Qiangle THZ-D Benchtop Air-Incubated Orbital Shaker

Overview

The Qiangle THZ-D Benchtop Air-Incubated Orbital Shaker is an engineered solution for precise, reproducible incubation and mixing of biological and biochemical samples under controlled temperature and orbital agitation conditions. Designed for laboratories requiring consistent aeration, suspension, and thermal uniformity in microbiological cultures, cell line propagation, enzyme assays, and solubility studies, the THZ-D employs a robust air-jacketed heating system—distinct from water- or oil-bath alternatives—to maintain stable chamber temperatures without direct liquid contact. Its orbital motion (26 mm amplitude) ensures gentle yet effective homogenization across diverse vessel types, minimizing shear stress on sensitive cells while maximizing oxygen transfer efficiency. The device operates within a calibrated temperature range of ambient +3°C to 60°C, with microprocessor-based PID control enabling ±0.5°C thermal accuracy across the working volume. As a benchtop platform, it integrates seamlessly into standard biosafety cabinets, clean benches, and modular lab workflows—supporting GLP-compliant documentation when paired with external logging systems.

Key Features

• Microprocessor-controlled PID temperature regulation with real-time LED display for simultaneous monitoring of setpoint and actual chamber temperature
• Adjustable orbital speed (50–300 rpm) with digital speed calibration and low-speed stability (<5 rpm deviation at setpoint)
• Air-incubated design eliminates condensation risk and simplifies maintenance versus liquid-bath shakers; no fluid refills, leaks, or corrosion concerns
• Stainless-steel platform with reinforced universal clamping system accommodating round-bottom flasks, Erlenmeyer vessels, test tubes, and multi-well plates (with optional adapters)
• Thermal insulation and airflow optimization ensure uniform temperature distribution (±0.8°C across platform surface per ASTM E2500-19 validation guidelines)
• Over-temperature and motor overload protection circuits compliant with IEC 61010-1 safety standards
• Compact footprint (680 × 500 × 480 mm) optimized for space-constrained environments including BSL-2 labs and teaching facilities

Sample Compatibility & Compliance

The THZ-D accommodates standard laboratory glassware and plastic vessels up to 1000 mL capacity—including 250 mL flasks (15 positions) or 1000 mL bottles (6 positions)—without requiring custom trays. Its universal clamp system supports variable neck diameters (12–50 mm) and permits rapid reconfiguration between culture formats. The unit meets key regulatory expectations for routine QC/QA applications: temperature control performance aligns with ISO/IEC 17025 requirements for equipment qualification; its electrical architecture conforms to CE marking directives (2014/30/EU EMC and 2014/35/EU LVD); and operational parameters are traceable via factory calibration certificates (NIST-traceable reference thermistors). While not inherently 21 CFR Part 11–compliant, the THZ-D supports audit-ready workflows when integrated with validated third-party data loggers for electronic record retention.

Software & Data Management

The THZ-D operates via embedded firmware with no proprietary software dependency—ensuring long-term usability without license renewal or OS compatibility constraints. All operational parameters (temperature setpoint, speed, runtime) are stored in non-volatile memory and retained after power interruption. For enhanced traceability, users may connect external USB or RS-232 data loggers to capture time-stamped temperature and RPM profiles. The LED interface provides immediate visual feedback: dual-line display shows target vs. measured values, while status icons indicate heating active, speed stabilizing, or fault conditions (e.g., sensor open-circuit). Firmware updates—distributed annually via secure FTP—are field-installable using standard serial terminal emulation tools, supporting continuous compliance with evolving laboratory informatics standards.

Applications

This shaker serves core functions across academic, pharmaceutical, and industrial life science settings: microbial growth kinetics (E. coli, yeast, bacilli), mammalian cell suspension culture (CHO, HEK293), antibiotic susceptibility testing (AST), protein expression in autoinduction media, biodegradation assays, and environmental sample enrichment (e.g., wastewater microbiota). Its air-heated chamber avoids cross-contamination risks associated with shared water baths and enables rapid thermal equilibration (≤15 min from ambient to 37°C). Researchers routinely deploy the THZ-D in method development for USP microbial enumeration, ISO 11731 Legionella cultivation, and CLSI M07-A1 broth dilution protocols—where consistent agitation and thermal fidelity directly impact colony-forming unit (CFU) reproducibility.

FAQ

Is the THZ-D suitable for CO₂-sensitive cultures?

No—this is a non-CO₂-capable air-incubated shaker. It maintains temperature and agitation only; users requiring pH stabilization via CO₂ must integrate it with external gas-regulated incubators or select dedicated CO₂ shaker models.

Can the universal clamp accommodate 50 mL conical tubes?

Yes—the clamp jaws adjust to grip tube diameters from 12 mm to 50 mm; optional silicone sleeves (sold separately) enhance grip for narrow-profile vessels.

What is the temperature uniformity specification across the platform?

Per internal validation per ASTM E2500-19 Annex A3, spatial uniformity is ±0.8°C at 37°C across the full load area (tested at 9 points using calibrated thermocouples).

Does the unit include a timer function?

Yes—a programmable countdown timer (0–99 h 59 min) with auto-shutdown and audible alert ensures unattended operation integrity.

Is calibration documentation provided with shipment?

Each unit ships with a Factory Calibration Certificate listing as-tested temperature accuracy (±0.4°C at 37°C) and speed deviation (±2 rpm at 200 rpm), traceable to national metrology institutes.
