CellStor® Single-Use 2D & 3D Biocontainers

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.

The Biopharmaceutical Industry has validated two primary polymers for the contact layer of Single-Use bioprocess bags which to CellBios utilize. The first material is EVA (Ethylene vinyl acetate) which is commonly used for 2D Bags, and Bags for Rocking Platforms. The second and most widely used material is ULDPE (Ultra low density polyethylene) which is used as the contact layer for large 2D bags and 3D 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

Range of CellStor Bags

CellStor Freezing Bags for Bio-process / Cell Therapy Applications

The bioreactor size in the age of single-use biomanufacturing for single use production, currently between 1000 to 2000 litres. Perfusion systems, operate at 500 litres, and compete economically to 2000 litre fed-batch processes.

CellStor biocontainers are available in various ranges (2mL to 2000L) as disposable processing worked its way from less critical steps (e.g. media and buffer storage) to more critical unit operations (cell culture, filtration).
