Enriched coding
Based on high-precision printing technology, the tiny space at the bottom of the cryopreservation tube can be used to make 2D barcode graphic as well as corresponding clear code, which can still ensure the accurate access to information in the absence of specialized equipment for reading. In addition, the 1D barcode or corresponding clear code, or specific logo or mark can be made on the side wall, which is the same as the code on the bottom.
