My students are reporting that their test tubes are not fitting into their test tube rack. What should I do?

Updated Jul 16, 2021

On occasion, due to minor discrepancies in manufacturing processes, a test tube may not fit easily into the test tube rack. If a student is having difficulty placing the test tube in the test tube rack, DO NOT force the test tube into the rack. This may cause the test tube to shatter and cause injury. The student should contact the customer support team to obtain a replacement test tube rack.
