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.

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 33% reduction in handling time and less vessels to handle, CellScrew® ensures efficient, high-quality cultivation to prevent batch loss.


Explore our data and application notes to learn about the features in detail.

Scale with confidence: reproducible results across all stages.

The transfer from lab to commercial scale is a time- and resource-intensive process. We help to speed up the scaling process by providing a solution for every step towards accessible therapy.

Available size variants ranging from 850 cm² to 10,000 cm² with comparable process engineering characteristics make it easy for you to scale your cell cultivation process up or down without the need for complex process development. 

Your benefits with the CellScrew®

Cuts hands-on time and vessels

Cuts hands-on time and vessels

Faster work, lower contamination, and more incubator space available.

Scales without changing formats

Scales without changing formats

All CellScrew® sizes share surface and process logic: Develop once, scale unchanged.

Robust, reproducible results

Robust, reproducible results

Defined mixing and oxygen coefficient give reproducible, operator-independent results akin to benchtop bioreactors.

Lower carbon footprint & waste stacks

Lower carbon footprint & waste stacks

PLA and low material-to-surface ratio cut emissions resulting in 90% lower carbon footprint compared to polystyrene stacks.

Short, reliable supply chain

Short, reliable supply chain

Made in Germany with only two raw inputs and a ISO 9001:2015 certified quality management system.

Your first step to simpler adherent cell culture

Save 30% on your CellScrew® Evaluation Pack —
9x CellScrew® mini, TriDock adapter, and optional roller device loaner included. The simplest way to experience fewer flasks, less media, and less handling.

Using CellScrew® in GMP environment

Avoiding the cliff-edge of having to change format mid-journey, the CellScrew® can take you from research through clinical and commercial manufacturing. With the CellScrew® CCT, we’re introducing a configurable closed transfer version for aseptic fluid transfer workflows.

Cell banking

Supports the controlled expansion and maintenance of cell banks to enable consistent downstream manufacturing workflows.

The genius in the bottle

The innovative internal structure of the CellScrew® forms a large growth surface on a small footprint and fosters optimal growth conditions with low shear forces and excellent gas exchange.



Constant and homogeneous supply with oxygen and nutrients facilitate robust cell growth while scaling. Manufactured from plant-based material PLA (polylactic acid), this product also comes with a significant reduction in material use and carbon emissions, making the cultivation of cells more sustainable.
