On occasion, due to minor discrepancies in manufacturing processes, a test tube may not fit easily into the test tube rack. If you have 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. Contact the customer support team to obtain a replacement test tube rack.
