Need a variety of sizes of test tubes? Or not sure what size you need? Then here is the auction for you…
This is a set of 7 Assorted Sizes of Test Tubes. You get 3 of each size plus rubber stoppers for a total of 21 test tubes. The sizes included are as follows…

Size is given with  OD (Outside Diameter) first then length. All measurements are approximate. OD measurement may vary by up to 1mm.

This set is especially nice for someone who is not familiar with test tubes and may not know what size they need. It contains a nice range of the more commonly used sizes with their stoppers at a great low price. It is also a great set for Science Projects/Experiments; storing craft items of assorted sizes like buttons, beads, glitter and stones; decorating for Halloween; or for displaying spices. Your imagination is the only limit to their uses. Would also make a nice gift for students studying Human or Veterinary medicine or Science. They are made of heat resistant (borosilicate) glass and will hold up indefinitely to normal everyday use.
