From flexible research to locked-in GMP processes

Early-stage workflows allow change. GMP manufacturing does not. Decisions made during process development can become costly constraints later — especially when open handling and fragmented liquid transfer are built into the system. The CellScrew® CCT integrates closed processing from the start, supporting scalable and contamination-safe expansion.

Built around your process

The CellScrew® CCT is available in 6,000 cm² and 10,000 cm² formats, based on the proven, TC-treated and gamma-sterilized CellScrew® technology.

The customizable cap assembly allows selection of tubing type, connectors, dip tubes, and venting configurations — enabling seamless integration into existing closed processing workflows and GMP-aligned manufacturing environments.

Your benefits with the CellScrew® CCT

Eliminates open handling risk

Eliminates open handling
risk

No open vessels, no laminar flow cabinet dependency, no operator-to-operator variability.

Configurable to your workflow

Configurable to your
workflow

Select tubing type, connector format, dip tube length, and venting configuration.

GMP-ready from day one

GMP-ready from day one

Your process parameters will transfer directly to GMP without redesigning liquid handling around a new format.

Contamination risk maanged by design

Contamination risk managed by design

Closed architecture removes the primary contamination vector in adherent cell culture.

Scales from 6K to 10K without format change

Scales from 6K to 10K without format change

Scale-up from 6,000 cm² to 10,000 cm² carries your closed workflow forward unchanged.

Same surface, less vessels.

CellScrew® is a dynamic adherent cell culture flask that preserves cell biology while dramatically reducing vessel count and footprint.

One CellScrew® 10K replaces 57 T-175 flasks or 12 roller bottles, consolidating capacity into a single format and avoiding system changes while scaling. The compact, lightweight design simplifies routine workflows and leverages operational footprint.

More about CellScrew®

Less vessels = less work, lower risk, optimized space use

Manual labor drives up to 71% of therapeutic production costs¹. CellScrew® cuts 92% of incubator footprint vs. roller bottles, maximizing cultivation surface area. With a 30% reduction in handling time and less vessels to handle, CellScrew® ensures efficient, high-quality cultivation to prevent batch loss.

Applications for the CellScrew® CCT

Vaccines and viral vectors application of CellScrew®
Vaccines and viral vectors

Supports containment from seeding through harvest without requiring dedicated closed processing equipment beyond the vessel itself.

Cell and gene therapy application of CellScrew®
Cell and gene therapy

Removes the manual aseptic steps that introduce the most variability, supporting consistent expansion of HEK293, MSCs, and iPSCs in a format that can be qualified for GMP without process redesign.

Seed train culture application of CellScrew®
Seed train culture

Maintains closed architecture throughout from early expansion to bioreactor seeding, eliminating the open-to-closed transition step entirely.

Cell banking application of CellScrew®
Cell banking

Supports controlled, aseptic expansion and media exchange for master and working cell bank preparation in clinical manufacturing settings.
