Where do I find the voucher code for free QuantSeq data analysis?

The code can be found on a label located on the cardboard above the microtube holder (Figure 1; or one of the holders, if the kit contains more than one). The microtube holder/s can be found inside the Library Generation Module box (stored at -20 °C).
