FAQ: Labware - Tubes

Difference alphanumeric, 1D and 2D code

The Answer
The Alphanumeric code corresponds with the position of the tube in the rack (e.g. A1). The code is therefore unique per rack. A 1D Barcode is the standard 'barcode' (type 128B). With a standard barcode the data that is stored can only be numerical (i.e. a series of numbers). Custom barcodes are available on request and can contain a prefix of three letters or numbers. The 2D Data-Matrix is an open 2D code and is laser-etched on the bottom of the tube. It consists of a 10-digit number which results in approximately 10 billion different possibilities, guaranteeing (manufacturer) unique codes. Besides the standard 2D Data-Matrix codes, custom 2D Data-Matrix codes are available on request and can contain a prefix of three letters or numbers, resulting in a possible 13-digit code.
