Re: [DIYbio] TECAN Evo Clinical - DiTi not properly mounted on LiHa

Hello Rikke,

thank you for your email.. I will try your suggestion, although I am pretty sure that this is not the problem. I clearly remember that at least once I slowly adjusted the Z value so that I come to the point where a crash error appeared. Then I used the Z value corresponding to that just before the crash error appeared. What I have also not mentioned is that the same problem comes up with the original 10 µl SBS tips from TECAN. Furthermore, the funny thing is that after disounting the tip from the LiHa with my hand, the system "thinks" that is a DiTi is still mounted (see second error below) which makes no sense anyway if it thinks that the DiTi is not properly mounted in the first place anyway.

Have you tried dropping the Z height by another couple of tenths? That has worked for me on the past when using off-brand tips.

Hello all,

I have seen that within the group there is quite some expertice on TECAN liquid handling systems so I thought I'd give it a try.

We have a TECAN Evo Clinical liquid handling system and we have purchased 1000 μl and 200μl tips from a provider and fitting SBS tip boxes. The tip positions of the SBS tip boxes did not quite correspond to the ones from the original manufacturer (from TECAN) therefore I had to initiate a teaching of the LiHa, regarding the x, and y positions of the tips in the box as well as the z position for securely mounting the DiTis.

After finishing the teaching session I tried to pick one tip from the SBS box using the "Get DiTi" direct command from the Evoware standard menu. Although the cone went in the tip, mounted it and lifted it up without any problems, I got the following error message from Evoware standard.

I have tried to talk to TECAN helpdesk but after a lot of emails bak and forth it seems they do not have an idea and they suggested we order one of their technicians to look into it on site.

I was wondering whether anyone has had a similar experience and whether there is a way to overcome this problem.

Thank you for your time. 

All the best,
Panos
