STEMCELL Technologies STEMvision Colony Counter Unit 3 for Automated Hematopoietic CFU Assays

The STEMCELL Technologies STEMvision Colony Counter Unit 3 is a precision laboratory imaging instrument designed specifically for automated imaging and quantitative analysis of hematopoietic colony-forming unit (CFU) assays. Ideal for molecular diagnostics and bioprocessing workflows in biotechnology and clinical research, it supports single 6-well SmartDish plates with assays for both human and mouse CFUs.

Key technical features include:

• High-resolution CCD digital camera with macro lens and mechanical focus adjustment for sharp imaging of colony morphology.
• Integrated adjustable LED ring illumination ensures uniform, shadow-free lighting critical for accurate colony differentiation.
• A motorized plate carrier enables smooth, repeatable positioning of 6-well plates, enhancing image consistency and throughput.
• Built-in heating system maintains optimal incubation temperature during imaging, critical for colony growth preservation during analysis.
• Manual fine focus control allows precise adjustment supporting high-quality image capture essential in synthetic biology and cellular assay standardization.
• Safety door sensor prevents operation when the instrument access panel is open, ensuring user and sample safety.

Performance and application:

• Rapid assay imaging with approximately 6 minutes per human CFU plate and 3 minutes per mouse CFU plate; fits time-sensitive biomanufacturing and high-throughput screening needs.
• Software suite includes STEMvision Acquisition, Marker, Analyzer, and Mouse Analyzer applications, facilitating comprehensive image capture, marking, colony counting, and subtype differentiation.
• Digital storage of well images supports data integrity and traceability, essential for regulatory compliance in molecular cloning workflows and biomedical engineering research.

Physical and operational specifications:

• Unit dimensions: 480 mm (W) x 335 mm (D) x 347 mm (H) — compact benchtop design suitable for lab spaces with environmental controls.
• Weight: 27 kg (59 lbs).
• Power: Universal power supply (100–240 V~, 50/60 Hz, 1.6 A), with a 250V 2A fast blow fuse.
• Operating conditions: 15 - 30°C and 20% - 85% relative humidity.

This instrument is extensively tested and serviced by certified technicians to ensure full functionality prior to shipment, with warranty coverage and remote setup/training included for smooth integration into research labs. It is widely adopted in clinical diagnostics, stem cell biology, and hematology research, supporting automated CFU scoring that reduces manual variability and increases reproducibility in colony counting workflows.
