A well-designed formulation will protect the product from the stresses of freeze drying. It will also ensure a thermal profile that is favorable for freeze drying. BTL has decades of experience designing formulations for all types of products and an extensive knowledge of excipients. Freeze drying cycles should be efficient, reliable and safe for product and personnel. The development of a cycle should be undertaken rationally, using detailing information about the product’s thermal profile and the production equipment. After analyzing your product BTL can design a cycle that meets all these criteria in typically just 3 runs.
