Adjusting the Z-
Tower Height
2
General 2.1
Before the barcode reader can be used with the Gilson Liquid Handler´s robot
arm, the working height of the Z-tower must be changed.
Hardware 2.2
The barcode reader set contains two black anodized (i.e. has a black eloxation
layer) adjustment cylinders (one with a height of 127 mm, one with a height of 175
mm), which aid you in mounting the Z-tower at the correct height. The 175 mm ad-
justment cylinder is used for the adjustment when cooling racks are used. In either
case the appropriate value must be set up in the Gilson Control Software.
Be sure that you have the correct adjustment cylinder (black anodized). The
original gray cylinder has a height of only 124 mm and this may cause prob-
lems when reading barcodes!
The first step in modifying the working height of the Z-tower is to turn the power off
and remove all the racks from the Gilson Liquid Handler´s bed. Move the robot
arms to the center of the bed as shown in
"The Gilson Liquid Handler" on page
8 .
To achieve the 127 mm (or 175 mm when using a cooling rack) height, loosen the
screw on the back of the Z-tower and pull the Z-tower upwards slightly. Place the
black anodized adjustment cylinder between the bottom of the Z-tower and the
floor of the Liquid Handler´s bed. Lower the Z-tower until it sits on top of the ad-
justment cylinder. The scale should then show the value 127 mm (or 175 mm
when using a cooling rack). Tighten the screw and remove the
black anodized
adjustment cylinder.
