Overview
The Taicang Jiangsu THZ-D Air-Bath Constant-Temperature Orbital Shaker is an engineered platform for precise temperature-controlled agitation of biological and chemical samples in laboratory environments. Designed around a robust air-bath heating system and orbital motion principle—where sample containers rotate along a horizontal circular path with a fixed 26 mm orbit diameter—the instrument ensures uniform heat distribution and consistent mixing without mechanical shear stress associated with reciprocating or rotary shaking. Its operating temperature range spans from ambient +3°C to 60°C, making it suitable for bacterial culture propagation, enzyme kinetics studies, solubility testing, and general incubation-agitation workflows. The unit employs PID-based digital temperature regulation with high thermal stability (±0.3°C typical), while the brushless DC motor delivers smooth, low-vibration oscillation across the full 50–300 rpm frequency range. Constructed with a reinforced steel chassis and powder-coated enclosure, the THZ-D meets structural durability requirements for continuous operation in QC labs, academic research facilities, and bioprocessing support areas.
Key Features
- Orbital shaking mechanism with 26 mm orbit diameter ensures gentle yet effective suspension of microbial cultures, cell suspensions, and reagent solutions.
- Digital LED display with intuitive keypad interface for independent real-time monitoring and adjustment of temperature setpoint and oscillation speed.
- Precise PID temperature control delivering ±0.3°C stability at 37°C (typical), validated per ISO/IEC 17025-compliant calibration protocols.
- Programmable timer (0–999 minutes) with auto-shutdown function supports unattended overnight experiments and standardized SOP execution.
- Universal clamp system accommodates a wide variety of vessel formats—including Erlenmeyer flasks (250 mL × 15 or 1000 mL × 6), test tubes, and custom labware—without requiring accessory swaps.
- Compliance-ready design: CE-marked, RoHS-conformant, and compatible with GLP/GMP documentation workflows via manual logbook integration.
Sample Compatibility & Compliance
The THZ-D supports standard microbiological and biochemical sample vessels up to 1000 mL volume, including borosilicate glass and polypropylene flasks rated for sustained operation at ≤60°C. Its air-bath architecture eliminates direct contact between heating elements and samples—reducing condensation risk and enabling stable humidity management during extended incubation. While not a regulated medical device, the shaker conforms to IEC 61010-1 safety standards for laboratory equipment and includes overtemperature cut-off protection. For regulated environments, users may implement procedural controls (e.g., daily temperature verification using NIST-traceable thermometers) to align with FDA 21 CFR Part 11 data integrity expectations when paired with external electronic lab notebooks.
Software & Data Management
The THZ-D operates as a standalone hardware platform with no embedded software or network connectivity. All operational parameters are configured manually via front-panel controls, and no data logging or remote interface is provided. This architecture simplifies validation, reduces cybersecurity exposure, and facilitates straightforward IQ/OQ protocol development. Users seeking automated data capture may integrate the unit with third-party environmental monitoring systems via analog output modules (optional add-on) or employ time-synchronized external thermocouple loggers compliant with ASTM E2874 for thermal profile recording.
Applications
- Bacterial and yeast culture expansion under controlled aerobic conditions (e.g., E. coli, S. cerevisiae)
- Protein solubilization and buffer equilibration prior to chromatography or electrophoresis
- Chemical reaction kinetics where temperature-dependent mixing efficiency must be maintained
- Environmental sample homogenization (e.g., soil extracts, water microbiology preparations)
- Pharmaceutical excipient dispersion testing in pre-formulation development
- Teaching laboratories requiring reproducible, entry-level incubation-shaking capability
FAQ
Is the THZ-D suitable for use with volatile organic solvents?
Yes—its air-bath design avoids open flame or exposed heating coils; however, users must verify flask cap integrity and ensure adequate ventilation per OSHA 1910.1200 guidelines.
Does the unit include a refrigeration system?
No—the THZ-D is a heating-only air-bath shaker. For sub-ambient applications, consider the DHZ-D or LSHZ-300 series models.
Can the oscillation speed be calibrated?
Speed calibration is performed at factory level using optical tachometry; field recalibration is not supported but periodic verification with a handheld digital tachometer is recommended per internal QA procedures.
What maintenance is required?
Routine cleaning of the chamber interior and platform surface with 70% ethanol; annual inspection of motor coupling and fan filter (if equipped); no lubrication required due to brushless motor construction.
Is the universal clamp compatible with microtiter plates?
Not natively—the clamp system is optimized for conical flasks and cylindrical vessels; plate adapters are available as optional accessories (model UCA-PLATE).
