Problems solved by technology

The lack of this control can lead to yield losses for biopharmaceuticals on the order of about 5% to 50%
Also, the systems described above cannot be easily scaled up for larger volumes and do not provide proper handling control for the product during freezing, storage and delivery

Abstract

A system and method for bulk freezing is provided. In one embodiment, the system and method for bulk freezing includes a bulk freezing container adapted to hold at least one and preferably a plurality of bags holding a biopharmaceutical liquid. The bulk freezing container includes at least a first and second shelf having corrugations, wherein the second shelf is vertically arranged above the first shelf with the bags disposed between the shelves. The bags and the corrugations of the first and second shelves define a plurality of substantially parallel flow channels through which a cryogenic cold fluid or a warming fluid is passed to freeze and / or thaw the biopharmaceutical fluid. In another embodiment, the bulk freezing system and method includes a bulk freezing container with a plurality of adjacent elongated chambers adapted for holding the biopharmaceutical fluid.

Description

technical field [0001] The present invention relates to systems and methods for bulk freezing / thawing of biopharmaceutical materials, and more particularly to systems and methods for bulk freezing employing bulk freezing containers having A plurality of racks defining a plurality of parallel flow channels adapted to convey a heat exchange medium through the plurality of flow channels for freezing / thaw. Background technique [0002] Biopharmaceuticals are often frozen multiple times in bulk to stabilize the product and build inventory. When biopharmaceuticals are required, frozen product is transferred to fill and finish operations for subsequent thawing and distribution. [0003] Current bulk freezing systems provide for freezing of materials in a variety of ways. In one approach, the bottle or container is simply filled and placed in the freezer. Such approaches are labor intensive and offer little scalability and control of the freezing and thawing process. In anothe...
