Zhicheng ZWY-2112D Dual-Layer High-Capacity Large-Amplitude Temperature-Controlled Orbital Shaker

Overview

The Zhicheng ZWY-2112D is a dual-layer, high-capacity orbital shaker engineered for precision-controlled incubation and agitation across demanding life science and bioprocessing workflows. Designed around a robust forced-convection thermal architecture with PID microprocessor regulation, it maintains stable temperature uniformity (≤ ±1.0 °C at 37 °C) and exceptional stability (≤ ±0.1 °C at 37 °C) throughout its 4–60 °C operating range. Its orbital motion—generated via a multi-dimensional balanced drive system with a fixed 50 mm diameter orbit—ensures gentle yet effective suspension of microbial cultures, mammalian cells, and enzymatic reaction mixtures without shear-induced damage. The unit’s vertical dual-shelf configuration maximizes volumetric efficiency: two independently supported shelves (970 × 560 mm each), housed within a 582 L chamber, support up to 36 × 1000 mL flasks or 164 × 100 mL vessels—making it suitable for scale-up fermentation, seed train expansion, and GMP-aligned process development in pharmaceutical and biotech settings.

Key Features

• Dual-front access doors with tempered glass viewing windows enable rapid, non-intrusive monitoring while preserving chamber integrity and thermal consistency.
• PID-based environmental scanning controller with backlit LCD interface displays real-time and setpoint values for temperature, speed, and remaining time—supporting intuitive parameter navigation and secure data visibility.
• Programmable timer (0–500 h) with audible and visual end-point alarm ensures unattended operation compliance with GLP and SOP-driven protocols.
• Brushless AC induction motor delivers maintenance-free, constant-torque performance across the full 30–300 rpm range (±1 rpm accuracy), eliminating carbon wear and ensuring long-term rotational fidelity.
• Comprehensive safety architecture includes over-temperature cut-off, motor overheat protection, and automatic power resumption after transient grid failure—critical for continuity in regulated environments.
• Electrostatically coated steel enclosure and ergonomic streamline chassis provide structural rigidity, corrosion resistance, and compatibility with cleanroom-grade laboratory infrastructure.

Sample Compatibility & Compliance

The ZWY-2112D accommodates standard laboratory vessels—including Erlenmeyer flasks (100–1000 mL), culture bottles, and deep-well plates—across both shelves simultaneously. Its large orbit (Φ50 mm) and consistent acceleration profile minimize liquid splashing and foam formation during high-volume aerobic cultivation. The unit complies with IEC 61010-1 for electrical safety and meets essential requirements for use in ISO 13485-certified medical device manufacturing facilities. While not inherently 21 CFR Part 11 compliant, its parameter-locking function, audit-ready timer logs, and non-volatile memory support traceability when integrated into validated workflows under GMP or GLP quality systems.

Software & Data Management

This shaker operates as a standalone instrument with embedded firmware; no external software is required for basic operation. All user-defined parameters—including temperature setpoint, speed, and timer duration—are stored in non-volatile memory and retained during power cycling. The encrypted parameter lock prevents unauthorized modification, satisfying internal SOP controls. For laboratories requiring electronic record integration, optional RS-485 or analog 4–20 mA output modules (sold separately) enable connection to SCADA or LIMS platforms for remote status monitoring and periodic data logging—facilitating alignment with FDA-recommended data integrity principles (ALCOA+).

Applications

• High-yield microbial fermentation (e.g., E. coli, S. cerevisiae) in preclinical and pilot-scale bioreactor seed preparation.
• Long-duration enzyme kinetics assays requiring simultaneous temperature and agitation control.
• Hybridization and probe labeling steps in molecular diagnostics assay development.
• Cell line expansion and transfection optimization under controlled physiological temperatures (37 °C ±0.1 °C).
• Stability testing of biologics formulations under agitated, temperature-stressed conditions per ICH Q5C guidelines.
• Environmental microbiology studies involving soil or water sample enrichment under defined aerobic oscillation.

FAQ

Does the ZWY-2112D support refrigerated operation below ambient temperature?
No—it is a heating-only unit with a minimum setpoint of 4 °C. Cooling functionality requires external chilled water supply or integration with a separate refrigerated circulator.
Can both shelves operate at independent temperatures or speeds?
No—temperature and speed are uniformly applied across both shelves. The system is configured for homogeneous chamber-wide control.
Is calibration documentation included with shipment?
Factory calibration certificates for temperature and speed sensors are provided upon request; field recalibration services are available through authorized Zhicheng service partners.
What is the recommended maintenance schedule?
Beyond routine cleaning of interior surfaces and inspection of door gaskets, no scheduled mechanical maintenance is required due to the brushless motor design—only periodic verification of temperature uniformity and speed accuracy per ISO/IEC 17025 guidelines.
How does the unit handle voltage fluctuations common in industrial lab environments?
Integrated wide-range input circuitry (AC 220 V ±10%, 50/60 Hz) and an active power factor correction module ensure stable operation during minor grid deviations, minimizing thermal drift or speed variance.
