CZGY GY-YC45A Air-Bath Constant-Temperature Orbital Shaker

Overview

The CZGY GY-YC45A Air-Bath Constant-Temperature Orbital Shaker is an engineered platform for precise, reproducible incubation and mixing of biological, environmental, and chemical samples under controlled thermal and mechanical conditions. Utilizing an air-circulation heating system—rather than water-jacketed or oil-based thermostatic methods—the instrument delivers rapid temperature equilibration, uniform thermal distribution across the platform, and eliminates risks associated with liquid leakage, corrosion, or microbial growth inherent in water-bath alternatives. Its orbital motion (circular horizontal displacement with a 50 mm diameter) ensures gentle yet effective suspension of cells, microorganisms, or particulate suspensions without shear-induced damage—making it especially suitable for bacterial culture expansion, enzyme reaction kinetics, solubility studies, and extraction protocols where consistent agitation and thermal stability are critical. Designed for routine use in regulated and non-regulated laboratory environments, the GY-YC45A meets fundamental operational requirements for GLP-compliant workflows and aligns with general instrumentation expectations outlined in ISO/IEC 17025 and ASTM E2500 for laboratory equipment qualification.

Key Features

• Brushless DC motor drive ensuring low-noise operation, extended service life (>20,000 hours MTBF), and consistent torque delivery across the full 40–280 rpm range
• LCD digital interface with intuitive menu navigation, real-time display of setpoint and actual values (temperature, speed, remaining time), and password-protected parameter locking
• High-stability temperature control via PID algorithm and PT100 sensor feedback, achieving ±0.5°C accuracy and ≤0.3°C uniformity across the platform surface
• Single-tier 470 × 420 mm stainless-steel platform (AISI 304) with reinforced perimeter frame and anti-slip rubber matting; compatible with standard flasks (50–2000 mL), test tubes, microplates, and custom fixtures
• Robust enclosure constructed from cold-rolled steel with electrostatic epoxy powder coating (film thickness ≥60 µm), providing corrosion resistance and mechanical durability in shared lab environments
• Flexible timing function supporting dual-mode selection: minutes (0–9999) or hours (0–999), with auto-shutdown and audible/visual end-of-cycle alerts

Sample Compatibility & Compliance

The GY-YC45A accommodates a broad spectrum of sample containers—including Erlenmeyer flasks, baffled flasks, centrifuge tubes, deep-well plates, and custom bioreactor vessels—without requiring adapter kits. Its orbital motion minimizes foaming and cell lysis during microbial cultivation (e.g., Escherichia coli, Saccharomyces cerevisiae) and supports aerobic respiration efficiency comparable to larger-scale fermenters. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and incorporates over-temperature and motor overload protection circuits. While not pre-certified for FDA 21 CFR Part 11, its audit-ready event log (time-stamped parameter changes and alarms) and user-accessible calibration offset functions support internal validation per GMP Annex 15 and USP Analytical Instrument Qualification guidelines.

Software & Data Management

The GY-YC45A operates as a standalone instrument with embedded firmware; no external PC connection is required for basic operation. However, optional RS-485 serial output (Modbus RTU protocol) enables integration into centralized lab monitoring systems (e.g., LabVantage, STARLIMS) for remote parameter readout, alarm forwarding, and electronic batch record generation. All configuration changes—including setpoints, timer values, and calibration offsets—are logged with date/time stamps in non-volatile memory. The system retains up to 1,000 event records, accessible via scrollable LCD menu or exported via optional USB-to-serial adapter (not included). For laboratories implementing ALCOA+ data integrity principles, the device supports defined user roles (Operator, Technician, Administrator) with hierarchical access control.

Applications

• Microbial growth studies and seed train preparation in academic and industrial bioprocessing labs
• Environmental analysis: BOD testing, heavy metal leaching (TCLP/ SPLP), and soil/water extract preparation per EPA Method 1311
• Pharmaceutical QC: Dissolution medium conditioning, excipient blending homogeneity assessment, and stability-indicating assay sample agitation
• Food safety testing: Pathogen enrichment (e.g., Salmonella, Listeria) and mycotoxin extraction per AOAC 995.12 and ISO 15741
• Research applications including protein expression optimization, antibody purification buffer equilibration, and nanoparticle dispersion protocols

FAQ

What is the maximum load capacity of the platform?
The platform is rated for continuous operation at ≤15 kg total mass (including flask, medium, and fixture), with optimal performance observed at ≤10 kg for sustained 280 rpm operation.
Can the shaker be used for CO₂-sensitive cultures?
No—this is a non-humidified, ambient-air circulation system without gas regulation; it is unsuitable for CO₂-dependent mammalian cell culture but appropriate for aerobic bacterial/fungal work.
Is calibration documentation provided with shipment?
A factory-issued calibration certificate (traceable to NIM, China) covering temperature and speed verification is available upon request; on-site IQ/OQ services can be arranged through authorized CZGY partners.
Does the unit support external temperature probes?
No—temperature sensing is internal only (PT100 mounted beneath the platform); external probe input is not supported in this model variant.
What maintenance intervals are recommended?
Visual inspection and cleaning of air intake vents every 3 months; annual verification of motor coupling alignment and thermal sensor drift using NIST-traceable references.
