Overview
The Qiangle THZ-C-L Desktop Refrigerated Orbital Shaker is an engineered platform for precise, temperature-controlled agitation of biological and biochemical samples in research laboratories, quality control environments, and bioprocess development workflows. It operates on the principle of orbital shaking—generating a consistent circular motion with a fixed 26 mm orbit diameter—to ensure uniform suspension, aeration, and mixing across multi-well plates, flasks, and test tubes. Integrated refrigeration enables stable low-temperature operation down to 5 °C, making it suitable for applications requiring cold-sensitive enzyme activity preservation, microbial culture maintenance, or protein expression protocols where thermal drift must be minimized. The unit features a microprocessor-based intelligent temperature controller calibrated to deliver ±0.1 °C setpoint accuracy and ±0.5 °C chamber-wide uniformity—critical for reproducible kinetic assays and long-duration incubation studies.
Key Features
- Refrigerated orbital shaker with active cooling and heating capability, maintaining stable setpoints from 5 °C to 60 °C (at 25 °C ambient)
- Adjustable oscillation frequency range: 40–300 rpm, digitally controlled with real-time feedback for high repeatability
- Single large-format stainless-steel platform (standard configuration), optimized for load distribution and vibration damping
- Extended timer function: 0–999 minutes with auto-shutdown and audible alert
- Intelligent PID temperature controller with adaptive overshoot compensation—designed to mitigate regional environmental variations (e.g., high-humidity southern climates or low-ambient northern winters)
- Robust mechanical architecture: 56 kg mass, reinforced chassis, and precision-balanced drive system to minimize cross-axis vibration and acoustic noise
- 600 W power rating supports simultaneous temperature regulation and high-speed agitation without thermal throttling
Sample Compatibility & Compliance
The THZ-C-L accommodates standard laboratory vessels including Erlenmeyer flasks (up to 1000 mL × 6), culture tubes, deep-well microplates, and 250 mL bottles (up to 20 units per run). Its open-platform design allows rapid reconfiguration with optional clamps, adapters, and universal holders. While not certified for IEC 61000-6-3 EMC or ISO 13485 medical device manufacturing, the instrument meets general-purpose laboratory safety standards per GB 4793.1–2007 (equivalent to IEC 61010-1) for electrical safety and mechanical stability. It supports GLP-compliant documentation when used with external logging systems; however, it does not include built-in 21 CFR Part 11 audit trail functionality or electronic signature capability.
Software & Data Management
The THZ-C-L operates via an integrated front-panel interface with LED display and tactile membrane keys—no external software or PC connection required. All operational parameters (temperature setpoint, speed, timer duration) are stored in non-volatile memory and retained after power cycling. Real-time status indicators show current temperature, actual rpm, and remaining time. For laboratories requiring digital recordkeeping, users may integrate the unit into broader lab infrastructure using RS-232 or analog 0–10 V output (optional accessory module, sold separately) to feed data into LIMS or SCADA platforms. Firmware updates are performed manually via USB port (not included).
Applications
- Microbial growth studies under controlled hypothermic conditions (e.g., E. coli expression at 18 °C)
- Cell suspension culture in serum-free media requiring gentle, continuous agitation
- Enzyme kinetics assays where temperature stability directly impacts Vmax and Km determination
- DNA/RNA extraction protocols involving lysis buffer incubation and phase separation steps
- Antibiotic susceptibility testing using broth microdilution methods per CLSI M07-A11 guidelines
- Protein solubilization and refolding experiments requiring precise thermal ramping and orbital mixing
FAQ
Does the THZ-C-L support programmable ramping or multi-step temperature profiles?
No—the unit maintains a single user-defined temperature setpoint throughout operation. It does not offer gradient programming or sequential stage control.
Is the platform compatible with stackable multi-tier accessories?
No—only one standard platform is installed. Multi-layer configurations require third-party mounting hardware and are not validated by the manufacturer.
What is the minimum ambient temperature for reliable refrigeration performance?
The unit is rated for operation in ambient environments between 10 °C and 30 °C. Below 10 °C, compressor efficiency decreases and condensation risk increases; above 30 °C, cooling capacity degrades significantly.
Can the shaker be operated without temperature control (room-temperature-only mode)?
Yes—users may disable refrigeration/heating while retaining full speed and timer functionality.
Is calibration documentation provided with shipment?
A factory-issued temperature and speed verification report is included. NIST-traceable recalibration services are available through authorized service centers upon request.
