The versatile range of Celsius® Pak Pre-Designed Solutions (PDS) provide single-use freeze & thaw solutions for every process step when frozen storage and frozen shipment are required. Celsius® Pak PDS are configured with the features needed to decouple downstream process steps and securely transport drug substances to drug product sites.
Celsius® Pak PDS are qualified against extensive biological, chemical,physical, extractable and functional testing. You can use our intuitive digital brochure to select your Celsius® Pak PDS in a few seconds. PDS help speed up process design, reduce the numbers of stock keeping units (SKU’s) and hence reduce inventory management complexity and costs.
The performance and assurance of supply of PDS are based on the complete control of our manufacturing process for the resins, the film, the bags, the filters and the assemblies. Other fluid-contact components are secured by strategic partnerships, long term contracts and quality agreements and are available off-the-shelf to provide best delivery reliability.
Celsius® Pak are available in sizes of 1 L, 2 L, 8.3 L and 16.6 L nominal fill volume and feature a variety of connections to allow fluid transfer across the entire drug manufacturing process.Inlet and outlet connectors
