One wash station consists of three individual 8-fold wash modules IRU WKH VDPH QHHGOH
W\SH: High Volume (1000 µl), Standard Volume (300 µl), or Low Volume (50 µl).
To enable parallel pipetting with an 8-channel Microlab STAR, the following cycle of steps
takes place:
1. fresh needles are picked up from the first module for pipetting, used, and then placed
back into the same module. Washing starts.
2. fresh needles are picked up from the second module for pipetting, used, and then placed
back into the same module. Washing starts.
3. fresh needles are picked up from the third module for pipetting, used, and then placed
back into the same module. Washing starts.
4. The next set of needles is picked up from the first module again, which in the meantime
has washed and dried all 8 needles. The process is repeated again.
The needle wash station needs to be installed by a trained Hamilton engineer.

The carry-over of the wash station depends on the wash program. Typical values are 10

10
-6
.
The wash parameters can be set within the User Software, prior to each wash step.
