Description
DESCRIPTION
The Narishige MF3 Microforge facilitates seamless pipette customization while the tip of a micropipette is visualised. The MF3 offers enhanced microscope performance, giving brighter, higher-resolution observation when compared with the previous models.
The microscope has been re-designed to be compact yet robust. It enables the user to easily position the pipette within the field of view, minimising the risk of the pipette breaking. The customization process is further facilitated by the control knobs located near the microscope. The pipette tip can be customized to suit specific applications via cutting, bending, polishing, and spike formation. The heater settings for each technique are displayed on the screen, and the heater may be turned on/off via a foot switch. The brightness of the LED lamp is also adjustable from low to high intensity.
A versatile tool allowing you to fabricate pipettes according to your requirements
The MF3 is used for the microfabrication of pipette tips, as shown in the images below.
The pipette manipulator unit is used to set the pipette position and move it within the field of view. The XY control knobs beneath the microscope are used for fine positioning of the pipette tip. This design also facilitates the efficient inspection of pipettes, including making measurements of tip diameter and checks for damage.
Improvements in microscope design and usability
The microscope unit has been upgraded to provide a bright, clear field of view. In comparison to previous models, the MF3 offers a brighter, clearer field of view, facilitating enhanced visibility during pipette observation and customization tasks, including cutting, bending, polishing, and spike formation.
In addition to the enlarged lens field of view (*a), enhanced operability is achieved through modifications to the micrometer (*b/c/d). Additionally, misalignment during objective lens switching has been reduced, making it easier to locate pipettes within the field of view even at high magnifications. The MF3 includes 10x eyepieces and 5x/10x objective lenses as standard accessories, with the option to add the MF3-LO50 Objective lens 50x (sold separately) to facilitate fire-polishing of patch pipettes for electrophysiology.
(*a) The field of view area has been expanded by approximately 78%, providing a clearer field of view compared to the previous models with a diameter of 15mm to 20mm.
(*b) An eyepiece includes guides to facilitate the confirmation of micrometer units at each objective lens magnification.
(*c) The new-designed micrometer facilitates the reading of the numerical value indicating pipette diameter (thickness).
(*d) The new micrometer features angle gauge lines marked in 5-degree increments, facilitating precise and consistent angle measurement during pipette bending.
Micrometer readout: 10x eyepiece images (cropped)
* By adding the Objective lens 50x (MF3-LO50, sold separately), pipette observation and processing tasks can be performed with the MF3 at a total magnification of 500x.
* MF3 lenses are exclusively compatible with the MF3. Please note that eyepieces and objective lenses from older Microforge models (such as the MF-830, MF-900, and MF2) are not compatible with the MF3 and cannot be used.
