Narishige's EG-402 replaces the EG-401. It includes a built-in microscope to observe the pipette at contact with the grinding plane. The EG-402 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.

This model provides stable performance at both lower speeds for more precision and higher speeds for faster grinding. The unit includes a coarse and fine movement coaxial manipulator, for vertical operation of the micropipette, which enables 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. 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.

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 grinding 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: 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-401, which has a built-on microscope to help.
