End-to-End Process Solution

The CryoVault® platform provides an end-to-end process solution for your entire freeze-thaw process. The system has been proven to provide robust performance from fill to dispense, and every process step in between.

CryoVault Is An End to End Process Solution

CryoVault® has been designed as a modular system to accommodate a high degree of flexibility for different batch volumes. All system components seamlessly integrate with each other. This allows the end-user to tailor the system implementation to their specific process needs. Meissner’s applications engineering team will assist in this process.

Modular Platform

CryoVault® is a modular freeze and thaw platform composed of four components.

CryoVault Constituent Component Categories
Single-Use Assemblies

The single-use assemblies are rigid HDPE containers with configurable fluid path assemblies referred to as top works. The containers feature a consistent freeze-path length throughout the different sizes to ensure process scalability. Single-use assemblies are currently available in the following volumes:

  • Process Development and Stability Scale
    • 40 mL container (30 mL working volume)
    • 120 mL container (100 mL working volume)
  • Clinical and Production Scale
    • 20 L container (16 L working volume)
    • 100 L container (75 L working volume)

The clinical and commercial production scale single-use containers feature an integrated protective shroud that protects the fluid path assemblies during freeze-thaw, transport, and storage. Each assembly is individually serialized to provide material traceability. The rigid container component is manufactured from a medical grade HDPE resin, which has been rigorously tested, inclusive of the BPOG extractables protocol, and has a DMF. The largest container’s ¼” (6.4 mm) thickness provides exceptional robustness and a burst pressure exceeding 50 psi (3.4 bar), while the 20 L container has a burst pressure in excess of 100 psi (6.9 bar). Although burst pressure is only one facet of overall single-use system integrity, providing these values is a good indication of the industry step change in robustness that CryoVault® offers.

Material Handling Components

Material handling infrastructure is one of the most overlooked components of any single-use systems implementation, and it is especially critical for freeze-thaw applications. Meissner offers a wide variety of pre-qualified material handling solutions for CryoVault® at various scales of implementation. These include:

  • Automated lifts and pallet handling solutions that facilitate programmable and repeatable material transfer between various process steps
  • Integrated pallets that can accommodate up to 300 L of liquid in a euro-pallet footprint
  • Carts designed specifically for transport, fill and dispense operations

Freeze-Thaw Components

There are two primary clinical and commercial production scale freezer options for the CryoVault® platform. The large scale freezer can accommodate up to four containers of 100 L, totaling a 300 L nominal working volume, or sixteen single-use containers of 20 L, totaling 256 L of nominal working volume, or any combination of 100 L and 20 L containers. The smaller scale freezer is available to accommodate up to a 96 L nominal working volume or six single-use containers of 20 L. Both freezers are programmable to provide fully controlled freeze and thaw cycles. Agitation, provided via gentle oscillation, is available for thawing sensitive proteins and expediting the thaw process.

Distribution Components

Shippers, which are designed to provide robust distribution performance, are a key component of the CryoVault® platform. These shippers are robust, and are designed to ship on commercial aircraft, which provides more transportation options than those that can only fit on dedicated freight airplanes. These shippers have been tested per ASTM D4169 and ISTA 3E protocols.

CryoVault® Freeze & Thaw Platform FAQs

CryoVault® is a next generation, single-use freeze/thaw platform, primarily directed at critical high value process fluid such as bulk drug substance. It provides a real change in terms of scalability and robustness compared to current solutions. 

There was an industry need for a freeze/thaw solution that was single-use, robust (offered greater security than existing systems), and was scalable to large volume, particularly with the proliferation of decentralized Drug Substance (DS) and Drug Products (DP) processing sites.

Cryovessels have been the predominant technology. However, with recent adoption of single-use systems, new technologies such as biocontainer assemblies (bag assemblies) with outer support containers are available for freeze and thaw applications.

The advantage of a cryovessel system is that you can process large batches. The disadvantage or area for improvement is that the cleaning, sterilization, and validation of these systems require extensive infrastructure and labor to maintain.

Single-use film-based products have all the advantages of single-use, but there can be integrity issues during freeze and thaw. Thin films are fragile and susceptible to tears during material handling processes. In addition, scalability is a big challenge, as the largest volume options include 16-20 L per system. Large scale BDS volumes require proper material handling throughout the F/T cycle. 

CryoVault® is an end-to-end (E2E) platform solution that addresses the common challenges associated with bulk drug substance F/T operations. CryoVault® containers feature a rigid wall with customizable top works that, together, create a complete single-use assembly. The storage containers are modular in size and are available in sizes of 100 L (75 L nominal), 20 L (16 L nominal), 6L (5 L nominal) and 1.25L (1 L nominal) to provide operational flexibility.

CryoVault® is a single-use system for controlled freeze/thaw with all the benefits of single-use and all the features and robustness that you would get with a more traditional rigid cryovessel.

The key differentiator is the science behind the container design. There was intentional design around how bulk drug substance freezes and thaws. It was important to create consistent freeze path lengths, which is easier to control in a rectangular design than in a circular shape like a carboy.

Controlling the last point of freeze has a direct correlation to product integrity by preventing cryoconcentrations, and container integrity by preventing pressure buildup due to ice bridging. Consistent freeze path lengths permit scalability as more BDS can be put into larger containers while freeze/thaw performance remains the same. This provides a faster freeze/thaw cycle, which is critical from an operations perspective.

CryoVault® has been adopted by over 20 locations globally. Our clients realize that this is a unique solution for an obviously critical process step in the customers’ processes and rightly so, there is a high level of vetting by potential users.

Most single-use systems contain multiple polymers, which makes recycling nearly impossible. CryoVault® containers are made from a single plastic material, HDPE, which is a very recyclable material accepted by most waste streams. Of course, there must be a decontamination step first, but companies can work with their municipalities to explore recycling options.

The CV300 platform allows for batch freeze and thaw of up to 300 L of BDS using 100 L, 20 L and 6 L container sizes for enhanced operational flexibility. Similarly, the CV96 platform allows for batch freeze and thaw of up to 96 L of BDS using both the 20 L and the 6 L containers. Each of the CV300 and CV96 platforms feature their own F/T units and material handling equipment.
