Overview
The CZGY HY-45 Air-Bath Constant-Temperature Orbital Shaker is a precision-engineered laboratory instrument designed for simultaneous temperature-controlled incubation and uniform orbital agitation of biological samples. Unlike water-bath shakers, this unit employs forced-air convection as the primary thermal transfer medium—enabling rapid temperature equilibration, reduced contamination risk, and simplified maintenance. Its core architecture integrates a brushless DC motor drive system with microprocessor-based PID temperature regulation and digital timing control. The device operates within a calibrated ambient+5°C to 50°C range, delivering high reproducibility in microbial growth studies, enzyme kinetics assays, cell suspension cultures, and molecular hybridization protocols. The stainless-steel insulated chamber, combined with a reinforced acrylic viewing window, ensures structural integrity, thermal stability, and real-time visual monitoring without compromising insulation performance.
Key Features
- Brushless DC motor providing consistent rotational speed across the full 40–300 rpm range with minimal heat generation and extended service life
- Digital segment-type LCD controller with independent dual-parameter interface for precise setting and real-time display of temperature and oscillation time
- Advanced fuzzy PID temperature control algorithm ensuring ±0.5°C accuracy and ±1°C uniformity across the entire chamber volume
- Orbital motion with 20 mm diameter displacement optimized for homogeneous suspension of bacterial, yeast, and mammalian cell cultures
- Single-tier stainless-steel platform (470 × 400 mm) accommodating standardized flask configurations including up to four 1000 mL vessels or twenty-five 150 mL flasks
- Robust thermal design featuring 500 W heating capacity, 100 W drive power, and double-wall insulation with high-density mineral wool
- Extended programmable timer supporting up to 9999 minutes (166.6 hours) for unattended long-term experiments under GLP-compliant conditions
Sample Compatibility & Compliance
The HY-45 supports standard microbiological and biochemical vessel formats—including Erlenmeyer flasks, culture tubes, and disposable bioreactors—without requiring custom adapters. Its air-bath configuration eliminates liquid leakage risks associated with water baths and complies with general laboratory safety standards for electrical grounding (IEC 61010-1). While not certified for ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, the instrument’s deterministic control logic, non-volatile parameter memory, and stable thermal profile support audit-ready documentation when integrated into validated workflows per USP , ISO 13485, or GMP Annex 11 requirements. Chamber materials meet RoHS Directive 2011/65/EU specifications.
Software & Data Management
The HY-45 operates via embedded firmware with no external software dependency. All operational parameters—including setpoints, elapsed time, and status flags—are retained in non-volatile memory during power interruption. The front-panel interface logs last-used settings (speed, temperature, timer) for rapid reconfiguration. For laboratories implementing electronic lab notebooks (ELNs) or LIMS integration, optional RS-232 or analog 0–5 V output modules (available upon request) enable external data logging and remote start/stop signaling. Audit trail functionality requires third-party middleware; however, the instrument’s deterministic behavior and timestamp-independent parameter persistence facilitate retrospective validation.
Applications
- Microbial cultivation (E. coli, Bacillus spp., Pseudomonas) under controlled aeration and temperature conditions
- Protein expression studies involving IPTG-inducible systems in LB or TB media
- Enzyme activity profiling across defined thermal gradients and agitation intensities
- Hybridization reactions for Southern/Northern blotting and nucleic acid probe development
- Cell line expansion in suspension format prior to transfection or bioprocessing scale-up
- Environmental microbiology applications including BOD testing and wastewater inoculum preparation
- Pharmaceutical QC testing of excipient solubility and dissolution kinetics under agitation
FAQ
What is the maximum load capacity of the HY-45 shaker platform?
The platform is rated for a total mass of ≤15 kg when evenly distributed across standard clamping configurations.
Does the instrument support ramp-to-target temperature profiles?
No—the HY-45 implements step-change temperature control only; it does not feature programmable ramping or multi-stage thermal profiles.
Can the shaker be operated without temperature activation?
Yes—users may disable heating while maintaining oscillation by setting the temperature to “OFF” or selecting ambient mode, enabling use as a room-temperature orbital shaker.
Is calibration documentation provided with shipment?
Factory calibration certificates for temperature and speed are available upon request at time of order; on-site calibration services are not included but supported through authorized regional partners.
What maintenance intervals are recommended for long-term reliability?
Visual inspection of drive belt tension (if applicable), cleaning of air intake vents every 3 months, and verification of door seal integrity annually are advised per manufacturer guidelines.
