The Microforge is a unique device to fine finish for microelectrode tips in patch clamp is assured with advanced fire-polishing technology which eliminates imperfections on the tip surface that could damage delicate membranes.

Many years Narashige developed very successfully two models: the MF-830 and the MF-900. Patch clamp laboratories all over the word made good experience with either model, so as we did ourselves.

The new model MF-2 combines all advantages of both previous models with new technological features.  It is available from October, 2020!


Multiple functions for making different kinds of microtools.

The MF-2 offers a wide range of functions for making many different kinds of microtools by processing micropipette tips. It has heater and lamp adjusting dials on the front, and independent manipulators for positioning the heater and microelectrodes.  The heater manipulator allows fine vertical adjustments, making it possible to achieve a closer, more precise approach to the electrode.  The easy-to-use manipulator is provided for operating the heater and pipette, and the microscope is operated three-dimensionally with control close to the operator's hand. Separate rotation mechanisms for vertical and horizontal movement allow the pipette to be approached at any angle, while a special device in the heater section can form it into any required shape. As well as conventional scales, a protractor to measure angles is provided on the microscope eyepiece. With the heater turned ON/OFF via a foot switch, and the heater section integrated into the microscope body, all control actions are performed easily and precisely close to the operator's hand.
