Overview
The DRETOP ZYC-400BH Air-Bath Orbital Shaker is an integrated laboratory instrument engineered for precise temperature-controlled orbital agitation of biological and biochemical samples. It operates on the principle of air-bath heating—where forced convection of heated ambient air ensures uniform thermal distribution across the oscillating platform—combined with smooth, low-shear orbital motion (26 mm diameter) optimized for suspension culture, microbial growth, enzyme kinetics, and cell-based assays. Unlike water-bath shakers, the air-bath design eliminates condensation risks, simplifies maintenance, and supports rapid temperature equilibration and stability (±0.1°C control accuracy). Its compact benchtop footprint and single-platform configuration make it especially suited for academic labs, QC environments, and pilot-scale bioprocessing workflows requiring reproducible, GLP-aligned incubation-shaking conditions.
Key Features
- Microprocessor-based P.I.D. temperature and speed control system with real-time digital display of setpoint and actual values for temperature (°C), rotational speed (rpm), and elapsed time (h)
- High-precision feedback regulation: temperature stability ±0.1°C; speed accuracy ±1 rpm; programmable alarm thresholds for over-temperature, overspeed, and timer expiration
- Brushless DC motor drive—maintenance-free, low-noise, constant-torque output across full speed range (0–300 rpm), with soft-start circuitry to prevent sample splashing during acceleration
- Three-dimensional eccentric cam drive mechanism ensuring smooth, balanced orbital motion and minimizing mechanical resonance or platform wobble
- Stainless steel chamber interior and platform surface; electrostatically coated steel outer casing; tempered glass viewing window with integrated LED illumination
- Configurable safety functions including parameter encryption, auto-restart after power interruption, temperature and speed calibration offsets, and dual-stage over-temperature cutoff
- Modular accessory support: universal spring clamps, fixed Erlenmeyer flask holders (50–5000 mL), test tube racks, and custom-fit bottle adapters
Sample Compatibility & Compliance
The ZYC-400BH accommodates standard microbiological and molecular biology vessels—including conical flasks (50 mL to 5000 mL), test tubes, deep-well plates, and serum bottles—on its 920 × 500 mm stainless steel platform. Optional features include oxygenation ports with manual shut-off valves for aerobic cultures and UV-C germicidal lamps (254 nm) for periodic decontamination of internal surfaces and recirculated air. The unit complies with IEC 61010-1:2010 for laboratory electrical safety and meets electromagnetic compatibility requirements per EN 61326-1. While not certified for GMP production environments out-of-the-box, its logging-capable controller and parameter-lock functionality support audit-ready operation under ISO/IEC 17025, CLIA, or FDA 21 CFR Part 11–aligned workflows when paired with validated SOPs.
Software & Data Management
Equipped with a USB interface, the ZYC-400BH enables direct data export of time-stamped temperature and speed profiles to PC-based analysis tools. Logged datasets include timestamp, setpoint, measured value, and alarm status—formatted as CSV for traceability and retrospective review. No proprietary software is required; exported files are compatible with Excel, MATLAB, and LabChart. The system retains up to 30 days of continuous operational history in non-volatile memory. For integration into centralized lab management systems, optional RS-485 Modbus RTU communication modules (sold separately) allow remote monitoring and control via SCADA or LIMS platforms.
Applications
This shaker serves core applications in life science research and quality control laboratories, including: bacterial and yeast cultivation under controlled aeration; protein expression in liquid media; hybridization kinetics for nucleic acid probes; solubility and dissolution testing of biopharmaceutical formulations; enzymatic reaction profiling; mammalian and insect cell suspension passaging; environmental microbiology (e.g., BOD incubation); and reagent mixing in diagnostic assay development. Its RT+5°C to 60°C operating envelope covers mesophilic growth conditions, enzyme assay temperatures, and accelerated stability studies—while avoiding thermal stress associated with higher-range incubators.
FAQ
What is the maximum load capacity of the platform?
The 920 × 500 mm platform supports up to 25 kg evenly distributed load, verified at 300 rpm without resonance or drift.
Can the ZYC-400BH be used for anaerobic cultures?
No—this model lacks gas-tight sealing or inert gas purging capability. For anaerobic work, consider supplemental glove box integration or dedicated anaerobic chambers.
Is calibration documentation provided with the instrument?
Factory calibration certificates for temperature and speed sensors are available upon request; users are responsible for periodic verification per ISO/IEC 17025 or internal QA protocols.
Does the unit support external temperature probes?
No—temperature sensing is internal only, using a high-stability Pt100 sensor embedded in the air stream near the platform.
What maintenance is required for long-term reliability?
Annual inspection of fan filter, motor mounting integrity, and door seal condition is recommended; no lubrication or belt replacement is needed due to brushless motor and cam-drive architecture.
