So we have a Kontes TLC streaker and I love the thing, but sometimes as I'm streaking the plate and sliding the device across the table it sometimes gets stuck and that results in a more concentrated area. I've tried lubricating the bench surface with some vacuum grease, and that helped a little, but I'm still getting inconsistent concentration across the band. Does anyone have any tricks/advice for this? Thanks!
