3D Cell Culture CEROplates

ceroplate 96 well ultra low attachment u bottom

The ultra-low attachment CEROplate simplifies the process for growing 3D aggregates. It features clear wells with a U-bottom to make sample monitoring simple. The unique well geometry of the microplate aids in the formation of an unattached, round-shaped, single spheroid or organoid in the center of each well.

This allows you to assay and analyze your 3D aggregates in the same plate without transfer. The CEROplates are compatible with existing readers, imaging systems, liquid handling, and automated workstations.

CERO 3D FAQs

Achieving uniform 3D structures requires tight control of environmental conditions and low-shear culture. The CERO 3D incubator and bioreactor provides a controlled, low-stress suspension environment that produces highly homogeneous aggregates without microcarriers or scaffolds.

Long-term viability depends on stable pH, CO₂, temperature, and gentle mixing. The CERO 3D maintains a fully regulated culture environment, enabling 3D spheroids, organoids, and stem-cell aggregates to remain healthy for weeks to months.

Scaling up requires a system that supports large culture volumes without compromising uniformity. The CERO 3D allows expansion of 3D models in up to ~50 mL culture tubes, enabling reliable biomass generation for screening, toxicity testing, and disease modeling.

Traditional shakers and spinner flasks can damage delicate aggregates. The CERO 3D uses a low-shear rotation system that protects developing spheroids and organoids while ensuring uniform nutrient and oxygen exposure.

Reproducibility requires consistent environmental conditions and standardized vessel geometry. The CERO 3D uses identical disposable CEROtubes and closed-loop environmental control to achieve experiment-to-experiment consistency.

Automated mixing and environmental monitoring dramatically reduce manual intervention. The CERO 3D supports “set-and-walk-away” culture with only brief daily checks, helping labs save hours of effort per week.

Higher yields come from stable culture conditions and consistent mixing. The CERO 3D produces dense, viable 3D biomass with minimal cell death, supporting applications such as drug discovery, disease modeling, and regenerative research.

CERO 3D FAQs

What is the CERO 3D Incubator & Bioreactor and what is it used for?
The CERO 3D Incubator & Bioreactor is a rotation-based 3D culture system developed by Cell Microsystems. It is designed for long-term organoid and spheroid culture, supporting stable environmental conditions including CO₂, temperature, and low-shear rotation. CERO is relevant for researchers who need reproducible 3D culture workflows, multi-condition experimentation in a single system, and reduced dependence on large incubator infrastructure.
How does CERO compare to static 3D culture methods such as ultra-low attachment plates?
Static 3D culture methods such as ultra-low attachment plates are widely used and offer a low barrier to entry, but can present challenges for long-term culture health, reproducibility, and management of multiple experimental conditions. The CERO 3D Incubator & Bioreactor uses rotation-based culture designed to support sustained organoid health and stability over extended periods, with self-contained operation intended to reduce infrastructure burden and simplify multi-condition workflows.
What is the best way to maintain long-term 3D cell cultures with high viability?
Long-term viability depends on stable pH, CO₂, temperature, and gentle mixing. The CERO 3D Incubator & Bioreactor maintains a regulated culture environment designed to support the health of 3D spheroids, organoids, and stem-cell aggregates over extended culture periods.
How can I reduce shear stress during 3D suspension culture?
Traditional shakers and spinner flasks can introduce shear stress that damages delicate aggregates. The CERO 3D uses a low-shear rotation system designed to protect developing spheroids and organoids while supporting uniform nutrient and oxygen exposure.
How do researchers scale up 3D cultures for downstream assays or manufacturing?
Scaling up 3D cultures requires a system that supports larger culture volumes without compromising uniformity. The CERO 3D supports expansion of 3D models in up to approximately 50 mL culture tubes, supporting biomass generation for screening, toxicity testing, and disease modeling applications.
How do I minimize hands-on time when growing organoids or spheroids?
Automated mixing and environmental monitoring reduce manual intervention. The CERO 3D is designed to support extended culture with only brief daily checks, helping labs reduce hands-on time per experiment.
