Test Tube Rack (Support 12 Test Tubes)
 Descriptive 
  42 x 6.5 x 9 cm 
  Wooden test tube rack 
  The wooden test tube rack has 12 slots and 12 drying pegs, to support 10 test tubes up to 22 mm and 2 test tubes up to 28 mm. 
  A test tube rack is used in a chemistry laboratory to store test tubes, either dry or containing some chemicals (waiting for further operations). Since a test tube has a rounded bottom, it cannot stand by itself and thus the rack is a convenient and necessary piece of laboratory equipment for storage of test tubes
