CZGY QHZ-98A Full-Temperature Orbital Shaking Incubator

Overview

The CZGY QHZ-98A Full-Temperature Orbital Shaking Incubator is an integrated laboratory instrument engineered for precise simultaneous control of temperature and orbital agitation—designed to support aerobic microbial growth, cell suspension culture, enzyme reaction kinetics, and biochemical solubilization under reproducible environmental conditions. Unlike static incubators, the QHZ-98A employs a robust orbital shaking mechanism based on a five-dimensional eccentric triple-cam drive system, ensuring stable motion across variable load distributions without requiring symmetrical placement of flasks or vessels. Its dual-zone microprocessor architecture independently regulates thermal and mechanical parameters via dedicated PID-controlled heating/cooling circuits and high-torque brushless AC induction motor control—enabling seamless transitions between low-temperature fermentation (4 °C) and high-yield mesophilic cultivation (up to 60 °C), while maintaining thermal stability within ±0.5 °C fluctuation and spatial uniformity within ±1 °C across the full 1000 × 640 mm platform.

Key Features

• Orbital shaking with 26 mm diameter motion—optimized for oxygen transfer in liquid cultures and compatible with standard Erlenmeyer flasks (250 mL × 54, 500 mL × 40, 1000 mL × 24, 2000 mL × 12, or 5000 mL × 6 configurations)
• Dual independent LCD interface displaying real-time setpoints and actual values for both temperature and rotational speed—eliminating ambiguity inherent in legacy LED-based systems
• PID temperature compensation algorithm minimizing overshoot and stabilizing chamber dynamics during ramp-up or setpoint changes
• High-capacity refrigeration unit utilizing environmentally compliant R134a refrigerant—engineered for low acoustic emission (<55 dB(A)) and consistent cooling performance down to 4 °C in ambient environments up to 30 °C
• Electrostatically powder-coated steel enclosure with reinforced tempered glass viewport and integrated LED illumination—facilitating non-invasive observation without thermal leakage
• Onboard UV-C sterilization lamp (254 nm) for periodic decontamination of interior surfaces—supporting GLP-compliant workflow hygiene protocols
• Programmable timer supporting duration settings from 1 minute to 9999 hours—enabling unattended overnight or multi-day experiments with automatic shutdown

Sample Compatibility & Compliance

The QHZ-98A accommodates heterogeneous vessel formats including glass and PET flasks, baffled bioreactor bottles, and multi-well plates (with optional adapter trays). Its load-tolerant drive architecture supports grossly asymmetric loading—e.g., partial filling of 24-position 1000 mL clamp arrays—without inducing mechanical resonance or platform wobble. The unit complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and meets electromagnetic compatibility requirements per EN 61326-1:2013. While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, its deterministic control logic, non-volatile parameter storage, and audit-ready timer logs enable traceable operation within GxP-aligned quality systems when paired with validated SOPs.

Software & Data Management

The QHZ-98A operates as a standalone instrument with no proprietary software dependency. All operational parameters—including setpoints, runtime, and alarm history—are retained in non-volatile memory through power cycles. Optional RS-485 serial interface (available upon request) permits integration into centralized lab monitoring networks using Modbus RTU protocol for remote readout of temperature, speed, and status flags. For regulated environments, users may implement external data loggers compliant with 21 CFR Part 11 requirements to capture time-stamped sensor outputs, satisfying ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate).

Applications

• Aerobic bacterial and yeast cultivation for bioprocess development and strain screening
• Suspension-based mammalian cell expansion in serum-free or chemically defined media
• Protein expression optimization in E. coli BL21(DE3) cultures under controlled aeration
• Enzymatic hydrolysis assays requiring constant mixing and narrow thermal windows
• Environmental microbiology studies involving soil slurry enrichment or wastewater biofilm dispersion
• Pharmaceutical excipient solubility testing across pharmacopeial temperature gradients (USP & EP)

FAQ

What is the maximum flask capacity supported on the platform?
The platform accommodates up to 54 × 250 mL flasks, 40 × 500 mL flasks, 24 × 1000 mL flasks, 12 × 2000 mL flasks, or 6 × 5000 mL flasks—depending on selected clamp configuration.
Does the unit support programmable ramp-and-soak temperature profiles?
No—the QHZ-98A provides single-setpoint temperature control only; multi-step thermal programming requires external controller integration.
Is the UV sterilization lamp interlocked with the door safety switch?
Yes—the UV lamp automatically deactivates when the front door is opened, complying with IEC 62471 photobiological safety requirements.
Can the incubator operate continuously at 4 °C in a 30 °C ambient room?
Yes—its high-efficiency compressor and insulated chamber design ensure stable sub-ambient operation under standard laboratory conditions.
Are calibration certificates available for temperature and speed verification?
Factory calibration reports are provided with each unit; NIST-traceable field calibration services can be arranged through authorized CZGY service partners.
