Sutter 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 holder 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 25µl syringe installed, one complete rotation of the micrometer (25 divisions) yields a displacement equivalent to a volume of 267nl and turning the micrometer one division (0.001in) yields 10.6nl. Syringe Volume Volume Per Revolution Volume Per Division 10µl 106nl 4.2nl 25µl 267nl 10.6nl 50µl 529nl 21.2nl 100µl 1.06µl 42.3nl 250µl 2.65µl 105.8nl 500µl 5.29µl 211.7nl 1000µl 10.58µl 423.4nl  Please specify the syringe volume that you will be using 2 Unless specified otherwise, a pipette holder for 1mm outside diameter glass will be supplied. The diameter of the pipette holder is 0.25in / 6.4mm. For micromanipulators that connot accept this size holder an adapter is optionally available. Please contact Sutter for further information.
