• MATERIAL AND DIMENSTIONS- the sample tube rack is made of solid plastic, sturdy and durable to use; measures approx 250 * 105 * 70mm/9.84 * 4.13 * 2.76"(L*W*H)when assembled
  • HOLDS 24 TEST TUBES - 24 holes, the width of the hole is approx 25mm/0.98", ideal for holding test tubes whose max diameter is 25mm or under
  • DETACHABLE FEATURE- the plastic test tube rack comes 3 separated pieces, assemble required; can be stored put together or taken apart and laid flat, won't take up much more room
  • SIMPLE TO ASSEMBLE - just fold the arms up, and insert the slotted holders and snap them together. It holds together
  • WIDE APPLICATIONS - Work great for test tubes holding beads for jewelry making, holding gumballs/M&Ms/treats/candy/ for christmas gift, holding liquids for lab experiment, ideal for home, school classroom, lab use

Easy to see what you have; each tube holds around 150 beads if around 4mm. Tops sock into tube, no chance of losing beads if tubes fall over.. I have purchase 4 sets of these and if I need more, I will purchase again.

Purchased another rack for large test tubes but holes were too small. This rack is not beautiful but very functional for large test tubes.
