True North® freezer boxes are made from a formulated corrugated or thin film polypropylene.

• Ready to use with easy self-assemble boxes
• Moisture-resistant which significantly reduces the chance of mold growth
• Store down to temperatures of –80 °C

With high durability, polypropylene outlasts the cardboard box alternatives that are susceptible to softening and producing dust and can freeze and thaw multiple times without a problem. These boxes are supplied flat-packed, which eliminates the hassle of stacking and reduces the amount of space needed for test tube storage.
