This topic explains how to check the stacker gripper pressure (internal air pressure) and
how to adjust it.
Compressed air is used to move the clamps that open and close the labware rack
grippers and the shelves that level the microplates. See
page 15 for the location of these components.
Although the required air pressure from your lab is 0.65 to 0.69 MPa (95 to 100 psi), the
BenchCel Microplate Handler down-regulates the pressure inside the device.
Typically, no adjustment is required for the internal air pressure. You might want to
adjust the pressure when troubleshooting Load Plate problems or when you want to
load different labware on the same BenchCel Microplate Handler.
In general, you can set the internal air pressure within the range of 30 to 50 psi. For
plates that are flexible and tend to bend, you should decrease the air pressure. For less
flexible plates, you can increase the air pressure.
For each plate type or application, you should run optimization tests to determine the
best internal pressure setting.
Note: Each stacker has an air pressure sensor, but the air pressure for each pair of
stackers is controlled by one regulator.
Make sure you turned on the air supply at the source (house, cylinder, or pump).
To check the internal air pressure:
1
In BenchCel Diagnostics, click the Controls tab.
2
Click the Jog/Teach tab.
3
In the Stacker Sensors area, check the air pressure value.
