Application: Lyophilisate retainer, method of manufacturing thereof and procedure of drying a substrate (Patent ID: US20230346641A1)

The patent filed by F. Hoffmann-La Roche Ltd. describes a lyophilisate retainer for lyophilizing a substrate, consisting of a three-dimensional scaffold body with pores designed to receive and hold the substrate. The scaffold material of the body has heat transfer properties that facilitate heat transfer to the substrate within the pores during lyophilization. The scaffold material is required to have a high thermal conductivity of 5 W/mK or more, be inert, and hydrophilic, with the pores dimensioned based on the surface tension and viscosity of the substrate.

The method of manufacturing the lyophilisate retainer involves equipping the scaffold body with pores through additive manufacturing or drilling, with the surface properties of the scaffold body being treated to ensure hydrophilicity. The procedure for drying a substrate using the retainer includes soaking the scaffold body with the substrate and then lyophilizing it inside the pores of the scaffold body. This process is carried out by placing the retainer into a freeze dryer. Overall, the patent focuses on a specialized retainer design that optimizes heat transfer during lyophilization, enhancing the efficiency of the drying process for various substrates.
