Zhicheng ZWYR-2102C Dual-Layer Programmable Temperature-Controlled Orbital Shaker with Color Touchscreen

Overview

The Zhicheng ZWYR-2102C is a dual-layer programmable temperature-controlled orbital shaker engineered for high-precision, reproducible incubation and agitation of biological samples under tightly regulated thermal and mechanical conditions. It operates on the principle of orbital motion—generating uniform circular oscillation at defined amplitude (Φ26 mm) and speed (30–300 rpm)—to ensure homogeneous suspension of microbial cultures, mammalian cells, enzymatic reaction mixtures, or hybridization solutions without shear-induced damage. Integrated forced-air convection and R134a-based refrigeration enable stable temperature control from 4 °C to 60 °C, with stability ≤±0.1 °C and uniformity ≤±1 °C at 37 °C—meeting critical requirements for cell culture, fermentation kinetics, and molecular assay development. Its architecture conforms to GLP-compliant laboratory infrastructure, supporting audit-ready operation through embedded data logging, parameter encryption, and power-failure recovery protocols.

Key Features

• 7-inch full-color TFT touchscreen HMI with intuitive Chinese/graphical interface, enabling real-time visualization of temperature, speed, time, and program status—including animated progress indicators for multi-step ramp-and-hold sequences
• Dual independent overtemperature protection: one adjustable (user-settable) and one fixed (hardware-latched), both compliant with IEC 61010-1 safety standards for laboratory equipment
• Comprehensive safety suite: door-open interlock shutdown, low-water level detection with automatic cut-off, leakage current protection (≥30 mA), compressor overheat safeguard, and electronic overcurrent tripping
• Brushless AC induction motor delivering constant torque across full speed range; zero carbon brushes, no routine lubrication, and rated for >20,000 hours MTBF
• Multi-dimensional balanced drive system minimizing vibration transmission to adjacent instrumentation and ensuring long-term mechanical stability
• Frost-free refrigeration using R134a with adaptive load modulation—eliminates manual defrost cycles and maintains consistent chamber humidity during extended low-temperature operation
• Electropolished stainless-steel interior and spring-loaded universal clamps resist corrosion and accommodate diverse vessel formats (test tubes, flasks, deep-well plates)

Sample Compatibility & Compliance

The ZWYR-2102C accommodates standard microbiological and bioprocess vessels including Erlenmeyer flasks (up to 750 mL), culture tubes, and multi-well plates via interchangeable trays. Its dual-shelf configuration (2 × 496 × 350 mm) supports simultaneous parallel experiments with independent loading flexibility. The chamber’s 173 L volume and optimized airflow design ensure minimal thermal gradient across all positions—validated per ISO 13408-2 Annex B for incubator uniformity testing. All electrical and thermal safety mechanisms comply with IEC 61010-1:2010 and GB 4793.1–2007. Data integrity features—including timestamped parameter logging, user-access controls, and RS-232 output—support alignment with FDA 21 CFR Part 11 requirements when paired with validated LIMS or ELN systems.

Software & Data Management

• Onboard 6-segment × 12-step programmable logic supports complex thermal and kinetic profiles: temperature ramps, stepwise gradients, repeated cycling, and hold phases—all configurable with ramp rates (°C/min) and dwell durations up to 999.9 minutes per segment
• Embedded micro-printer provides hard-copy records of setpoints, actual values, alarms, and runtime logs—critical for SOP adherence and regulatory inspections
• RS-232 serial interface enables bidirectional communication with external PCs for remote monitoring, script-based automation (e.g., Python/PySerial), and integration into centralized lab management platforms
• Parameter memory retains all user-defined settings after power cycle; encrypted access prevents unauthorized modification of critical operational parameters
• Real-time clock synchronization ensures accurate timestamping of all logged events, satisfying GLP traceability mandates

Applications

This shaker serves core workflows in academic research, pharmaceutical QC, and industrial biotechnology laboratories. Typical use cases include aerobic bacterial growth (E. coli, Bacillus spp.), yeast fermentation profiling, protein expression in shake flasks, DNA hybridization optimization, enzyme activity assays under controlled thermal stress, and suspension cell expansion for biomanufacturing process development. Its precise low-temperature capability (4 °C) supports cold-adapted enzyme studies and sample preservation during agitation. The dual-layer design increases throughput without compromising control fidelity—ideal for comparative studies across temperature or agitation conditions, media optimization screens, or replicate bioreactor seed train preparation.

FAQ

Does the ZWYR-2102C support validation documentation (IQ/OQ/PQ)?
Yes—factory-supplied test certificates cover temperature uniformity, speed accuracy, and alarm response verification. Optional IQ/OQ protocols aligned with ASTM E2500 and EU GMP Annex 15 are available upon request.

Can the touchscreen interface be configured for English-language operation?
The firmware supports localized UI language packs; English localization is available as a factory-configurable option prior to shipment.

Is the RS-232 interface compatible with common laboratory data acquisition software?
Yes—it implements ASCII-based command-response protocol with documented SCPI-like syntax, enabling native integration with LabVIEW, MATLAB, and custom Python applications.

What is the warranty coverage and service support structure outside China?
Zhicheng provides 24-month parts-and-labor warranty. Global technical support is delivered through authorized regional distributors with certified field service engineers trained to ISO/IEC 17025 standards.

How does the low-water detection system prevent evaporative failure during long-term incubation?
An ultrasonic water-level sensor continuously monitors reservoir volume; if level falls below 15% capacity, the system halts heating and cooling functions while triggering visual/audible alerts—preventing dry-run damage to the evaporator coil and chamber insulation.
