CellStor Freezing Bags are suitable for cryopreserving biological samples down to -196°C in both the liquid and vapour phases.

CellStor freezing bags are used to freeze and cryopreserve cells (primary cells and cell lines), and cellular components, blood and blood components, tissues, and other biological products such as vaccines, proteins, exosomes, etc. for use in various treatment modalities such as stem cell therapy, CAR-T cell therapy, NK cell therapy, gene therapy, tissue engineering, and regenerative medicine.

CellStor freezing bags are made up of special grade Ethylene-vinyl acetate (EVA), also known as polyolefin. They retain their flexibility even at freezing temperatures and have high puncture resistance.

CellStor freezing bags are resistant to gas and liquid permeation, they facilitate cross contamination-free storage and culture.

CellBios is the first company in the World to offer freezing bags with 50+ different fill sizes and configurations for various applications. Each Freezing bag is available with 10 different port configurations with or without Overwrap bags providing the end user ultimate flexibility in choosing a bag that is most suitable for their application. Further options are available via our custom order process through which we can accommodate most end users’ process needs.

Ranging from 1 ml to 3 Liters

Features

Safe. Economical.

The CellStor freezing bag set is a safe, economical way to process and preserve blood & blood components, cell & cellular components, tissues, and other biologics.

Low Temperature Durability

The freezing bags are made from special Ethylene Vinyl Acetate (EVA)/Polyolefin film, which combines tough, low temperature durability with excellent transparency, flexibility, impact and puncture resistance.

Reduce Contamination

The bag film has good vapour and gas barrier properties, helping to minimize sample cross contamination.

Long Term Storage

The freezing bag is designed to tolerate long term storage at temperature down to -196ºC, the optimal storage condition of cells, tissue, organs and other biologics.

Retains Biological Specimens

The film material is biologically inert which will ensure that the stored biologics are unaltered by their environment.

The closed system bags ensures microbial free environment to the product

Advantages

CellStor bags are pre-assembled, single-use, gamma sterilized, closed systems
Specially designed for controlled freezing, thawing, and long-term cryostorage
Improved design with reduced dead spaces to ensure proper mixing of the sample, forming a homogenous mixture preventing cell death/loss during cryopreservation.
Smooth inner surface of CellStor bag doesn’t trap the cells and helps in maximizing the recovery of thawed product.
Extra-long EVA tubing enables easy sampling for quality control testing.
Needle free connection options help reduce the risk of contamination and leakage. This also ensures a closed system even after disconnecting the syringe.
Hanger holes are provided for easy handling of the bags.
Labelling space is provided for recording sample information.
Two female luers and one male luer are provided as the default port configuration. However, the port configuration can be customized as per process requirements.
Freezing bags are available in 50+ different sizes (from 1 ml to 3 Liters) offering flexibility for use in various applications.
CellStor freezing bags are available with single, dual, and multi-compartment, top and bottom tubes and ports.
Multi compartment bags are designed to facilitate easy sample distribution into various smaller bags (for different QC studies) and larger storage bags in a single filling operation. This reduces the need for multiple manual welds and seals, reducing contamination risk.
Our Freezing bags are individually packed in Tyvek pouches to facilitate aseptic processing.

Bag Validation: THP-1 and CD34+ cells were suspended in 8% dimethyl sulfoxide (DMSO) and frozen in CellStor freezing bags. Cells were thawed and counted, the average recovery of THP-1 and CD34+ cells were found to be 92% and 90% respectively (study acceptance criteria for thaw recovery was ≥ 70%).
