Zhicheng ZWYR-211D Horizontal Temperature-Controlled Orbital Shaker with Touchscreen Color LCD

Overview

The Zhicheng ZWYR-211D is a high-precision horizontal orbital shaker engineered for demanding life science laboratories requiring tightly controlled, reproducible incubation and agitation conditions. It employs a PID-controlled microprocessor system integrated with environmental scanning logic to continuously monitor and dynamically adjust chamber temperature and platform rotation—ensuring minimal thermal drift and mechanical oscillation variance across extended operation periods. Designed specifically for applications where simultaneous thermal regulation and uniform orbital motion are critical—including microbial culture expansion, enzyme kinetics assays, hybridization protocols, and suspension cell propagation—the ZWYR-211D delivers stable performance within a 4–60 °C temperature range and 30–300 rpm speed envelope. Its forced-air convection architecture, combined with an air-cooled R134a refrigeration module, enables rapid cooldown and precise sub-ambient stabilization without frost accumulation, supporting both ambient and low-temperature workflows in compliance with ISO 13485-aligned manufacturing environments.

Key Features

• 7-inch full-color TFT touchscreen HMI with bilingual (Chinese/English) support and animated graphical interface for intuitive parameter navigation, real-time status visualization, and multi-step protocol editing
• Advanced 6-segment × 12-step programmable controller enabling complex thermal and kinetic profiles—including ramp-and-hold temperature gradients, speed transitions, and cyclic incubation sequences (up to 99 repeats per program)
• Dual independent safety systems: adjustable overtemperature cutoff (hardware-based), plus software-monitored upper/lower limits for both temperature and rotational speed
• Foot-actuated front access door with automatic motor shutdown upon opening—preventing accidental exposure to moving components and preserving sample integrity
• Low-water-level detection circuitry that triggers immediate power cutoff to protect heating elements and prevent dry-run damage to the chamber liner
• Brushless AC induction motor with constant-torque output across full speed range; maintenance-free operation with no carbon brushes or lubrication requirements
• Gradual acceleration/deceleration algorithm minimizing mechanical shock to sensitive biological samples during startup and stop phases
• Electrostatically coated steel chassis with mirror-polished stainless-steel interior, electropolished platform, and removable spring-loaded flask clamps—designed for corrosion resistance and ease of decontamination under GLP/GMP cleaning validation protocols

Sample Compatibility & Compliance

The ZWYR-211D accommodates a broad spectrum of vessel formats—from standard Erlenmeyer flasks (250–5000 mL) to deep-well plates and custom bioreactor vessels—via its large 940 × 584 mm platform and modular clamp system. Its 286 L internal volume supports high-throughput cultivation while maintaining uniform airflow distribution and thermal homogeneity (≤ ±1.0 °C at 37 °C). The unit conforms to IEC 61010-1:2010 for laboratory equipment safety and incorporates electrical protections compliant with EN 60335-1. All firmware operations—including parameter logging, alarm history, and print output—support audit trails required for FDA 21 CFR Part 11–aligned data integrity frameworks when paired with validated RS-232 communication software.

Software & Data Management

Embedded firmware provides non-volatile parameter memory with password-protected encryption, ensuring method consistency across user sessions and preventing unauthorized configuration changes. Real-time clock synchronization enables timestamped event logging (e.g., door openings, temperature excursions, speed deviations), stored locally and exportable via RS-232 to external LIMS or ELN platforms. The integrated thermal microprinter produces hard-copy records of operational parameters, alarm events, and final cycle completion—critical for QC documentation in pharmaceutical stability testing or clinical microbiology labs. Optional PC-based configuration utilities allow remote firmware updates, batch protocol deployment, and CSV-formatted data archival compatible with statistical process control (SPC) analysis tools.

Applications

This shaker serves as a core platform in academic research, biopharmaceutical development, and diagnostic assay optimization. Typical use cases include aerobic bacterial growth in nutrient broth (e.g., E. coli expression cultures), yeast fermentation monitoring, mammalian suspension cell passaging, antibody production in CHO bioreactors, and DNA hybridization kinetics under controlled thermal ramping. Its programmable temperature-staircase functionality supports ASTM D5517-compliant biodegradability studies, while its precision speed control meets USP requirements for dissolution media agitation in formulation development. Environmental labs utilize it for BOD incubation per ISO 5815-1, and food safety units deploy it for pathogen enrichment per AOAC 977.27.

FAQ

Does the ZWYR-211D support remote monitoring via Ethernet or Wi-Fi?
No—this model includes only RS-232 serial connectivity. Ethernet or wireless interfaces are not integrated but may be enabled via third-party serial-to-Ethernet converters certified for industrial lab use.
Can the unit operate continuously for more than 500 hours?
Yes—the 500-hour timer is a single-cycle limit; after expiration, the device halts unless reprogrammed. For unattended long-term runs, users configure recurring programs or enable power-fail recovery to resume from last known state.
Is the refrigeration system serviceable on-site by qualified technicians?
The R134a circuit is sealed and requires EPA-certified refrigerant handling credentials for any pressure-side intervention. Routine maintenance (filter cleaning, door seal inspection, platform calibration) is field-serviceable without specialized HVAC tools.
What validation documentation is supplied with the instrument?
Factory-issued IQ/OQ documentation templates, traceable calibration certificates for temperature and speed sensors (NIST-traceable), and electrical safety test reports are provided. Full GMP-compliant PQ execution support is available through Zhicheng’s authorized service partners.
Are replacement parts such as the touchscreen or compressor available separately?
Yes—all major subassemblies—including the HMI module, refrigeration compressor, PID controller board, and platform assembly—are stocked globally through Zhicheng’s distributor network with lead times under 4 weeks.
