Overview
The Qiangle THZ-22(82) Benchtop Temperature-Controlled Orbital Shaker is an engineered solution for consistent, reproducible incubation and mixing of biological samples under controlled thermal conditions. Designed for routine laboratory workflows in microbiology, molecular biology, and cell culture applications, this shaker employs orbital motion—characterized by a circular horizontal displacement path—to ensure uniform suspension of cells, bacteria, or enzymatic reaction mixtures without shear-induced damage. Its integrated PTC heating element and PID-controlled temperature regulation deliver stable thermal environments from ambient +5°C up to 60°C, enabling applications ranging from bacterial growth optimization to enzyme kinetics assays. Unlike reciprocating or vortex shakers, the orbital design minimizes foaming and splashing while maximizing oxygen transfer efficiency—critical for aerobic microbial cultures in Erlenmeyer flasks.
Key Features
- Stepless speed control (40–300 rpm) with digital LED display and real-time feedback; maintained accuracy within ±5 rpm across the full range
- PID-based temperature regulation ensures thermal stability of ±0.5°C at setpoint (typical), with rapid equilibration and minimal overshoot
- Single-platform configuration optimized for standard 12-position 250 mL flask arrangement—compatible with common glass and polycarbonate vessels
- Robust steel frame construction with reinforced aluminum alloy platform and anti-slip silicone matting for secure sample retention
- Low-noise operation (≤50 dB[A] at 1 m, 240 rpm) suitable for shared lab environments and laminar flow hood integration
- Energy-efficient design: 250 W heating element paired with intelligent thermal cutoff and overtemperature protection circuitry
- No mechanical timer—designed for continuous operation or external programmable timer integration per GLP-compliant protocols
Sample Compatibility & Compliance
The THZ-22(82) accommodates standard conical flasks (up to 250 mL), test tubes, and shallow culture dishes on its 300 × 300 mm platform. Flask clamping is achieved via adjustable rubber grommets or optional universal clamp kits (sold separately). The unit complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and meets EMC requirements per EN 61326-1:2013. While not certified for Class II biological safety cabinets, its low electromagnetic emissions and compact footprint permit safe use adjacent to sensitive instrumentation. For regulated environments, the absence of built-in data logging necessitates external validation of temperature and speed performance per ISO/IEC 17025 or ASTM E2500 guidelines.
Software & Data Management
This shaker operates as a standalone analog-digital hybrid instrument with no embedded firmware, network interface, or proprietary software. All operational parameters—including speed and temperature—are set manually via front-panel rotary dials and confirmed by independent digital displays. This architecture eliminates cybersecurity risks and simplifies qualification (IQ/OQ/PQ) in GMP or GLP laboratories where audit trails must be generated externally. Users may integrate the device into broader lab automation systems using analog 0–10 V or 4–20 mA process signals (via optional analog I/O module) for remote monitoring of heater status or speed output. Calibration records and maintenance logs are maintained manually per internal SOPs.
Applications
- Bacterial and yeast culture expansion in nutrient broth (e.g., LB, YPD) at 30–37°C and 150–220 rpm
- Protein expression in E. coli BL21(DE3) strains requiring precise induction temperature control
- Suspension cell line maintenance (e.g., CHO, Sf9) in serum-free media under low-shear orbital agitation
- Enzyme activity assays requiring simultaneous thermal stabilization and homogeneous mixing
- Antibiotic susceptibility testing (AST) using broth microdilution methods per CLSI M07-A11
- Soil or water sample homogenization prior to microbial enumeration (ISO 11264:2022)
FAQ
Does the THZ-22(82) support programmable ramping or multi-step protocols?
No. It is a fixed-setpoint instrument with manual speed and temperature controls only.
Is the platform autoclavable or chemically resistant?
The aluminum platform is corrosion-resistant to common lab solvents (e.g., 70% ethanol, isopropanol) but is not autoclavable. Clean with non-abrasive disinfectants only.
Can it operate continuously for 72+ hours?
Yes. Rated for uninterrupted operation under nominal load; thermal protection prevents overheating during extended runs.
What calibration documentation is provided?
A factory calibration certificate for temperature and speed sensors is included, traceable to NIM (China National Institute of Metrology) standards.
Is there an option for CO₂ compatibility or humidity control?
No. This model lacks gas-tight enclosure or humidification capability; it is intended for ambient-air applications only.
