Bioprocessing Containers

CellStor® Single-use 2D & 3D biocontainers for more advanced applications, such as tangential flow filtration, diafiltration and in-process mixing.

CellBios^® offers a wide range of custom 2D & 3D Bags (bioprocess bags) for a variety of applications: preparation, storage and transport of bio-pharmaceutical solutions. The biocontainers are available in single layer and multi layer depending on the applications and range of volumes.

Multilayer film utilizes ultra-pure, inert, and virgin ultra-low density polyethylene (ULDPE) for both the inner and outer layers, ensuring product purity. A core layer of EVOH (ethylene vinyl alcohol) acts as a highly effective oxygen barrier. By preventing oxygen from permeating the film, EVOH helps to maintain the sterility of the contents, extend the shelf life of oxygen-sensitive products, and protect the product from degradation caused by oxidation. Manufactured in a clean room environment, CSF513 film is ideal for single-use bioprocessing applications like 2D and 3D bags, bioreactors, and mixer bags.

CellStor® biocontainers for Upstream and Downstream Bioprocess

Downstream processing is the part of a bioprocess where the cell mass from the upstream is processed to meet purity and quality requirements. The isolation and purification of a biotechnological product to a form suitable for its intended use, is termed DSP. Typically, this means recovery of a product from an aqueous solution. The products of biotechnology include whole cells, organic acids, amino acids, solvents, antibiotics, industrial enzymes, therapeutic proteins, vaccines etc. As these products vary greatly in size and nature, different separation principles are required for their recovery and purification.

CellStor single-use bags are used in bioprocessing into the following stages, including buffer preparation

Harvesting – Solid-liquid separation or clarification by centrifugation or filtration.
Concentration – Ultra filtration, diafiltration & precipitation.
Purification – Chromatography.
Formulation – Crystallisation & freeze drying.
Filling – the formulated product is packed and sent to the market for the consumers.

The CellStor single-use system is vertically integrated, closed, and disposable for continuous upstream and downstream bioproduction
