Lei-Tech LK-HXBPRO Live-Cell Incubation Workstation

Overview

The Lei-Tech LK-HXBPRO Live-Cell Incubation Workstation is a compact, benchtop environmental control system engineered for real-time optical observation and long-term cultivation of mammalian cells, primary cultures, and sensitive biospecimens under precisely regulated temperature and humidity conditions. Unlike conventional incubators designed for static storage, the LK-HXBPRO integrates an optically optimized chamber with minimal thermal mass and low-vibration air circulation—enabling stable microenvironmental control during live-cell imaging on inverted microscopes. Its measurement architecture relies on high-resolution platinum resistance thermometers (PT100) and capacitive humidity sensors, coupled with PID-controlled heating elements and solid-state humidity modulation, ensuring continuous feedback-driven regulation without condensation risk. The workstation is specifically calibrated for compatibility with transmitted-light microscopy (phase contrast, DIC, brightfield) and fluorescence modalities requiring minimal thermal drift and refractive index stability in the specimen plane.

Key Features

• Benchtop footprint (128 × 86 × 22 mm internal chamber) designed for direct integration beneath objective lenses or within microscope stage enclosures.
• Air-cooled thermal management system eliminating water lines, refrigerants, or external compressors—reducing contamination pathways and maintenance overhead.
• Temperature control from ambient (RT) to +65 °C with uniformity and stability both rated at ±0.1 °C, validated per ISO 17025-accredited procedures using traceable NIST-calibrated probes.
• Humidity regulation across 5–95% RH range with ±3% RH uniformity and stability, achieved via closed-loop vapor saturation control—not evaporative wicking—to prevent localized dew formation on optics or culture vessels.
• Optically transparent front and top panels fabricated from low-autofluorescence, UV-stabilized acrylic with anti-reflective coating (400–1000 nm transmission >92%), minimizing imaging artifacts.
• Passive thermal shielding and vibration-damped mounting interface to suppress mechanical coupling from microscope stages or adjacent equipment.

Sample Compatibility & Compliance

The LK-HXBPRO accommodates standard microscopy-compatible sample carriers including 35 mm glass-bottom dishes, µ-Slides (ibidi), chambered coverslips, and custom microfluidic chips up to 15 mm height. Chamber geometry permits unobstructed access for objective immersion (including 60×/100× oil and water objectives) and side-port illumination. All wetted surfaces are constructed from medical-grade stainless steel (AISI 316L) and silicone-free elastomers compliant with USP Class VI and ISO 10993-5 cytotoxicity standards. The device meets IEC 61010-1:2010 safety requirements for laboratory electrical equipment and supports GLP/GMP-aligned operational documentation through optional audit-trail-enabled firmware (v2.3+).

Software & Data Management

Local control is executed via a dedicated embedded touchscreen interface with real-time graphing of temperature/humidity trends, setpoint history, and alarm logs. For integration into automated workflows, the workstation supports RS-232 and USB-C serial communication protocols compliant with Modbus RTU and ASCII command sets. Raw sensor data (1 Hz sampling) can be streamed to third-party acquisition platforms—including MetaMorph, Micro-Manager, and LabVIEW—enabling synchronized logging with image timestamps. All configuration changes and environmental deviations are timestamped and stored internally for ≥30 days, satisfying basic FDA 21 CFR Part 11 record-keeping prerequisites when deployed with user-authenticated login (optional license required).

Applications

• Time-lapse confocal and widefield fluorescence imaging of GFP-tagged cytoskeletal dynamics under physiological humidity.
• Long-duration single-cell tracking assays requiring sub-0.2 °C thermal stability over 72+ hours.
• High-content screening of stem cell differentiation where ambient humidity fluctuations induce spontaneous osmotic stress artifacts.
• In situ monitoring of organoid maturation in collagen-Matrigel hybrids under 45–60% RH to mimic interstitial tissue hydration.
• Calibration validation of environmental sensors used in ISO Class 5 cleanroom bioreactor monitoring systems.

FAQ

Can the LK-HXBPRO be used with CO₂-dependent cell cultures?
No. This model provides temperature and humidity control only; it does not include CO₂ regulation or gas mixing capabilities. For CO₂-sensitive applications, pairing with an external gas controller and sealed chamber adapter is required.

Is the chamber compatible with inverted microscopes equipped with motorized Z-focus?
Yes. The 22 mm vertical clearance and low-profile base allow full Z-axis travel of standard motorized nosepieces without collision. Optional magnetic alignment fixtures are available for repeatable positioning.

What is the recalibration interval recommended for sensor accuracy?
Lei-Tech recommends annual verification using NIST-traceable reference standards. Factory calibration certificates (ISO/IEC 17025) are provided with each unit shipment.

Does the system generate electromagnetic interference that could affect EMCCD or sCMOS detectors?
No. EMI emissions were measured per CISPR 11 Group 1 Class B limits; radiated emissions at 1–1000 MHz remain >20 dB below threshold across all operating modes.
