stereomicroscope with sufficient working distance, mounted horizontally or diagonally, so you can monitor the microgrinding process. Our SMT1 stereomicroscope with the boom-stand base option can work for this.

Q: Are there different grinding surfaces available?
A: There is only one surface available with a very fine diamond-impregnated grinding disk. It can do extremely fine polishing. To use it, you will need a long-working-distance microscope to monitor the process. Alternatively, you can order the EG-402, which has a built-on microscope to help.
