CZGY THZ-D Benchtop Incubator Shaker

Overview

The CZGY THZ-D Benchtop Incubator Shaker is an engineered platform for precise temperature-controlled orbital agitation of biological and chemical samples in research and quality control laboratories. Based on the principle of controlled orbital motion—where a circular drive mechanism imparts uniform, low-shear oscillation to sample containers—the instrument ensures consistent mixing, suspension, and aeration critical for microbial growth, cell culture expansion, enzyme kinetics, and biochemical assay development. Its air-bath heating architecture delivers rapid thermal equilibration and stable setpoint maintenance across the full operating range (ambient +5°C to 60°C), with digital PID regulation ensuring ±0.5°C temperature accuracy. Designed for daily benchtop use in academic, clinical, pharmaceutical, and environmental testing labs, the THZ-D integrates mechanical robustness, operational simplicity, and regulatory-ready functionality without compromising on reproducibility or long-term reliability.

Key Features

• Brushless DC motor drive for silent, maintenance-free operation and extended service life with minimal speed drift over time
• Mirror-finish 304 stainless steel chamber interior resistant to corrosion, cleaning agents, and repeated sterilization cycles
• Powder-coated cold-rolled steel housing providing structural rigidity and resistance to abrasion and chemical splashes
• Integrated LDC (Liquid Crystal Display) control panel with real-time digital readouts for temperature, speed, and remaining timer duration
• Orbital motion profile (26 mm diameter) optimized for uniform suspension of cells, bacteria, and particulates—configurable to reciprocating motion per user specification
• Wide speed range (40–300 rpm) with fine-resolution adjustment and stable speed retention under load variation
• Extended programmable timer (0–9999 minutes or hours) supporting unattended overnight and multi-day incubation protocols
• Standard 440 × 350 mm platform fitted with adjustable stainless steel spring clamps accommodating flasks (50–2000 mL), test tubes, and deep-well plates

Sample Compatibility & Compliance

The THZ-D accommodates a broad spectrum of sample formats including Erlenmeyer flasks, baffled flasks, centrifuge tubes, Petri dishes, and microtiter plates—enabling applications from aerobic bacterial cultivation to recombinant protein expression. Its temperature uniformity profile (±0.8°C across platform surface, measured per ASTM E2500-18 guidelines) supports GLP-compliant method validation. While not certified to ISO/IEC 17025 out-of-the-box, the unit’s traceable temperature and speed calibration points allow integration into laboratory quality systems aligned with ISO 13485 (medical device QA), USP (analytical instrument qualification), and FDA 21 CFR Part 11–compliant data workflows when paired with validated external logging software.

Software & Data Management

The THZ-D operates as a standalone instrument with no embedded software stack; all parameters are set and monitored via its front-panel LDC interface. For laboratories requiring audit trails and electronic records, optional RS-232 or USB-to-serial adapters enable connection to third-party data acquisition platforms (e.g., LabVIEW, MATLAB, or custom Python-based logging tools). Timestamped temperature and speed logs can be exported for inclusion in SOP documentation, equipment qualification reports (IQ/OQ/PQ), and regulatory submissions. Firmware updates are performed manually via manufacturer-provided utility—no cloud dependency or automatic remote access is implemented, preserving network security and data sovereignty.

Applications

• Microbial culture propagation (E. coli, yeast, Bacillus spp.) under controlled aeration and thermal conditions
• Cell line maintenance and passaging in suspension-adapted mammalian or insect cultures
• Biochemical reaction optimization—including ligand binding assays, antigen-antibody incubations, and ELISA plate shaking steps
• Environmental sample processing: extraction of heavy metals from soil leachates, microbial degradation studies in wastewater matrices
• Pharmaceutical stability testing: dissolution enhancement trials, excipient compatibility screening under agitated thermal stress
• Teaching laboratories: hands-on instruction in fermentation kinetics, growth curve analysis, and sterile technique under variable agitation regimes

FAQ

What is the maximum flask size supported on the standard platform?
The 440 × 350 mm platform accommodates up to two 2 L Erlenmeyer flasks or four 1 L flasks using the included stainless steel spring clamps.
Can the THZ-D operate at temperatures below ambient?
No—the THZ-D is a heating-only air-bath shaker. For sub-ambient capability, refer to the THZ-DL full-temperature variant (5–60°C), which incorporates a thermoelectric cooling module.
Is speed calibration traceable to NIST standards?
Yes—each unit undergoes factory calibration using a NIST-traceable tachometer; calibration certificates are available upon request for GxP environments.
Does the unit meet electrical safety requirements for international use?
The THZ-D complies with GB 4793.1–2019 (Chinese equivalent of IEC 61010-1) for laboratory electrical equipment. For CE or UL listing, contact CZGY for region-specific variants with modified power input modules.
Can I retrofit a humidity control module?
No—humidity regulation is not supported due to the open-air bath design. For humidified incubation with agitation, consider CZGY’s dedicated CO₂ incubator shakers or stacked incubator-shaker configurations.
