CellStor® Freezing Bags

The Cryopreservation Bags are used for the storage of Blood & Blood Components, Cell & Cellular Components and Tissues

  • Efficient Design – Low dead volumes, high recoveries
  • Closed System
  • Compatible with most standard racking systems
  • Custom Designs Available
  • Gamma Sterile, Single-use
  • In-built bag label area for certain bags
  • Tested for non-toxic, and endotoxin
  • Inert and highly bio-compatible
  • DMSO/DMSO-Dextran Compatible

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.

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 temperatures 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 and preventing cell death/loss during cryopreservation.
  • The 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.
  • Labeling 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.
