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 IVF 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
following table. 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.

*Specifications
subject to change without notice.
1)
Please specify the syringe volume that you will be
using. For IVF applications, 500µl and 1000µl
syringes are commonly used.
2) Unless specified otherwise, a pipette holder for
1mm outside diameter glass will be supplied. The diameter
of the pipette holder is 0.25 inches (6.4mm). For
micromanipulators that cannot accept this size holder,
an adapter is optionally available. Please contact
us for further information.
