0 Answers Hello,

In our Lab we have a Delsa instrument, it's nice, but I did not find how to get Hydrodynamic radius manually from the correlation curve. I don't want to get it automatically, I want to get it from the correlation curve. So how can I do it please? Because automatically, it's giving a very strange PDI (2.893e-09).

many thanks,

loud noise

0 Answers I have in the lab a Hema-Tek 2000 that makes a loud noise during use. I know this unit is kinda old, yet it serves it purpose. I was looking for a service manual that I could download so I can troubleshoot this unit. Any information will be appreciated.

1 Answer I have an L8-55 beckman that the other day decided it will no longer spin.

You set up a run and hit auto run and the LED flashes above the auto run button and then shuts down after 15 seconds. None of diagnostic messages light up after this. The vacuum will start and pull down to level but the rotor will never start spinning.

However if you turn on the slow accelertion feature the speed diagnostic light will then flash after pressing the auto run but there is still no spinning.

Any suggestions on things to check?
