Constructed from polycarbonate (PC) or high-density cardboard, these cryogenic storage boxes are designed for 

low-temperature preservation in liquid nitrogen tanks or ultra-low temperature freezers.

Durable PC Storage boxes: Ideal for short- or long-term cryogenic storage.

Cardboard Storage boxes: Cost-effective solution for temporary storage.

Each PC box lid incorporates alphanumeric grid labels (e.g., A1-H12) for precise inventory tracking and location logging.

Notched corners on PC boxes ensure secure lid placement and precision alignment during handling.

Integrated pressure-equalizing holes allow rapid liquid nitrogen infiltration during freezing and safe vapor 

release during retrieval, minimizing thermal shock risks.
