MTC Bio’s new BowTie™ Biohazard Bags apply a modern touch to a basic lab necessity that hasn’t been improved in decades. These clearly marked bags are equiped with an exclusive easy-pull drawstring. They also include a sterilization indicator area that changes color after autoclaving, for foolproof verification of sterility. Bags are clearly marked with biohazard symbols and includes a large white marking area for custom identification. BowTie™ Bags are made of HDPE and are suitable for autoclaving at 121°C cycles.
