Tech Specs
Master Complex 3D Biology at Scale
Bypass 3D imaging bottlenecks. The Castor S combines high-resolution optics with ultra-fast Z-stacking to slash acquisition times, delivering absolute clarity for your organoids and accelerating therapeutic decisions.
Ultra-Fast Z-Stacking
Eliminate severe phototoxicity and slow scan times. The rapid Z-stacking mode maximizes throughput while preserving the delicate health of your 3D models. 
Darkroom-Free Design
Conserve critical laboratory space. The highly compact, enclosed system executes brilliant fluorescence imaging directly on your benchtop. 
Dual Auto-Focus Precision
Secure uncompromising 3D clarity with combined laser and image-based auto-focus, guaranteeing razor-sharp focal planes across automated runs. 
Intelligent Image Stitching
Simplify complex full-well views. Define your target area and let the software automatically capture and seamlessly stitch perfect macroscopic images. 
Universal Consumable Compatibility
Scale your workflows seamlessly. The open-stage architecture is natively compatible with standard multi-well plates, petri dishes, and cell culture flasks. 
Modular AI Analysis Suites
Adapt to any experimental demand. The platform comes pre-loaded with a comprehensive suite of AI-driven analysis modules to seamlessly support your specific quantitative workflows.
Product Details
Engineered for 3D Biological Confidence
Extract absolute clarity from complex 3D models. Scale seamlessly from fundamental organoid phenotyping to advanced patient-derived drug screening on a single, intelligent platform. 
Accelerate Z-Axis Acquisition
Conquer the primary bottleneck of high-throughput 3D imaging. The Castor S maps a full 96-well plate in just 4 minutes (at 10 focal planes per well), automatically rendering precise 2D projections to reveal critical phenotypic details across all focal lengths.
Automate Complex Stitching
Bypass tedious manual configurations. Simply define your scanning range and let the AI-driven system automatically capture and stitch individual frames into a perfect, seamless macroscopic image.
Decode 3D Data with AI
Translate complex 3D morphology into definitive data. Advanced algorithms process messy brightfield and fluorescent images, instantly isolating target organoids to deliver robust, reproducible quantitative metrics. 
Applications
Accelerate Cell Line Discovery
Organoid Phenotyping & Quality Control
Leverage AI-driven image analysis to automatically recognize and quantify critical health parameters. The system generates intuitive pseudo-color maps that provide immediate, scannable insights into organoid morphology and structural integrity. 
Advanced Hybridoma Screening
Extract definitive viability data using AO/PI dual-fluorescence. Map the precise spatial localization of live and dead cells within the 3D structure, while automated brightfield projections instantly calculate total counts, average diameters, and surface areas.
Patient-Derived Organoid (PDO) Drug Screening
Accelerate personalized medicine pipelines. Execute high-throughput drug susceptibility testing on complex patient-derived tumor organoids (e.g., cholangiocarcinoma), rapidly calculating precise IC50 values to predict therapeutic responses and validate clinical interventions.
