The figure below illustrates the XenoWorks Analog Microinjector fully assembled, complete
with syringe.
Figure 1-2. Analog microinjector controls and features.
1.2.1 Syringe Clamp
This holds the glass body of the syringe barrel gently and firmly in place. See below for notes
on syringe attachment.
1.2.2 Plunger Clamp Screw
This grips the end of the syringe plunger, allowing it to be pushed in and out of the syringe
barrel by the movement of the black sliding block.
1.2.3 Sliding Block
The sliding block is moved along the body of the analog microinjector, moving the syringe
plunger that it grips, in and out of the syringe barrel. The sliding block is moved by rotation
of the micrometer screw (which can be seen running the length of the inside body of the
microinjector). The micrometer screw is turned by rotation of the coarse and fine controls.
1.2.4 Coarse and Fine Controls
Turning the coarse and fine controls rotates the micrometer screw that moves the sliding
block up and down the body of the microinjector and in turn moves the syringe plunger.
Turning either control clockwise moves the syringe plunger into the syringe barrel, pushing
out the hydraulic fluid and injecting the contents of any attached micropipette. Conversely,
rotation of the controls counter-clockwise pulls the plunger out of the syringe barrel and
