12 mm Vial Stepped Rack With Pour Tray
A two-tier rack that holds twelve 12 mm OD screw-cap vials or small test tubes upright, one size of loose M2/M2.5 screws, washers or 0402/0603 passives per tube. The back row stands 12 mm taller so you can read the labels. The 12.8 mm bores have chamfered lead-ins, and a 26 x 100 mm pour tray in front lets you tip out a tube, pick what you need and pour the rest back. The rack is 104 x 74 x 36 mm and the sleeves are hollow to keep material low.
