Overview

This label class provides attributes for Bioscan tube labels. The labels have two stickers, side and cap.

The side contain a 2D barcode image and four text lines.

  • The barcode image contains human barcode.

  • The first line contains parent barcode and well range for PCR2 Pool tube and only the parent parcode for others.

  • The second line contains current tube barcode without prefix and number of pooled samples, the third line contains the labware purpose.

  • The third line contains current tube labware purpose

# The last line contains date of printing.

The cap contains two text lines.

  • The first contains barcode prefix.

  • The last contains current tube barcode without prefix.

Initially, this arrangement was only intended for Traction compatibility of Lib PCR XP (final) tube. However, difficulty of printing 1D barcodes for PCR2 and Lib PCR tubes made us using 2D barcodes for all three Bioscan tubes.

Only Squix printers are used for printing labels for Bioscan labware from Limber. We do not send the print requests to PMB service, instead we send them directly to SPrint service, which talks to Squix printers.
