Hi all,
I had to make some adjustments to one of our methods after discovering that our pipetting sequence would not work due to movement constraints of our independent channels. Therefore, we added movement of our 0.5mL Matrix Rack from the bottom of the deck to the center of the deck. (the tubes are uncapped and the rack also does not have a lid)
The teaching of the labware using the iSWAP was fine, but when I was teaching it kept saying that 11mm was the minimum grip height for the labware. I ended up keeping it that way originally when using the iSWAP Get Plate (Single Step) function. However, I noticed when picking up the rack, it would pick it up basically at the lip of the rack where the lid would sit if it had one. I think that’s a bit dangerous because I worry that the rack might slip out of the iSWAP if more samples are added due to the weight. When the rack was placed into the correct spot, there were no issues in the X and Y direction, but to reach the proper Z height, the prongs of the iSWAP would get caught on the lip and the iSWAP would get pushed up as it travelled down to set the labware into position.
Referring to the programmer’s manual, I increased the grip height to 13, but I’m still having the same issue (I’m wondering if the grip height is actually going the opposite direction).
How would I make it so it grabs the labware closer to the middle of the rack rather than at the very top? Also can you explain what other parameters to consider besides grip height? The only other thing I can think of is maybe the instrument is considering the labware with a lid on.
Thanks
