Without a Plate Loader
For readers not connected to a plate loader, enter the number of plates in the Num of
Plates field. Then, when you click on Run, you will be prompted to insert the next
plate in the sequence after each plate has been read.
With a Plate Loader (Benchmark Plus and Ultramark only)
Benchmark Plus and Ultramark users can connect their readers to Bio-Rad’s Twister
plate loader. If you have installed the associated Twister software, the Plate Loader
checkbox will appear checked when you first open the Multiple Plate Protocol
window. (If the Twister software is not installed, this checkbox will be unavailable.)
If you do not want to use the plate loader, deselect this checkbox.
With the checkbox checked, when you click on the Run button in the Protocol
window, the Plate Handler Options dialog box will open.
