Contour Tank Liners
Single-use tank liners for biopharmaceutical fluid containment and processing
- Form-fitting, snug, virtually wrinkle-free
- Centering indicator for perfect alignment
- VelcroTM hold-open rim for easy installation and filling
- Can be used with Charter dip-tube anchor for bottom draw-off
Overview
Charter Medical's single use, Contour Tank Liners are a cost-effective alternative to dedicated tanks & carboys. Contour liners eliminate the issues surrounding cleaning validation and sterilizing of traditional containers. Most importantly, because they are single use, the problem of cross-contamination between different products is virtually eliminated. One rigid plastic container equipped with a fresh liner can be used to process and mix a variety of different products. All Contour Tank Liners are non-cytotoxic, non-pyrogenic, and meet the requirements of the USP Class VI Biological Test for Plastics. Some common applications are:
Typical applications include:
- Diagnostic Reagent Preparation
- Buffer & media preparation
- Mixing and/or compounding prior to sterile filtration

Features and Benefits
Design Features
During mixing, the homogeneity of the product can be jeopardized by the presence of wrinkles in the liner. Wrinkles create pockets that can harbor the additives and shield them from mixing. Later, when the fluid is removed from the container, the unblended components unload from the pockets and alter the concentration of the batch. Charter Contour Tank Liners are designed to minimize wrinkles, and are the most form-fitting available.
Centering Indicator
If a liner is not properly centered, the film will "stand-off" from the wall of the tank and create wrinkles on the opposite side. This stresses the freestanding plastic and provides an unsupported surface that can be more easily punctured. Charter Bio contour tank liners have a centering indicator on the bottom of the liner that helps the operator keep the liner centered in the tank during the critical first few minutes of product fill.
Fit
All Contour Tank Liners fit into standard industry containers with unparalleled snugness. The unique hexagonal weld pattern makes them truly form-fitting, and the diameter of the liner very nearly matches that of the tank.
Since this makes it impossible for the bag material to be pulled over the tank rim, carefully located flaps on the liner extend up and over the container rim. The flaps secure on the outside of the tank with VelcroTM and keep the mouth of the bag open during product fill. A single operator can easily install a liner in any size tank in just a few minutes.
Dip-Tube Anchor
Charter's accessory Dip-Tube Anchor provides uniquely effective bottom draw-off. It allows mixing in an open container, and easy removal of fluid. Since it's anchored, there are no more worries about free-floating tubing suctioning to the side of the liner. Contour Tank Liners are part of the Charter Bio family of biopharmaceutical processing products. Other products include a range of high quality EVA and LLDPE bags designed for sterile fluid containment (Bio-Pak® Small Volume Containers , Bio-Pak® XL), as well as Syringe Access Sampling devices.
Construction
Contour Tank Liners are manufactured from Charter's CPL-613 2 layer composite film, welded in a unique hexagonal pattern for a perfect fit. The fluid contact layer is made from linear low-density polyethylene (LLDPE). This layer is bonded to a multi-layer composite barrier film. The proprietary barrier film layer provides added strength and has very low gas and moisture vapor permeability. Manufacturing of the Contour Tank Liners is performed under cGMP's in an ISO Class 7 clean room. All production occurs in a FDA registered manufacturing facility.
Validation
Contour Tank Liners undergo extensive physical and chemical tests before release. Each liner is shipped with a Certificate of Quality that assures conformance to specifications and lot traceability. The film for our tank liners has been subjected to the following qualification and/or lot release tests:
- USP Class VI Biological Tests for Plastics
- USP Physico-Chemical Tests for Plastic Containers
- Cytotoxicity (Elution Test)
- Hemolysis
- USP Bacterial Endotoxin
- Gamma, dose verification
