Characteristics

NanoFil

Syringe with minimal dead volume

Small volume injection, such as ophthalmic injection

Yes

No

Minimum dead volume; durable and flexible; a variety of needles available in sizes 26-36G, blunt, pointed or beveled needles; used to move liquid to the glass needle or eliminate air bubbles in the glass needle; can be operated manually or with MMP, DMP, UMP3 are used together.

PV830

Vacuum pneumatic skin lift syringe pump

Intracellular injection of picoliter

NO

YES

Pisheng rose to Nasheng

The injection volume is determined by the inner diameter, pressure and time of the tip. Apply to very small intracellular injections. The glass tip can be as small as 0.1 micron. When the glass tip of one side grips the cell, the other side can be injected.

PV820

Pneumatic skin lift syringe pump

Intracellular injection of picoliter

NO

YES

Pisheng rose to Nasheng

The injection volume is determined by the inner diameter, pressure and time of the tip. Apply to very small intracellular injections. The glass tip can be as small as 0.1 micron.

Nanoliter

Microcomputer controlled piston displacement syringe pump

Oocyte injection

No

Yes

2.3–69 nanoliters (related to the volume that the glass capillary can hold). Multiple hundred samples can be injected quickly and repeatedly.

Highly accurate. A total of 2.3 fluids can be injected between 2.3 and 69 nanoliters (up to 5 microliters with the MICRO4 controller).

UMP3

Automatic syringe pump

For intracranial positioning injection

Yes

Yes

Actually: 5–25 nanoliters (using a 10 microliter syringe)

No pulse transfer liquid; easy to install; well-made and durable, precise parameters

DMP

Digital microscopy manual syringe pump

Manual injection of small amounts of liquid

Yes

Yes

From 10 nanoliters to microliters, depending on the syringe used

Accurate, manual operation.

Can use 100 microliters to 1 ml syringe

Digital rangefinder

MMP

Manual syringe pump with macrometer

Manual injection of small amounts of liquid

Yes

Yes

From 10 nanoliters to microliters, depending on the syringe used

Accurate, manual operation.

Can use 100 microliters to 1 ml syringe

SYS-260

Two-way microelectrophoresis current generator

Injection of dyes, drugs or charged substances from micropipettes

No

Yes

Electronic isolator, battery operated

Glass capillary for submicron tip

No need for a transformer, quietly convert ±9V to ±100V output
