1.2 Safety

When operating the device, users should read the section

2-Important information and

security

to avoid injury to the operator and damage to the device during use.

If you have any questions or suggestions on safety, please contact us for after-sales service

support.

The device should be operated and managed by trained professionals!

This device is not intended for medical use. Microelectrodes pulled by

this device should be used only for animal experiments in a laboratory

environment, but not be applied on human bodies in any form.

1.3 Product introduction

The Micropipette Puller consists of a heating assembly, a pulley assembly and an air cooling

system. It can make a single capillary glass softened by high temperature heating and then

pulled into two glass microelectrodes with symmetrical tips. It is mainly used by experimental

operators for patch clamp experiments and microinjection operations in the laboratory

environment in universities, research institutions, hospitals and assisted reproductive

institutions, or used in various application scenarios that require micro-control operations in

industry.

User

Descriptions

Electrophysiology

researchers

From scientific research institutions, hospitals, pharmaceutical

companies and CROs, engaged in patch clamp and other

electrophysiological recording research, using glass

microelectrodes filled with electrolyte solution to collect weak

bioelectric signals such as ion channel current potential.

Microinjection

researchers

From various scientific research institutions and hospitals,

engaged in intracellular injection operation research (including

embryonic stem cell injection, intracytoplasmic sperm

injection, prokaryotic DNA injection, etc.).

Biological researchers

From various scientific research institutions and hospitals,

engaged in cell selection, collection, transfer and other

micromanipulations.

Application in industry

Preparation of liquid flow pipeline and liquid flow control

system in microfluidic chip technology, preparation of nozzles

in new printed circuit and 3D printing technology, preparation

of operating needles in cell cutting and capture systems, probe

production or preparation of particle capture needles in

material science.

1.4 Product Features

The user interface adopts capacitive color touch screen with high sensitivity.

The front panel cover adopts a roller design, which is convenient for users to open easily.

According to the type of capillary glasses and heating filaments and the type of

microelectrodes to be pulled (patch clamp microelectrodes, intracellular recording

microelectrodes, etc.), the corresponding pull protocol is provided as a reference and can

be modified according to special 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 unique fixed position design of the heating filament makes it easier to replace various

models of filaments.

The one-button glass softening point test function is displayed directly on the main

interface for customer convenience.

The mechanical structure specially designed for the capillary glass makes the installation

and removal of the glass more convenient and safer.

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.

Two microelectrodes with symmetrical tips are stably produced every time. The diameter of

the tip can be less than 0.1 micron, the taper length 3-15 mm, and the impedance range

from 1 to above 100 megohm with high repeatability.

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.

The device can store up to 99 pulling programs.
