The Labnet Pop-Stopper by Labnet International is an accessory for Labnet digital dry bath blocks that hold microtubes. Labnet lists it for the 48 x 0.2 mL PCR tube block, the 24 x 2.0 mL block, the 24 x 0.5 mL block and the 24 x 1.5 mL block. As the name says, it is used to stop tube caps popping open during heating, protecting samples in routine incubations.
