MP-500 Micropipette Puller

Overview

The MP-500 Micropipette Puller is equipped with a color touchscreen and preset programs, making the production process of micropipette more reproducible and convenient. Its horizontal integrated operating arm structure, softening point testing, safe mode heating, and system diagnostic functions collectively ensure ideal pulling conditions, thereby achieving stable pulling with the microelectrode puller.

Applications:

Microinjection or microelectrode: Cranial injection, Intravitreal injection, Insect injection, C. elegans injection, Embryo injection, Cell injection, Embryo Electroporation, Zebraﬁsh Embryo injection ;
Others: 3D print nozzle, Cell capture , Microﬂuidic;

Features:

Its electrode resistance stability has been improved by at least 10%.
The horizontal integrated manipulation arm structure reduces assembly errors and enhances experimental experience.
Glass tube position scale marking facilitates the simultaneous extraction of two electrodes with identical length.
Its enlarged and more eye-catching buttons, along with extended levers, make operation even easier.
The unique position scale marking and the fixed position design of the heating filament makes it easier to replace various models of filaments.
According to the type of capillary glass, heating filament, and the type of microelectrode to be pulled (e.g., intracellular recording microelectrodes), the corresponding pull protocol is provided as a reference and can be modified according to specific requirements.
The integrated plug-in humidity control chamber is easy to disassemble. The chamber can keep the air around the filament and the capillary glass dry during the pulling process, which can avoid the adverse effect of humid air on the pulling result.
The one-button glass softening point test function is displayed directly on the main interface for customer convenience.
The safe heat mode can avoid the damage of the filament from high temperature.
The preheating and constant temperature function can reduce the influence of the accumulation of jaw heat on the consistency of the pulling results during continuous pulling.
Every time, two microelectrodes with symmetrical tips are produced stably, featuring a tip diameter of less than 0.06 micrometers (μm), a taper length ranging from 3 to 15 millimeters (mm), and a resistance value with high repeatability, spanning from 1 to over 100 megohms (MΩ).
The system diagnostic function can be used to automatically check whether all components of the puller are in normal working condition.
The copy-and-paste function makes it easier to copy existing programs. It can store 150 user-defined programs.

Advantages

Heating filament

The positional scale marking and the fixing slot for the heating filament facilitate the installation of the heating filament.

The integrated plug-in humidity control chamber

An integrated plug-in humidity control chamber facilitates the disassembly process, reducing the time cost for replacing heating elements; it also avoids the adverse effects of damp air on the drawing results.

Built-in pull program

Three-step setup to recommend parameters, lowering the usage threshold and reducing the time cost of preliminary experiments.

The RWD Micropipette Puller is highly stable for pipette pulling in injection-related experiments, and it's easy to operate. The built-in pull protocol and safe heat mode are very useful, which not only improve efficiency but also ensure the safety of the puller. Overall, it's been a great experience.

With pre-set pull protocols, it's easy to set the parameters such as the length and tip diameters of the pipettes with RWD Micropipette Puller. And compared with the pipettes we used before, RWD's is stronger, which makes them much more suitable foon microinjection.

The best thing about the RWD Micropipette Puller is that there are pull protocols for various pulling modes, so you don't need to fumble with various parameters. It's easy to get started, and it can also automatically measure the softening point of the capillary glass. Pulling capillary glass process is fast and consistent, with each micropipette having a consistent tip thickness and length.

Nanjing Medical University

Using the RWD microelectrode puller, a glass electrode with a tapered tip and a 10μm aperture was pulled. In this study, the tapered-tip design design resulted in almost perfect (100%) reproducibility for the production of monodispersed microdroplets compared with ∼20% reproducibility in flat-tip devices.
