FlipTop™ Hinged Cardboard Freezer Boxes

Pre-Assembled, Color-Coded, Liquid-Resistant.

FlipTop™ Freezer Boxes offer a durable, space-saving solution for organizing and storing cryogenic vials and microtubes. Constructed from recyclable cardboard with a liquid-resistant outer coating, these boxes are designed for ultra-low temperature storage down to -196°C, making them ideal for use in cryogenic freezers and LN vapor-phase storage.

Each FlipTop™ box features an attached hinged lid that eliminates lid mix-ups and ensures foolproof sample identification. Boxes are shipped fully assembled, with your choice of either 81-place (9×9) or 100-place (10×10) cardboard dividers, and include drain slots for added safety and airflow.

For quick visual sorting, boxes are available in white and five vibrant colors, or in a convenient Rainbow Pack of assorted colors. Alpha-numeric grid markings appear on the top, sides, and bottom for consistent and accurate sample tracking.
