Read Issues

1 Answer During Fluo4 calcium assays the ligand will be dispensed, read for the first couple of columns. Despite dispensing ligand into the rest of the plate, the software stops detecting mid way through the plate and error message at the end of the run states 'more than one of your reads was saturated'

RE: Molecular Devices - FlexStation 3 Multi-Mode Microplate Reader
0 AnswersI cannot find resources on how to wire and plumb the wash unit and vacuum unit needed to use the wash 8 tool. When I go to wash a plate the wash 8 head dispenses but does not aspirate. I tested the vacuum at the pump. At the pump the vacuum is puling. There is no vacuum pulling at the manifold connection on the vacuum unit box though. I have the vacuum unit box plugged into rs232 on the liquid handler. There is another female plug on the box that is not connected to anything, but I cant find resources on where to connect it.

Can you please help me get my vacuum pulling through the vacuum unit box?

Thank you,

Zero counts

11 Answers Trying to resurrect an LS 6500. Got the elevator working and fixed a printer problem. Now I'm getting H# Count rate too low error when counting. If I switch to just plain cpm I get a count rate of zero. Suspect power supply, but everything else seems to work. Is there a separate HV supply for the PMTs? Any way to test that? I've got lots of instrument troubleshooting/repair experience, just no schematics or service manual make it tough to proceed.

SN is 7067355. It's got the Wyse thin client.
