Pharmacia 2-Pen Chart Recorder 482 These test tube racks are each 10.5" long, 15/16" wide and 1.75" tall with 20 holes each 0.5" in diameter. They appear to have come from some sort of automated apparatus, as they have grooves on their sides that appear intended to run on rails, but they can stand on their own as well. They come with a metal tray that holds all six with a little bit of room to spare.
