Lab Equipment Headaches
Posted: Mon Apr 04, 2016 7:02 pm
I don't work in our IT department at work but when a piece of my lab's equipment needs the computer worked on or upgraded, I make sure I'm there because I'm about the only one that's been there long enough to know the ins and outs of the software that makes them function. I'd requested a new computer for our AKTA FPLC (http://www.gelifesciences.com/webapp/wc ... 2/18190026). The one we have is about 12 years old and uses a proprietary software suite called Unicorn. An FPLC is basically an elaborate $60K pump with a UV monitor and a Fraction Collector. We use ours to purify antibodies. This model is very reliable and only needs routine seal replacements and the occasional UV bulb replacement. The computer that was running it was an old XP-32 bit machine. It' had become unreliable and would cause the USB connection between the FPLC and the computer to drop or the random crash. That sucks when you need something to run for 16 to 20 hours at a time. I'd requested a 32 bit machine and got a Lenovo ThinkCentre M series Tiny Desktop (http://shop.lenovo.com/us/en/desktops/t ... ries-tiny/). I can't remember the exact model off the top of my head but as long as it's 32 bit Windows 7, it should work. I've acquired multiple iterations of the Unicorn 5.xx software over the years ranging from 5.01 up to 5.32. I tried installing version 5.22 because it was the version we were running previously with this instrument. After installing the software and rebooting the computer, I turned on the FPLC so it could connect and it flat out refused to connect. I tried multiple times and even tried the 5.32 version that's supposed to support Windows 7. Nothing. There are two services that are supposed to run and they were. The device manager also showed that the FPLC was present. Next we tried installing the software in XP mode but that was also a bust. I then noticed that the Lenovo had no USB 2.0 ports on it. Every port was a 3.0. I went into the Bios and found that we can enable debugging on port 1 to make it a USB 2.0. I tried that and still couldn't get it connect in Windows 7. The IT guy then went and grabbed an older HP Windows 7 -32 bit machine and it worked perfectly. I have never seen software/drivers that are as picky as the stuff GE writes. We spent 4 hours fussing with the Lenovo.
