Overview
The ZWY-1112D Dual-Layer High-Capacity Large-Amplitude Temperature-Controlled Orbital Shaker is an engineered platform for scalable, reproducible incubation and agitation of biological samples under precisely regulated thermal and mechanical conditions. Designed for demanding applications in bioprocess development, fermentation optimization, and upstream biomanufacturing, this shaker employs orbital (circular) motion with a fixed 50 mm diameter amplitude—optimized to promote homogeneous oxygen transfer and suspension stability across high-volume cultures. Its dual-layer vertical architecture integrates two independently accessible, temperature-controlled decks within a compact footprint (1200 × 820 × 1600 mm), enabling parallel experiments or staggered batch processing without cross-contamination risk. The system utilizes PID-controlled forced-air convection heating and a robust AC induction motor with brushless operation, delivering stable rotational speeds from 30 to 300 rpm ±1 rpm across the full load range. Temperature control spans ambient +5°C to 60°C with resolution of ±0.1°C and uniformity ≤±1.0°C at 37°C—meeting critical requirements for mammalian cell culture, microbial growth kinetics, and enzyme activity assays.
Key Features
- Dual-layer vertical design with two independent 970 × 560 mm stainless-steel shaking platforms—total internal volume 582 L, maximum capacity up to 36 × 1000 mL flasks
- PID microprocessor-based environmental scanning controller with backlit LCD display showing real-time setpoints and measured values for temperature, speed, and time
- Programmable timer up to 500 hours with automatic shutdown and audible/visual alarm upon completion
- Intelligent security functions: parameter lockout to prevent unauthorized changes; power-failure recovery preserving all active settings and runtime
- Soft-start acceleration circuitry ensures smooth ramp-up to target speed—minimizing shear stress on sensitive cells or aggregated proteins
- Over-temperature protection with independent thermal cutoff; motor overheat detection; automatic power disconnection during fault conditions
- Electrostatically coated steel enclosure with reinforced tempered-glass double-door access and ergonomic handle design
Sample Compatibility & Compliance
The ZWY-1112D accommodates standard laboratory vessels—including Erlenmeyer flasks (100–1000 mL), baffled bottles, culture bags (with optional clamping fixtures), and multi-well plates mounted on custom adapters. Its uniform temperature distribution (≤±1.0°C at 37°C) and consistent orbital motion support GLP-compliant cultivation protocols per ISO 20387:2018 (biobanking) and USP (cell culture performance qualification). While not intrinsically certified for GMP manufacturing environments, the device’s traceable parameter logging, encrypted configuration locking, and audit-ready operational history align with FDA 21 CFR Part 11 data integrity expectations when integrated into validated workflows.
Software & Data Management
The embedded controller supports manual operation only—no external PC connectivity or proprietary software suite is included. All operational parameters (set temperature, speed, duration) are stored in non-volatile memory and retained after power cycling. Real-time values are continuously displayed on the 128 × 64 pixel LCD screen with backlighting for low-light lab environments. For laboratories requiring electronic records, third-party data loggers (e.g., Omega OM-DAQPRO-5300 series) may be interfaced via analog output ports (available upon request)—enabling CSV export, trend analysis, and integration into LIMS or ELN systems.
Applications
- High-density microbial fermentation (E. coli, yeast, Bacillus spp.) in R&D and pilot-scale bioreactor inoculum preparation
- Mammalian and insect cell suspension culture for recombinant protein expression and vaccine antigen production
- Enzyme kinetic studies requiring strict thermal and mixing consistency across replicate conditions
- Hybridization and nucleic acid amplification protocols where uniform agitation prevents pellet formation
- Environmental microbiology—BOD testing, biodegradation assays, and activated sludge acclimation
- Pharmaceutical QC: dissolution profile verification, excipient compatibility screening under agitated thermal stress
FAQ
What is the maximum flask loading capacity at 37°C with continuous operation?
At 37°C and 150 rpm, the unit supports sustained operation with up to 74 × 500 mL Erlenmeyer flasks (baffled) distributed evenly across both decks.
Does the shaker include refrigeration capability?
No—this model provides heating-only temperature control (ambient +5°C to 60°C); refrigerated variants (e.g., ZWY-1112DR) require separate specification.
Is calibration documentation provided with shipment?
Factory calibration certificates for temperature and speed sensors are available upon request prior to dispatch; user-performed periodic verification is recommended per ISO/IEC 17025 guidelines.
Can the unit operate safely in a controlled cleanroom environment?
The enclosure meets IP20 ingress protection rating; for ISO Class 7/8 cleanrooms, optional HEPA-filtered air intake kits and static-dissipative surface treatment must be specified at order stage.
What maintenance intervals are recommended for long-term reliability?
No scheduled motor servicing is required due to brushless AC induction design; annual inspection of door gaskets, fan filters, and leveling feet is advised per manufacturer’s maintenance log template.
