ZWY-3723B Triple-Layer Large-Capacity Orbital Shaker

Overview

The ZWY-3723B Triple-Layer Large-Capacity Orbital Shaker is an industrial-grade, open-platform incubation shaker engineered for high-throughput microbial cultivation, fermentation, and biochemical reaction monitoring under controlled ambient conditions. Designed for integration into centralized temperature-controlled rooms—such as cleanroom-aligned bioproduction suites or GMP-compliant pilot-scale labs—the unit operates on the principle of orbital (circular) motion, generating uniform shear forces across culture vessels via a precisely balanced eccentric drive mechanism. Unlike enclosed incubator shakers, the ZWY-3723B relies on natural convection for thermal exchange, making it ideal for applications where rapid heat dissipation, mechanical accessibility, and scalability are prioritized over precise internal chamber humidity or CO₂ control. Its triple-layer configuration supports six independently accessible shelves, each accommodating up to twelve 2 L Erlenmeyer flasks (or equivalent vessel configurations), enabling parallel processing of >70 L total working volume per run.

Key Features

• PID-based microprocessor controller with real-time environmental scanning ensures stable speed regulation and minimizes thermal drift during extended operation (up to 500 h continuous runtime).
• Backlit LCD interface displays setpoints and real-time values for speed, elapsed time, and system status—supporting multilingual menu navigation (English default) and intuitive parameter entry via membrane keypad.
• Parameter encryption lock prevents unauthorized modification of critical operational settings, satisfying internal SOP enforcement and audit-readiness requirements in regulated environments.
• Soft-start acceleration circuitry gradually ramps motor torque to target rpm, eliminating abrupt jolts that may compromise cell viability or cause media splashing in sensitive suspension cultures.
• Maintenance-free AC induction motor delivers consistent torque across the full 30–180 rpm range, with no carbon brushes, commutators, or scheduled lubrication intervals—reducing long-term TCO and downtime risk.
• Auto-recovery function restores pre-interruption settings—including speed, timer, and shelf activation state—following transient power loss, ensuring experimental continuity without manual reconfiguration.
• Structural integrity is ensured by cast iron base plates and die-cast aluminum shelf frames, CNC-machined to ≤±0.05 mm flatness tolerance, minimizing vibration transmission and enhancing long-term mechanical stability.

Sample Compatibility & Compliance

The ZWY-3723B accommodates standard microbiological and bioprocess vessels—including glass and PETG Erlenmeyer flasks (50 mL to 2 L), baffled shake flasks, multi-well plates (with adapter trays), and custom bioreactor sleeves—across all six shelves. Each shelf features non-slip silicone matting and adjustable retaining clips to secure heterogeneous load configurations. While not certified as a Class II biological safety device, the open architecture complies with ISO 13485 design controls for ancillary lab equipment and meets IEC 61010-1:2010 safety standards for laboratory electrical apparatus. For GLP/GMP workflows, the unit supports 21 CFR Part 11-compliant data logging when interfaced with validated third-party acquisition software (e.g., LabArchives or DeltaTrak Validator Suite) via RS-232 or optional USB-to-serial bridge.

Software & Data Management

The embedded controller logs timestamped operational events—including start/stop cycles, alarm triggers (over-speed, timeout, thermal fault), and parameter changes—to internal flash memory (retains ≥10,000 entries). Export is supported via USB port using FAT32-formatted drives; exported .csv files include columns for datetime, shelf ID, set rpm, actual rpm (averaged over 5-s intervals), and error codes. Optional PC software (ZWY-Link v3.2, Windows 10/11 compatible) enables remote monitoring, batch protocol scheduling, and PDF report generation with digital signature fields—facilitating adherence to ALCOA+ data integrity principles. Audit trail functionality records user ID, action type, and timestamp for every configuration change, aligning with FDA and EMA expectations for instrument qualification documentation.

Applications

This shaker serves core functions in upstream bioprocess development, including aerobic bacterial and yeast strain propagation (e.g., E. coli, S. cerevisiae), recombinant protein expression screening, plasmid amplification, and enzyme kinetics assays. It is routinely deployed in QC microbiology labs for USP / compendial testing, environmental monitoring media preparation, and antimicrobial efficacy studies. In academic and translational research, it supports tissue dissociation protocols, hybridoma expansion, and synthetic biology chassis optimization—particularly where scalability from benchtop (ZWY-B311) to pilot scale (ZWY-3723B) is required. Its natural convection design also makes it suitable for non-sterile applications such as buffer mixing, solubility testing, and particulate suspension homogenization in pharmaceutical formulation labs.

FAQ

Is the ZWY-3723B suitable for use inside a temperature-controlled incubation room?
Yes—it is explicitly designed for installation in shared ambient-temperature rooms (5–50 °C) with external HVAC support, not as a self-contained incubator.
Can individual shelves be operated independently?
No—shelves operate synchronously at the same rpm and timing profile; independent control requires separate single-shelf units.
What is the maximum flask size supported per shelf?
Each 780 × 620 mm shelf holds up to twelve 2 L flasks with standard neck spacing; larger vessels require custom fixture validation.
Does the unit include validation documentation (IQ/OQ/PQ)?
Factory-issued IQ/OQ templates are provided; PQ must be executed onsite per user-defined protocols and regulatory jurisdiction.
Is CE or UL certification available?
The unit carries CCC (China Compulsory Certification); CE marking requires additional EMC testing per EN 61326-1, available upon request for EU-bound shipments.
