CZGY DHZ-CA Horizontal Constant-Temperature Orbital Shaker Incubator

Overview

The CZGY DHZ-CA Horizontal Constant-Temperature Orbital Shaker Incubator is an integrated air-bath incubation and orbital shaking system engineered for precision-controlled cultivation and agitation of biological samples under stable thermal conditions. It operates on the principle of forced-air convection heating combined with smooth, low-vibration orbital motion—ideal for applications requiring simultaneous temperature regulation and uniform mixing without shear-sensitive disruption. Unlike water-bath shakers, this air-bath design eliminates condensation risks, simplifies cleaning, and ensures rapid thermal equilibration across the chamber. Its horizontal configuration maximizes usable platform area while maintaining ergonomic access and structural rigidity during extended operation. Designed for continuous-duty laboratory environments, the unit features a brushless DC motor for consistent rotational speed, minimal electromagnetic interference, and maintenance-free long-term performance.

Key Features

• Brushless DC motor drive delivering stable rotational output across the full 30–300 rpm range, with speed accuracy of ±1 rpm under load
• Superimposed fuzzy PID temperature control algorithm ensuring thermal stability within ±0.3°C at setpoint across the operating range (ambient +5°C to 60°C)
• Single-tier stainless steel shaking platform (1000 × 640 mm) with reinforced edge support and standardized spring-loaded clamping system
• Dual independent timer functions: one for temperature hold duration (0–9999 min), another for oscillation activation (0–9999 min), enabling complex multi-stage protocols
• High-efficiency 1200 W heating element with optimized airflow ducting and insulated double-wall chamber (interior: 304 stainless steel; exterior: powder-coated cold-rolled steel)
• Large front-access viewing window with integrated LED illumination for real-time sample observation without thermal disturbance
• LCD segment display with intuitive menu navigation, supporting parameter recall, error logging, and manual override modes

Sample Compatibility & Compliance

The DHZ-CA accommodates standard laboratory vessels including Erlenmeyer flasks (up to 3000 mL × 8), culture bottles (1000 mL × 24), or test tubes/bottles (250 mL × 60) using its universal spring clamp fixture. Its chamber dimensions (1190 × 720 × 440 mm W×D×H) provide ample headroom for stacked configurations and permit integration with external gas supply lines (e.g., CO₂ or O₂ enrichment) via optional port adapters. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets GB/T 28026.1–2011 (Chinese national standard for incubator shakers). While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its operational logs, parameter traceability, and hardware-level timer redundancy support GLP/GMP-aligned documentation workflows when paired with validated SOPs.

Software & Data Management

This model operates via embedded firmware without external PC dependency; however, it supports RS-232 serial interface (optional) for integration into centralized lab monitoring systems. All active parameters—including setpoints, elapsed time, current temperature, and RPM—are retained in non-volatile memory during power interruption. Event-based logging captures startup, shutdown, over-temperature alerts, and timer completion signals. For regulatory environments, users may implement third-party data acquisition software (e.g., LabVIEW or custom Python scripts) to record timestamps, generate CSV reports, and enforce audit trails meeting ALCOA+ principles. Firmware updates are performed via USB interface with version-locking safeguards to preserve validation integrity.

Applications

• Microbial and mammalian cell culture expansion under controlled aeration and thermal conditions
• Enzyme kinetics assays requiring homogeneous suspension and precise incubation timing
• Biochemical reaction optimization, including protein expression, plasmid propagation, and metabolic pathway studies
• Environmental microbiology: soil suspension homogenization, water quality BOD/COD preparation, and bioremediation simulation
• Vaccine and diagnostic reagent development where batch-to-batch consistency depends on reproducible agitation profiles
• Plant tissue culture and callus induction protocols demanding gentle orbital motion and narrow thermal variance

FAQ

Is the DHZ-CA suitable for use with volatile organic solvents?

Yes—the air-bath design avoids liquid contact and features sealed motor housings and non-sparking components compliant with Class I, Division 2 hazardous location guidelines when operated within specified ambient conditions.
Can the shaking platform be customized for specialized fixtures?

Standard platforms accept universal spring clamps; custom perforated plates, magnetic racks, or microplate holders can be fabricated per OEM specifications upon request.
Does the unit support remote monitoring or network connectivity?

Native Ethernet or Wi-Fi is not included, but RS-232/485 interfaces enable connection to SCADA systems or building management platforms via protocol converters.
What is the maximum load capacity of the platform?

Rated for 25 kg distributed load; dynamic imbalance must remain below 5% to maintain speed stability and bearing longevity.
How is calibration verified for temperature and speed?

Factory calibration includes NIST-traceable RTD verification at three points (30°C, 45°C, 60°C) and tachometric RPM validation; users may perform field checks using Class A platinum resistance thermometers and optical tachometers.
