Aluminium Cassettes for Cryogenic Transport and Storage of Cell Therapy Bags

When you’re transporting or storing cryogenically preserved cell therapy treatments, protection and integrity are non-negotiable. ColdStash aluminium cassettes are specifically designed to securely hold cell culture within bags during cryogenic storage and transport in liquid nitrogen or vapour phase LN2 environments.

These cassettes provide a reliable, medical-grade solution for maintaining sample safety from freezer to application.

Designed for Cryogenic Cell Therapy Applications

These aluminium cassettes are engineered for use with cell culture bags, blood bags and bag assemblies used in cell and gene therapy workflows.

They are suitable for:

• Cryogenic storage in liquid nitrogen or vapour phase
• Cryopreservation storage of cell therapy products
• Transport between manufacturing, storage, and clinical sites
• Use in standard cryogenic racks, canisters, and freezers

The rigid frame design protects bags during freezing, handling, and long-term storage while optimising storage space inside cryogenic systems.

Why Aluminium Cassettes?

Aluminium offers the ideal balance of strength, thermal performance, and reliability for cryogenic use.

Key benefits include:

• High-quality aluminium construction for durability at cryogenic temperatures
• Maintains bag integrity during freezing and transport
• Lightweight compared to stainless steel alternatives
• Corrosion-resistant and compatible with liquid nitrogen environments
• Designed to protect samples from physical damage and deformation

Each cassette acts as a protective frame, ensuring bags remain flat, supported, and easy to handle throughout their lifecycle.

Compatible with Cryogenic Storage Systems

ColdStash range of aluminium cassettes is designed to integrate seamlessly with:

• Cryogenic racks and canisters
• LN2 storage systems
• Vapour phase and liquid nitrogen storage
• Standard cryogenic freezers

Multiple sizes are available to accommodate different bag formats and storage requirements, allowing you to select the right solution for your application.

Built for Safety, Quality, and Compliance

These cassettes are manufactured to meet the expectations of medical and biotech environments where sample protection is critical.

What this means in practice:

• Secure storage of high-value cell therapy samples
• Reduced risk of bag damage or leaks
• Consistent handling across storage and transport stages
• Confidence in long-term cryogenic performance

They are a practical, proven solution for laboratories, biobanks, and cell therapy manufacturers that require dependable cryogenic storage hardware.

FAQs

What are aluminium cryogenic cassettes used for?

They are used to securely store and transport cryogenically preserved cell culture, blood, and plasma bags in liquid nitrogen or vapour phase storage.

Are these cassettes suitable for cell and gene therapy products?

Yes. They are specifically designed for regulated cell therapy and cryopreservation workflows where sample integrity is critical.

Can the cassettes be used in liquid nitrogen (LN2)?

Yes. They are validated for use in both liquid nitrogen and vapour phase cryogenic storage environments.

What types of bags are compatible?

They are compatible with standard cell culture bags, blood bags, plasma bags, and related bag assemblies used in medical and biotech applications.

How do the cassettes protect cryogenic bags?

The rigid aluminium frame supports the bag during freezing, storage, and handling, reducing the risk of deformation, leaks, or mechanical damage.

Why choose aluminium over stainless steel?

Aluminium provides excellent cryogenic performance while being lighter than stainless steel, improving handling efficiency and storage density.

Are the cassettes compatible with standard racks and canisters?

Yes. They are designed to integrate with standard cryogenic racks, canisters, and LN2 freezer systems.

Do the cassettes help optimise storage space?

Yes. Their flat, structured design allows efficient stacking and organised storage within cryogenic systems.

Are these suitable for regulated medical environments?

Yes. They are intended for professional use in laboratories, biobanks, and cell therapy manufacturing under controlled and regulated conditions.

What sizes are available?

Multiple sizes are available to suit different bag formats. Selection depends on bag dimensions and storage system compatibility.

How are the cassettes supplied?

Cassettes are supplied ready for use in cryogenic environments. Cleaning and handling should follow the user’s internal SOPs.
