CZGY THZ-100B Benchtop Incubated Orbital Shaker

Overview

The CZGY THZ-100B Benchtop Incubated Orbital Shaker is an engineered platform for precise, reproducible cultivation of microbial, cellular, and biochemical samples under controlled temperature and agitation conditions. Utilizing air-jacketed thermal regulation and a brushless DC motor-driven orbital drive system, the instrument maintains uniform temperature distribution across the shaking surface while delivering stable rotational motion at user-defined frequencies. Its design adheres to fundamental principles of aerobic culture kinetics—ensuring optimal oxygen transfer through consistent orbital motion (26 mm diameter)—and supports standard microbiological growth protocols requiring incubation within the physiological range of 5°C above ambient to 60°C. The unit is intended for use in academic laboratories, pharmaceutical QC environments, clinical research facilities, and industrial bioprocessing development labs where ISO/IEC 17025-compliant equipment validation and GLP-aligned operational traceability are required.

Key Features

• High-stability orbital drive mechanism with brushless DC motor ensures long-term speed consistency and minimal mechanical drift (±1 rpm repeatability over 8-hour operation)
• Air-jacketed heating system with PID-controlled thermistor feedback enables rapid thermal equilibration and tight temperature regulation (±0.5°C accuracy at setpoint)
• Digital interface with dual LED displays for simultaneous real-time monitoring of speed (rpm) and chamber temperature (°C)
• Programmable timer supporting extended incubation cycles—from 1 minute to 9999 minutes (or hours), with auto-shutdown and alarm notification
• Single 440 × 350 mm stainless-steel tray with integrated spring-loaded clamps compatible with Erlenmeyer flasks (50–2000 mL), test tubes, and multi-well plates
• Robust enclosure: cold-rolled steel housing with corrosion-resistant epoxy finish; mirror-polished 304 stainless-steel inner chamber for easy cleaning and contamination control
• Standard built-in LED illumination facilitates visual sample inspection without opening the chamber door
• UV-free sterilization mode (via heated air circulation at ≥80°C for ≥30 min) supports routine decontamination between batches per laboratory biosafety guidelines

Sample Compatibility & Compliance

The THZ-100B accommodates common liquid-phase culture vessels used in molecular biology, fermentation studies, and enzyme kinetics assays—including baffled flasks, serum bottles, and sealed culture tubes. Its orbital motion profile complies with ASTM D5296-18 recommendations for mixing homogeneity in suspension cultures. The device meets IEC 61010-1:2010 safety standards for laboratory electrical equipment and is constructed to support routine cleaning validation per USP Analytical Instrument Qualification protocols. While not certified for GMP manufacturing environments, its operational logs (when paired with optional external data loggers) can be configured to satisfy FDA 21 CFR Part 11 requirements for audit trails in regulated research settings.

Software & Data Management

The THZ-100B operates as a standalone instrument with no embedded firmware-based data logging. However, analog output ports (0–5 V DC) are provided for integration with third-party SCADA systems or programmable logic controllers (PLCs). Users may connect external temperature and tachometric sensors to record time-stamped environmental parameters via compliant DAQ hardware (e.g., National Instruments USB-TC01 or Omega OM-DAQ-USB-2408). For laboratories implementing electronic lab notebooks (ELNs), CSV export from connected data acquisition software enables direct import into platforms such as LabArchives or Benchling—supporting ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate).

Applications

• Microbial growth curve analysis (E. coli, yeast, Bacillus spp.) under defined thermal and aeration conditions
• Protein expression optimization in liquid culture using autoinduction media
• Cell suspension maintenance for mammalian or insect cell lines during transient transfection workflows
• Biochemical assay preparation requiring homogeneous mixing prior to spectrophotometric or HPLC analysis
• Environmental sample enrichment (e.g., waterborne pathogen recovery per ISO 9308-1)
• Pre-analytical sample homogenization for downstream nucleic acid extraction or ELISA plate setup

FAQ

Can the THZ-100B operate continuously for 72+ hours without interruption?

Yes—the unit is rated for unattended operation up to 9999 minutes (≈166 hours) with thermal overload protection and automatic fan-cooling activation above 45°C.
Is the 26 mm orbit compatible with standard 2 L baffled flasks?

Yes—this orbit diameter provides sufficient shear and gas exchange for vessels up to 2 L when filled to ≤30% capacity, aligning with recommended working volumes in APHA Standard Methods 9222B.
Does the shaker support protocol recall or multi-step programs?

No—this is a single-setpoint instrument; programmable ramping or sequence-based profiles require external controller integration.
What calibration documentation is supplied with the unit?

A factory-issued temperature and speed verification report (traceable to NIST standards) is included; users must perform periodic in-house verification per ISO/IEC 17025 Clause 6.5.
Can the tray be replaced with a custom-sized platform?

Yes—CZGY offers OEM mechanical interfaces for user-designed trays; dimensional drawings and mounting specifications are available upon request.
