Zhicheng ZWYR-240 Benchtop Full-Color Touchscreen Incubator Shaker

Overview

The Zhicheng ZWYR-240 Benchtop Full-Color Touchscreen Incubator Shaker is an engineered solution for precise, reproducible, and programmable temperature-controlled orbital agitation in life science laboratories. Designed around a high-fidelity PID microprocessor control system with real-time environmental scanning, the instrument delivers stable thermal regulation and consistent rotational motion across its full operating range—from low-temperature microbial culture maintenance (4 °C) to high-yield enzyme reaction incubation (60 °C). Its orbital drive mechanism ensures uniform fluid mixing and suspension of sensitive biological samples—including bacterial cultures, mammalian cells, yeast, and recombinant protein expression systems—without shear-induced damage typical of reciprocating or vortex shakers. The unit integrates forced-air convection for rapid temperature equilibration and homogeneous chamber distribution, validated to ≤±1 °C uniformity at 37 °C—a performance benchmark aligned with ISO 13485 and CLSI EP23 guidelines for incubator qualification.

Key Features

• 4.3-inch high-resolution TFT color touchscreen (480×272 pixels, 65K-color palette) with intuitive graphical user interface supporting animated status feedback and multilingual navigation (English language firmware standard)
• Advanced 9-segment × 18-step programmable logic: each segment configurable as ramp or hold phase; individual step duration up to 999.9 minutes; up to 99 repeat cycles for complex kinetic protocols (e.g., temperature-gradient fermentation or staged induction)
• Dual-mode operation: fixed-parameter mode for routine assays and fully programmable mode for GLP-compliant method development
• Triple-layer safety architecture: (1) Personnel protection via Class I insulation, earth leakage circuit breaker (ELCB), and overcurrent cutoff; (2) Sample integrity assurance through redundant speed/temperature watchdog circuits that trigger immediate shutdown upon deviation; (3) Equipment protection via independent mechanical overtemperature limiter, frost-free compressor thermal overload monitoring, and automatic heater deactivation on sensor failure
• Integrated thermal printer (RS-232 interface) for real-time audit trail generation—supports FDA 21 CFR Part 11–compliant record retention when paired with validated data management software
• Configurable operational parameters: incubation enable/disable, cooling enable/disable, power-loss recovery, door interlock activation, print output toggle, and user-access level encryption

Sample Compatibility & Compliance

The ZWYR-240 accommodates standard laboratory vessels including Erlenmeyer flasks (up to 2 L), test tubes, deep-well plates, and culture bottles mounted on a single 400 mm × 370 mm stainless-steel platform with non-slip silicone matting. Its Φ0–50 mm infinitely adjustable orbit diameter enables optimization for low-volume high-density suspensions (e.g., E. coli expression) or large-volume aeration requirements (e.g., Pichia pastoris fermentation). The chamber complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets ambient operating limits per ISO 15195:2018 (environmental class 1: 5–25 °C ambient). Temperature calibration traceability follows NIST-traceable standards; optional IQ/OQ documentation packages available for GMP-regulated environments.

Software & Data Management

While the ZWYR-240 operates autonomously via embedded firmware, its RS-232 serial interface permits bidirectional communication with external PCs running third-party laboratory information management systems (LIMS) or custom Python/Matlab scripts. All programmed methods—including ramp rates, dwell times, setpoints, and alarm thresholds—are stored in non-volatile memory with timestamped parameter logging. The built-in thermal printer outputs chronological records of temperature, speed, elapsed time, and fault events—serving as primary evidence for internal audits under ISO/IEC 17025 or CAP accreditation requirements. Firmware updates are delivered via USB flash drive, maintaining version control and change history per ALCOA+ principles.

Applications

This incubator shaker supports critical workflows across academic research, biopharmaceutical development, and clinical diagnostics. Typical use cases include: aerobic bacterial growth (e.g., Bacillus subtilis sporulation studies), recombinant protein expression in autoinduction media, hybridization kinetics in molecular diagnostics, mycelial expansion in fungal bioprocessing, and stability testing of therapeutic monoclonal antibodies under accelerated conditions. Its 4 °C capability supports cold-adapted enzyme characterization, while 60 °C operation enables thermophilic culture propagation and denaturation-reannealing assays. Regulatory-aligned validation protocols (e.g., USP , ASTM E2500) can be executed using its programmable temperature gradients and precision timing.

FAQ

Is the ZWYR-240 compliant with FDA 21 CFR Part 11 for electronic records?
Yes—when used with validated third-party software that implements electronic signatures, audit trails, and role-based access control, the device’s RS-232 output and thermal print logs meet predicate rule requirements for record integrity.
Can the shaker operate continuously at 4 °C without frost accumulation?
Yes—the air-cooled R134a refrigeration system employs power-regulated compressor modulation and active defrost cycling, ensuring frost-free operation over extended periods.
What is the maximum flask size supported on the platform?
Two 2 L Erlenmeyer flasks (with proper balancing) or up to eight 500 mL flasks; load distribution must remain within ±5 mm center-of-gravity offset from platform center.
Does the unit support external temperature probe input for chamber mapping?
No—temperature sensing is internal only; however, optional calibrated PT100 probes can be inserted through the chamber’s auxiliary port for independent verification during qualification.
Is remote monitoring possible via Ethernet or Wi-Fi?
Not natively—the RS-232 interface requires a USB-to-serial adapter and host PC for remote supervision; no onboard network stack is included.
