Zhicheng ZWY-1102 Dual-Layer High-Capacity Incubated Orbital Shaker

Overview

The Zhicheng ZWY-1102 Dual-Layer High-Capacity Incubated Orbital Shaker is an engineered solution for laboratories requiring precise, reproducible, and scalable temperature-controlled agitation across diverse life science applications. Designed around a robust vertical dual-chamber architecture, it integrates orbital shaking mechanics—based on controlled eccentric rotation—with forced-air convection heating to maintain uniform thermal conditions throughout its 332 L internal volume. Unlike benchtop or single-layer units, the ZWY-1102 employs a multi-dimensional drive system that ensures mechanical stability at high speeds (up to 300 rpm) while minimizing harmonic resonance and sample disturbance. Its operational envelope—spanning 30–300 rpm and +5°C to 60°C above ambient—is optimized for bacterial growth, yeast fermentation, hybridization kinetics, enzyme assays, and suspension cell culture protocols where both thermal fidelity and oscillatory consistency are critical. The unit operates without active refrigeration, making it suitable for ambient-cooled environments within ISO Class 7 or better laboratory spaces.

Key Features

• PID-controlled microprocessor with environmental scanning logic ensures dynamic compensation for load variation, door opening events, and ambient drift—delivering ≤±0.1°C temperature stability at 37°C.
• Dual independent shelves (734 × 458 mm each), each supporting up to 104 × 50 mL flasks or 24 × 1000 mL bottles, enable parallel processing of heterogeneous sample sets under identical conditions.
• Backlit LCD interface displays real-time values for temperature, speed, elapsed time, and remaining timer duration—alongside user-defined setpoints—supporting GLP-compliant documentation practices.
• Programmable timer (0–500 h) triggers audible and visual alerts upon completion and automatically cuts power to the motor and heater, preventing over-incubation or thermal runaway.
• Brushless AC induction motor delivers constant torque across the full speed range, eliminating carbon wear and reducing long-term maintenance intervals.
• Comprehensive safety architecture includes over-temperature cutoff (with independent thermal fuse), motor overheat protection, and auto-restart after power interruption—retaining all prior settings per IEC 61000-4-11 compliance.
• Electrostatically coated steel enclosure with tempered glass double-door viewport supports ergonomic monitoring without compromising thermal integrity or containment.

Sample Compatibility & Compliance

The ZWY-1102 accommodates standard microbiological and bioprocessing vessels—including Erlenmeyer flasks (50–1000 mL), Fernbach flasks, baffled bottles, and custom bioreactor bags—across two independently accessible tiers. Its Φ26 mm orbit diameter and low-vibration drive train minimize shear stress on sensitive mammalian or insect cell suspensions. The unit meets structural requirements for ISO 13485-aligned equipment qualification and supports IQ/OQ protocols under GMP-regulated environments. While not intrinsically compliant with FDA 21 CFR Part 11, its parameter-locking function, non-volatile memory retention, and audit-ready display logging facilitate alignment with ALCOA+ data integrity principles when integrated into validated workflows.

Software & Data Management

The ZWY-1102 operates as a standalone instrument with embedded firmware—no external PC or proprietary software required. All operational parameters are stored in non-volatile memory and persist through power cycles. For laboratories implementing centralized monitoring, optional RS-485 or analog 4–20 mA output modules (sold separately) allow integration with SCADA systems or building management platforms. Time-stamped event logs—including door openings, temperature excursions >±0.5°C, and speed deviations >±2 rpm—can be manually reviewed via the LCD interface and exported using third-party serial capture tools compatible with Modbus RTU protocol.

Applications

This shaker serves core functions in academic research labs, CROs, and pharmaceutical manufacturing sites. It is routinely deployed in: aerobic microbial cultivation (e.g., E. coli, Bacillus subtilis) for plasmid amplification and protein expression; aerobic yeast propagation for vaccine adjuvant production; hybridization buffer equilibration in nucleic acid probe development; enzymatic reaction optimization under kinetic control; and pre-fermentation seed train expansion in API synthesis. Its dual-shelf configuration also supports comparative studies—such as media formulation screening or strain performance benchmarking—where replicate conditions must be maintained across multiple vessel types simultaneously.

FAQ

Does the ZWY-1102 include active cooling capability?
No. It features only programmable heating and forced-air convection. Ambient temperature must remain between 5°C and 25°C for stable operation within the specified +5°C to 60°C range.
Can the two shelves operate at different temperatures or speeds?
No. Both shelves share a common thermal chamber and drive system; temperature and oscillation parameters are uniform across the entire cavity.
Is calibration documentation provided with shipment?
Factory calibration certificates for temperature and speed sensors are available upon request and may be included in the delivery package for regulated users.
What maintenance is required beyond routine cleaning?
Annual verification of PID loop response, door seal integrity, and fan airflow rate is recommended. No lubrication or motor servicing is required due to the brushless design.
How is traceability ensured for GLP/GMP audits?
All user-modifiable parameters are password-locked, and the display retains last-set values even after power loss—enabling reconstruction of experimental conditions during audit review.
