Scanning more than one sample in parallel?
The more samples you have, the less you want to scan your vials for cryostorage manually. The Eppendorf RackScan can read complete storage racks with up to 96 different barcoded vials from the bottom. The scanner software transfers the coded sample IDs to downstream databases.The CryoStorage vial is stored in the ULT freezer.
The RackScan can be equipped with the "s" accessory.
Trying to encode your vessel label?
»Stored vessels must be labeled« – something every lab member agrees on. In reality, you always find some vessels in your freezer without any labeling or with non-readable labeling. Clear labeling is recommended to make reading as easy and as reliable as possible for everyone. Printed labels on vessels in plain writing are the minimum condition for safe reading. The barcode is one step further towards fast and safe sample identification.
A barcode is an optical representation of data which is machine-readable.
Counting dots and squares?
A barcode is an optical representation of data, which is machine-readable. Classic 1D barcodes code data by varying the width of the parallel lines as well as their spacings. Two-dimensional codes (2D) are based on dots, hexagons, rectangles, or other geometric patterns. These codes are also called datamatrix codes.
2D codes are based on the following specifications:
› Finder pattern consists of two constant lines at left and bottom, „clock track“
› The quiet zone surrounds the finder pattern, it should be free of any black-white contrast
› The code can be white on black background or black on white background
