DHS iSC/iSC Pro Cell Imaging and Counting System

Overview

The DHS iSC and iSC Pro Cell Imaging and Counting System is a benchtop, integrated digital microscopy platform engineered for quantitative morphological assessment and rapid, objective cell enumeration in routine and advanced life science laboratories. Unlike conventional inverted microscopes requiring eyepiece-based observation, the iSC series employs a high-fidelity color CMOS image sensor coupled with an embedded LCD display—eliminating ocular strain and enabling ergonomic, real-time visual monitoring directly on the instrument. The system operates on brightfield and phase contrast optical principles, supporting label-free, non-invasive analysis of live or fixed cells across diverse culture formats—including monolayer adherent cultures, suspension bioreactors, organoid chips, and histological sections. Its compact, low-profile chassis is certified for safe placement inside Class II biological safety cabinets (BSCs), minimizing aerosol-mediated contamination during critical cell handling and counting procedures.

Key Features

• Integrated 7-inch or 10.1-inch adjustable-angle LCD display replacing traditional oculars—reducing operator fatigue and enabling multi-user viewing without image degradation
• Modular optical design with interchangeable objectives (4×, 10×, 20×, 40×) and dual-mode illumination: switchable between brightfield and phase contrast optics via mechanical turret
• Stable, cool-running LED illumination system with intensity control (0–100% linear dimming) and >25,000-hour rated lifetime—ensuring consistent photon flux and minimal thermal drift during time-lapse imaging
• High-resolution color CMOS sensor (≥1600 × 1200 pixels, 3.45 µm pixel size) optimized for low-noise acquisition under variable contrast conditions
• Dual-input control interface: responsive capacitive touchscreen + standard USB mouse support—facilitating intuitive navigation in glove-compatible or sterile workflows
• IP54-rated enclosure with BSC-compatible footprint (W × D × H ≤ 280 × 320 × 310 mm) and optional HEPA-filtered air inlet for laminar airflow integration

Sample Compatibility & Compliance

The iSC platform accommodates standard tissue-culture vessels including 6–96-well plates, T-flasks (T25–T225), Petri dishes (35–150 mm), and custom microfluidic organoid chips. It supports both adherent (e.g., HEK293, MCF-7, iPSC-derived lineages) and suspension cell types (e.g., Jurkat, CHO-S, PBMCs) without sample transfer or staining. All hardware components comply with IEC 61010-1:2010 for laboratory electrical safety and meet ISO 13485:2016 requirements for medical device-related instrumentation. Software operation adheres to ALCOA+ data integrity principles; audit trails, user access levels, and electronic signatures are configurable to align with GLP and GMP environments per FDA 21 CFR Part 11 guidance.

Software & Data Management

The proprietary iSC Capture & Analyze Suite v3.x provides automated cell confluency estimation, manual/semi-automated counting (with adjustable thresholding, size filtering, and cluster-splitting algorithms), and time-series image registration. Raw TIFF and JPEG outputs are timestamped and embedded with metadata (objective magnification, exposure time, gain, illumination intensity). Data export supports CSV (for Excel/GraphPad), FCS (flow cytometry compatibility), and OME-TIFF (open microscopy environment) formats. Local storage utilizes encrypted SQLite databases; optional network drive synchronization enables centralized backup and cross-lab collaboration without cloud dependency.

Applications

• Quantitative monitoring of stem cell passaging efficiency and differentiation progression via morphology-driven confluency metrics
• Real-time viability assessment in bioprocess development—tracking aggregate formation, spheroid compaction, and organoid lumenogenesis
• Routine QC of primary tissue dissociates and cryopreserved batches prior to downstream assays (e.g., RNA-seq, functional screening)
• Teaching and training modules in undergraduate and graduate cell biology curricula—leveraging direct screen projection and annotation tools
• Preclinical histopathology support: rapid digitization and annotation of H&E-stained frozen sections for semi-quantitative scoring

FAQ

Can the iSC Pro perform automated cell type classification based on morphology?
No—the system does not incorporate AI-based deep learning classifiers. It delivers deterministic, rule-based segmentation using user-defined parameters (e.g., circularity, solidity, area thresholds) aligned with ISO 21530:2021 for morphometric consistency.
Is calibration traceable to NIST or other national metrology institutes?
Yes—each unit ships with a factory-verified stage micrometer calibration certificate traceable to NIST SRM 1982, covering pixel-to-micron conversion at all supported magnifications.
Does the software support LIMS integration?
Yes—via configurable RESTful API endpoints and HL7-compliant message templates for bidirectional sample ID and result exchange with major LIMS platforms (e.g., LabVantage, STARLIMS, Thermo Fisher SampleManager).
What is the minimum recommended working distance for use inside a biosafety cabinet?
The system requires ≥150 mm clearance above the top surface and ≥100 mm rear ventilation margin; full operational validation has been performed in Thermo Scientific 1300 Series and Esco Airstream cabinets.
Are firmware updates provided free of charge during the warranty period?
Yes—DHS offers complimentary firmware and software updates for the duration of the standard 24-month limited warranty, including security patches and regulatory compliance enhancements.
