Manual Microinjector

The Manual Injector is a manual syringe driver for pneumatic or hydraulic control of injection needles or holding pipettes. It is suitable for injecting volumes in the nanoliter to microliter range. It is also widely used as a fluid control device for applications requiring sensitive manual control of the displacement of microneedle contents. The system is constructed from the highest quality parts. The base assembly is black anodized aluminum. A non-rotating Mitutoyo micrometer provides the drive to the gas-tight syringe1. A precision 3-way valve provides a convenient method for filling the fluid line and clearing air bubbles from the line. Teflon tubing, chromatography connectors and a pipette holder2 complete the system.

The injection resolution is dependent on the volume of the syringe that is installed, as outlined in the table below. For example, with a 25 µl syringe installed, one complete rotation of the micrometer (25 divisions) yields a displacement equivalent to a volume of 267 nl and turning the micrometer one division (0.001 in) yields 10.6 nl.

1 Please specify the syringe volume that you will be using. For animal IVF, CRISPR, and Pronuclear Injection Holding applications, a 500 µl or 1000 µl syringe is recommended. The 10 μl syringe will require a special assembly and parts if ordered separately.
2 Unless specified otherwise, a pipette holder for 1mm outside diameter glass will be supplied. The diameter of the pipette holder is 0.25 in / 6.4 mm. For micromanipulators that connot accept this size holder an adapter is optionally available. Please contact Sutter for further information.
