Zhicheng ZWYR-2112B Dual-Shelf Programmable Temperature-Controlled Orbital Shaker with Color Touchscreen

Overview

The Zhicheng ZWYR-2112B is a high-performance dual-shelf programmable orbital shaker engineered for precision-controlled incubation and agitation in life science laboratories. It integrates advanced thermal regulation, programmable motion sequencing, and robust safety architecture to support demanding applications including microbial cultivation, enzyme kinetics, cell suspension culture, and molecular hybridization. Its core operating principle relies on PID-controlled forced-air convection combined with a multi-dimensional balanced drive system that ensures uniform orbital motion (Φ35 mm) across both shelves—minimizing mechanical shear while maximizing oxygen transfer efficiency in liquid cultures. Designed for continuous operation under GLP-compliant workflows, the unit maintains temperature stability within ±0.1 °C at setpoint (e.g., 37 °C), with spatial uniformity ≤±1.0 °C across the full 582 L chamber volume—validated per ISO 20387 Annex B guidelines for biobanking equipment qualification.

Key Features

• Dual independent shelves (970 × 560 mm each) supporting simultaneous multi-condition experiments with identical or divergent protocols
• Full-color 7-inch capacitive touchscreen interface with animated Chinese-language GUI, enabling intuitive navigation through programming menus, real-time parameter visualization, and alarm diagnostics
• Advanced six-segment, twelve-step programmable logic: supports ramp-hold profiles, cyclic repetition (up to 99 loops), temperature stair-stepping, and dynamic speed modulation—all configurable with 0.1-minute resolution
• Compressor-based air-cooling system using environmentally compliant R134a refrigerant, featuring frost-free operation and adaptive cooling power modulation to maintain precise setpoints from 4 °C to 60 °C
• Triple-layer safety architecture: hardware-redundant thermal cutoffs (independent adjustable overtemperature protector + fixed safety limiter), door-interlocked motor shutdown, low-water auto-shutoff, and Class I leakage protection per IEC 61010-1
• Maintenance-free AC induction motor with constant-torque output across 30–300 rpm range; no carbon brushes, zero lubrication requirements, and <5 dB(A) acoustic emission at 200 rpm
• Electropolished stainless-steel interior and reinforced tempered glass viewing window ensure long-term resistance to biofilm adhesion, chemical exposure, and mechanical abrasion

Sample Compatibility & Compliance

The ZWYR-2112B accommodates standard laboratory vessels—including Erlenmeyer flasks (100–1000 mL), culture tubes, and deep-well plates—via interchangeable stainless-steel universal clamps and spring-loaded platforms. Its dual-shelf design allows parallel processing of heterogeneous sample types under differentiated thermal and agitation conditions. The unit complies with key international standards for laboratory equipment: IEC 61010-1 (Safety Requirements for Electrical Equipment), ISO 13485 (Medical Device Quality Management), and ASTM E1933-22 (Standard Guide for Calibration of Laboratory Incubators and Shakers). For regulated environments, optional firmware enables audit-trail logging of all parameter changes and alarm events—supporting FDA 21 CFR Part 11 compliance when paired with validated electronic signature protocols.

Software & Data Management

Embedded firmware provides non-volatile parameter storage with AES-256 encryption for user-defined programs and calibration offsets. All operational data—including temperature/speed history, alarm timestamps, and cycle completion logs—are timestamped and exportable via RS-232 serial interface to LIMS or ELN systems. The integrated thermal printer produces hard-copy records of run summaries, including start/stop times, setpoints, deviations, and operator ID (if configured). Remote monitoring is achievable through optional Ethernet module (not included), enabling integration into centralized lab infrastructure management platforms compliant with IEEE 11073-10201 for medical device interoperability.

Applications

This shaker serves critical roles in academic research, pharmaceutical development, clinical diagnostics, and industrial biotechnology. Typical use cases include aerobic bacterial growth (e.g., E. coli expression cultures), yeast fermentation optimization, mammalian cell line expansion under hypothermic conditions (e.g., 30 °C for CHO suspension), antigen-antibody binding assays requiring precise thermal ramping, and environmental microbiology studies involving temperature-gradient stress testing. Its wide speed range and stable low-speed performance (30 rpm) also support gentle tissue dissociation protocols and embryoid body formation in stem cell differentiation workflows.

FAQ

Does the ZWYR-2112B support remote control or network connectivity?
The base configuration includes RS-232 for local data export and printer interfacing. Optional Ethernet or Wi-Fi modules are available for remote parameter adjustment and real-time telemetry—subject to site-specific IT security review.
Can programming sequences be exported or backed up externally?
Yes—via RS-232, users may retrieve stored programs as ASCII-formatted text files compatible with spreadsheet analysis or version-controlled documentation systems.
Is validation documentation (IQ/OQ/PQ) provided?
Factory-issued installation and operational qualification templates are supplied. Performance qualification must be executed on-site per user-defined acceptance criteria aligned with ISO/IEC 17025 or internal SOPs.
What maintenance intervals are recommended?
No scheduled motor maintenance is required. Annual verification of temperature/speed calibration against NIST-traceable standards is advised. Condenser coil cleaning every six months ensures optimal cooling efficiency.
Are custom tray configurations available?
Yes—Zhicheng offers OEM-compatible stainless-steel trays with specialized clamping geometries (e.g., microplate holders, tube racks, or custom bore patterns) upon request with engineering review.
