<h1 class="blog-h1">A Guide to Improving Your Freeze/Thaw Process</h1>

Developing and validating a robust freeze/thaw process while meeting regulatory guidelines is a multifaceted challenge. The biopharma industry increasingly demands cold chain products and operations. That’s due to the scaling of complex therapeutics, a challenging global supply chain, and growing shipping complexities. Improper freeze/thaw processes can ruin sensitive therapeutics and cell and gene therapies, but the right tools can help you reduce cryo-concentration and bioburden while achieving the best return on investment and the greatest optimization of your process.

<h2 class="blog-h2">Minimizing Risk for Biologics</h2>

Even the slightest temperature changes cans compromise drug product. This includes incidents as seemingly minor as holding a freezer door open to find an inconveniently placed item. Companies can always prevent these incidents to save time and money. For example, biologics in different stages of the freeze/thaw process do not always belong in the same freezer, especially if they require different freeze/thaw and storage rates. Keep temperatures uniform and get the most out of your product by ensuring your freezer is appropriate for each application. Meanwhile, optimizing storage within your freezer is one of the best ways to make sure your temperatures are consistent.

<h2 class="blog-h2">Reducing Cryo-concentration</h2>

Protecting your product during the freeze/thaw process can be delicate. Freeze too slowly, and your proteins may aggregate and degrade. Thaw in a water bath, and you might encounter contamination. Cryo-concentration, where protein is not evenly distributed throughout your frozen container, poses the most common risk to critical product quality attributes. Improper freeze/thaw processes can ruin sensitive therapeutics and cell and gene therapies, but the proper tools can help you reduce cryo-concentration and bioburden while achieving the best return on investment and optimize your process. Some tips and considerations include:

• Ultralow Freezer selection — uncontrolled freezing may result in uneven ice formation and cryo-concentration
• Thawing equipment —thawing rates are just as vital as freezing rates in their impact on products
• Storage container — is your biologic stored in a bottle or bag?
