Overview
The ZHWY ZWY-1112B Dual-Layer High-Capacity Incubated Orbital Shaker is an engineered solution for laboratories requiring precise, reproducible, and scalable temperature-controlled agitation across large-volume culture formats. Designed around a robust vertical dual-shelf architecture, it delivers orbital motion (circular oscillation) with a fixed 35 mm diameter orbit—optimized for homogeneous suspension of microbial, mammalian, and hybridoma cultures while minimizing shear stress on sensitive cells. Its forced convection airflow system ensures rapid thermal equilibration and uniform chamber conditions (≤ ±1.0 °C at 37 °C), critical for applications such as aerobic fermentation, recombinant protein expression, and bioprocess development. The unit operates within a controlled ambient environment (5–25 °C) and maintains setpoint accuracy to ±0.1 °C using a PID microprocessor controller with environmental scanning compensation—ensuring stability even during door openings or ambient fluctuations. With a total internal volume of 582 L and dual 970 × 560 mm stainless-steel shelves, the ZWY-1112B supports high-density vessel configurations up to 1000 mL × 36 per shelf, making it suitable for pilot-scale cultivation, QC batch testing, and GMP-aligned upstream processing workflows.
Key Features
- Vertical dual-layer design minimizes laboratory floor footprint while maximizing volumetric capacity—ideal for space-constrained cleanrooms and biosafety suites.
- PID-based microprocessor controller with real-time environmental scanning continuously adjusts heating output to counteract thermal drift from external load changes or ambient variation.
- Backlit LCD interface displays simultaneous readouts of setpoint and actual values for temperature, speed, and remaining time—enabling immediate verification without menu navigation.
- Parameter lock function prevents unauthorized modification of operational settings; password protection ensures compliance with SOP-driven environments.
- Soft-start acceleration circuitry gradually ramps motor speed to target rpm, eliminating sudden torque surges that may dislodge vessels or disrupt fragile cell aggregates.
- Comprehensive safety suite includes over-temperature cutoff, motor overheat detection, independent power interruption recovery, and audible/visual alarms for fault conditions.
- Electrostatically coated steel cabinet with tempered glass double-door access enables unobstructed visual monitoring without compromising thermal integrity.
- Brushless AC induction motor provides maintenance-free operation, consistent torque delivery across full speed range (30–300 rpm), and extended service life under continuous duty cycles.
Sample Compatibility & Compliance
The ZWY-1112B accommodates standard microbiological and biopharmaceutical vessel formats—including Erlenmeyer flasks (100–1000 mL), baffled bottles, roller bottles, and multi-well plates mounted on custom platforms. Its orbital motion profile meets ASTM D4064-20 (Standard Practice for Agitation of Liquid Cultures) and aligns with ISO 21528-2:2017 requirements for incubator shaker performance validation. For regulated environments, the device supports audit-ready documentation through optional data logging interfaces (RS-232/USB), enabling traceable records compliant with FDA 21 CFR Part 11 when integrated with validated software systems. Temperature uniformity and stability data are generated per ISO/IEC 17025-accredited calibration protocols, supporting GLP and GMP process qualification activities in pharmaceutical manufacturing and clinical diagnostics labs.
Software & Data Management
While the ZWY-1112B operates autonomously via its embedded controller, it features serial communication ports (RS-232 and USB) for integration with third-party laboratory information management systems (LIMS) or SCADA platforms. Optional firmware upgrades enable time-stamped event logging—including door open/close events, temperature excursions, speed deviations, and alarm triggers—with exportable CSV files for trend analysis and regulatory submission. When deployed alongside validated PC-based control software (sold separately), users gain remote monitoring, multi-unit synchronization, electronic signature capability, and automated report generation aligned with ALCOA+ data integrity principles.
Applications
- Microbial fermentation and seed train expansion in biopharmaceutical upstream processing
- High-yield expression of therapeutic proteins in E. coli, yeast, and insect cell lines
- Stability studies under controlled temperature and agitation for formulation development
- Cell culture maintenance and passaging in academic and industrial research labs
- Environmental microbiology assays requiring standardized oxygen transfer rates
- Enzyme kinetics profiling where consistent mixing velocity is essential for reaction homogeneity
- Quality control testing of raw materials and intermediates in food, cosmetic, and nutraceutical production
FAQ
What is the recommended ambient operating environment for the ZWY-1112B?
The unit must be installed in a climate-controlled room maintained between 5–25 °C with adequate ventilation and minimal direct sunlight exposure.
Can this shaker be used for refrigerated applications?
No—the ZWY-1112B is a heating-only incubated shaker with a minimum temperature setpoint of ambient +5 °C; it does not include active cooling capability.
Is the shaking platform compatible with magnetic stir bars or orbital plate adapters?
The standard platform supports flask clamps and universal rubber mats; custom mounting kits for microplate carriers or specialized fixtures are available upon request.
Does the device meet electromagnetic compatibility (EMC) standards for use in hospital or clinical lab settings?
Yes—it complies with IEC 61326-1:2013 for laboratory equipment EMC and carries CE marking for conformity with EU directives.
How is temperature uniformity verified during factory calibration?
Nine-point thermocouple mapping is performed at 37 °C using NIST-traceable sensors; final uniformity certification (≤ ±1.0 °C) is included in the delivery documentation.
