Product Description
The Freezing Container, also known as a Programmable Cooling Box, is a proven cryopreservation device designed to achieve optimal cell freezing through controlled gradient cooling.
This non-reagent Freezing Container is manufactured from medical-grade polymer materials: the container body is made of polycarbonate (PC), while the lid and internal rack are constructed from pink high-density polyethylene (HDPE).
The container incorporates a proprietary slow-cooling material that delivers an average cooling rate of −1 °C per minute, which is optimal for most cell types. It is suitable for the cryopreservation of common cell lines, primary cells, stem cells, and more, ensuring high post-thaw cell viability.
The Freezing Container requires no reagents, supports unlimited reuse cycles, and accommodates up to 18 tubes (2 mL or smaller). It is stackable, durable, and maintenance-free, with clear graphical instructions printed on the surface for user convenience. Custom lid colors are available upon request.
Dimensions: 123.4 mm (diameter) × 86.8 mm (height).
Storage & Shipping
Store and transport at room temperature. Shelf life: 60 months.
Instructions for Use
Before use, allow the Freezing Container (Non-Reagent) to equilibrate to room temperature.
Open the lid, place the cell cryovials containing cells into the rack slots, then securely close the lid and transfer the container to a −80 °C freezer for 12–24 hours.
After cooling, remove the cryovials from the container and promptly transfer them to liquid nitrogen for long-term storage. The Freezing Container (Non-Reagent) may be stored at room temperature with the lid tightly closed when not in use.
Precautions
This product does not require a Medical Device Production License; relevant documentation is available for download on the product page.
No reagents are required; however, handle the container with care, as it is heavy.
Do not place the container directly into liquid nitrogen. It must first be cooled in a −80 °C freezer before transferring the cryovials to liquid nitrogen.
For safety, wear a lab coat and disposable gloves during operation.
