Here are 2 each used but very nice Scienceware test tube racks. They are 9 1/4" x 11 1/2" x 3 1/4" tall and very clean for used. Slots are 1" square. You are buying 2 racks of multicolor epoxy coated steel. Colors range from blue, green, orange and yellow. I can sell these in singles just message me. Thanks for looking.
