ZHICHENG ZXDR-2430 Precision Temperature-Controlled Incubator with 7-inch True-Color Touchscreen Interface

Overview

The ZHICHENG ZXDR-2430 is a high-reliability, microprocessor-controlled temperature incubator engineered for stable, uniform thermal environments in life science laboratories. It operates on the principle of forced-air convection with PID-based closed-loop temperature regulation—ensuring precise setpoint maintenance and minimal thermal deviation across the chamber volume. Designed for continuous operation under GLP-compliant workflows, the unit maintains temperature stability within ±0.1 °C (fluctuation) and uniformity within ±0.3–1.0 °C (spatial variation), validated per ISO 15195 and ASTM E2876 guidelines for laboratory incubators. Its 430 L working volume accommodates standard tissue culture flasks, Petri dishes, multi-well plates, and bioreactor vessels—making it suitable for cell culture, microbial propagation, enzyme activity assays, and stability testing of biological reagents.

Key Features

• 7-inch true-color TFT touchscreen display (800 × 480 resolution, 65K colors) mounted ergonomically above the door for intuitive parameter input, real-time status visualization, and contextual alarm messaging.
• PID microprocessor controller with environmental scanning algorithm for adaptive response to load changes, ambient fluctuations, and door-opening events.
• Triple-layer safety architecture: (1) Personnel protection via integrated earth-leakage circuit breaker (ELCB) and overcurrent cutoff; (2) Sample integrity safeguarded by redundant independent overtemperature cutouts (mechanical and electronic); (3) Asset protection enabled by overheat prevention circuitry that de-energizes heating elements before critical thresholds are exceeded.
• Programmable multi-step protocol capability: up to 9 segments / 18 steps with adjustable ramp rates and hold durations (0.1–999.9 min per step), supporting complex thermal profiles for differentiation studies or circadian rhythm simulations.
• Robust chamber construction: mirror-finish #304 stainless steel interior (≥1 mm thickness), electropolished stainless steel shelving (2 standard, expandable to 4), and optimized airflow ducting for laminar, low-turbulence circulation.
• Comprehensive diagnostics: sensor failure detection, upper/lower limit deviation alerts, self-calibration prompts, and event logging for audit readiness.

Sample Compatibility & Compliance

The ZXDR-2430 supports a broad range of biological and pharmaceutical samples—including mammalian and insect cell lines, bacterial and fungal cultures, hybridoma suspensions, serum-supplemented media, and temperature-sensitive reagents. Its chamber geometry and surface finish minimize particulate shedding and facilitate cleaning validation per USP <1058> and ISO 14644-1 Class 8 requirements. All electrical components comply with IEC 61010-1:2010 for laboratory equipment safety. The incubator meets CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU LVD Directive) and conforms to GB/T 23789–2009 (Chinese national standard for incubators). Optional RS-232 interface enables integration into centralized lab monitoring systems compliant with FDA 21 CFR Part 11 for electronic record integrity.

Software & Data Management

While the ZXDR-2430 operates as a standalone instrument with embedded firmware, its RS-232 serial port (optional) allows bidirectional communication with external PCs running validated data acquisition software. Logged parameters—including chamber temperature, setpoint, elapsed time, alarm events, and diagnostic flags—are timestamped and exportable in CSV format. The system supports user-defined password protection for critical settings (e.g., max temperature limit, program editing), ensuring configuration integrity during shared-lab use. Firmware includes non-volatile memory for parameter retention during power interruption, and automatic “power-resume” functionality restores pre-interruption conditions upon grid recovery—critical for long-duration assays exceeding 72 hours.

Applications

• Cell culture maintenance (adherent and suspension) at physiological temperatures (37 °C) or hypothermic conditions (25–30 °C).
• Microbial growth kinetics studies under controlled thermal regimens for QC microbiology and antimicrobial susceptibility testing.
• Enzyme thermostability profiling and protein denaturation experiments requiring precise ramp-and-hold thermal protocols.
• Stability storage of vaccines, monoclonal antibodies, and diagnostic reagents per ICH Q5C guidelines.
• Environmental simulation for ecotoxicology assays and plant tissue culture propagation.
• Pre-incubation conditioning of biosensors, ELISA plates, and lateral flow devices prior to assay execution.

FAQ

What is the maximum operating temperature range?
The incubator maintains temperatures from ambient +5 °C to 65 °C, with optimal stability performance between 20 °C and 45 °C.
Is humidity control available on this model?
No—the ZXDR-2430 is a temperature-only incubator. For humidity-enabled variants, refer to the ZXDR-H series.
Can the incubator be validated for GMP environments?
Yes—its design supports IQ/OQ/PQ execution. Documentation packages including calibration templates, alarm verification checklists, and traceable sensor certificates are available upon request.
What materials are used in chamber construction to ensure chemical resistance?
Interior surfaces are fabricated from electropolished #304 stainless steel (ASTM A240), resistant to ethanol, isopropanol, diluted acids/bases, and hydrogen peroxide vapor—compatible with common lab disinfection protocols.
Does the unit support remote monitoring via Ethernet or Wi-Fi?
Not natively—only RS-232 serial connectivity is provided. Integration with building management systems requires third-party protocol converters (e.g., Modbus RTU gateways).
