Zhicheng ZXDR-2800 Electric Constant Temperature Incubator with 7-inch True-Color Touchscreen

Overview

The Zhicheng ZXDR-2800 Electric Constant Temperature Incubator is an engineered solution for precise, stable, and reproducible thermal conditioning of biological and pharmaceutical samples in regulated laboratory environments. Built upon a robust stainless-steel architecture and grounded in fundamental thermodynamic control principles, this incubator employs a PID-driven microprocessor control system that continuously scans ambient and chamber conditions to maintain setpoint accuracy within ±0.1°C. Its operational range extends from ambient +5°C to 65°C—optimized for applications requiring non-refrigerated, elevated-temperature stability, including microbial cultivation, enzyme activity assays, cell line maintenance, and accelerated stability testing. Unlike basic benchtop units, the ZXDR-2800 integrates full environmental feedback loops, redundant thermal safeguards, and a high-fidelity 7-inch true-color touchscreen interface—enabling real-time visualization of process parameters, event logs, and active alarm states without physical instrumentation access.

Key Features

• 7-inch capacitive touchscreen display (800×480 resolution, 65K-color palette) mounted above the door for ergonomic viewing and intuitive parameter entry
• PID microprocessor controller with environmental scanning algorithm for adaptive thermal response and minimal overshoot
• Triple-layer safety architecture: (1) primary electronic leakage/overcurrent protection with automatic circuit interruption; (2) secondary mechanical overtemperature limiter (independent of main controller); (3) tertiary hardware-based overheat cutoff activated by dedicated thermal fuse
• Programmable temperature profiles supporting up to 9 segments and 18 steps, with user-defined ramp rates and hold durations (up to 999.9 minutes per step)
• Forced-air convection system with low-turbulence airflow distribution, engineered to minimize thermal gradients across the 800 L working volume
• Interior constructed from ≥1 mm thick electropolished #304 stainless steel; shelves are also #304 stainless, fully removable and adjustable (standard: 3 shelves, max. 6)
• Self-diagnostic firmware monitoring sensor integrity, upper/lower temperature limits, and power continuity—triggering audible/visual alerts and logging fault codes
• Power recovery function preserving program state and setpoints after unexpected mains interruption
• Parameter password protection and calibration offset adjustment for traceable temperature display correction

Sample Compatibility & Compliance

The ZXDR-2800 accommodates standard microbiological vessels—including Petri dishes, flasks, multi-well plates, serum bottles, and culture tubes—within its spacious, geometrically optimized chamber. The absence of sharp internal corners and seamless welds in the electropolished interior reduces particle entrapment and facilitates cleaning validation per ISO 14644-1 Class 8 requirements. While the unit itself is not CE-marked or FDA 510(k)-cleared as a medical device, its design aligns with foundational elements of Good Laboratory Practice (GLP) and current Good Manufacturing Practice (cGMP) Annex 11 expectations for equipment qualification: documented calibration traceability, configurable alarm thresholds, non-volatile parameter memory, and deterministic response to fault conditions. When paired with third-party validated data acquisition systems, it supports 21 CFR Part 11-compliant electronic record generation for temperature-critical protocols.

Software & Data Management

The onboard controller operates autonomously without external PC dependency, storing up to 100 event logs (including alarms, program starts/stops, and manual interventions) with timestamps. Optional RS-232 serial connectivity enables integration into centralized laboratory information management systems (LIMS) or SCADA platforms for remote monitoring and automated data archival. An optional embedded thermal printer provides hard-copy output of runtime summaries, alarm histories, and calibration verification reports—useful for audit preparation and batch release documentation. All user-modifiable settings—including temperature offsets, alarm thresholds, and program sequences—are protected by alphanumeric password authentication to prevent unauthorized configuration changes.

Applications

This incubator serves core functions across academic, clinical, and industrial life science workflows: sustained aerobic bacterial growth (e.g., E. coli, Bacillus subtilis), fungal culture maintenance, mammalian cell passaging at physiological temperatures, serum and reagent storage under controlled thermal conditions, accelerated degradation studies for pharmaceutical excipients, and environmental stress testing of diagnostic kits. Its uniformity performance (≤±0.3°C typical, ≤±1.0°C worst-case) meets ASTM E1757-20 criteria for “laboratory ovens and incubators used in materials testing,” while its programmable ramp-and-hold capability supports ISO 11137-defined sterilization cycle development and USP dry-heat depyrogenation validation protocols.

FAQ

What is the maximum operating temperature of the ZXDR-2800?
The unit is rated for continuous operation from ambient +5°C up to 65°C.
Does the incubator support validation documentation for GxP environments?
Yes—the controller retains timestamped event logs, supports password-protected parameter modification, and permits external data capture via RS-232; users must implement complementary IQ/OQ/PQ protocols per their quality system requirements.
Can the internal shelves be configured for larger vessels?
Standard configuration includes three adjustable stainless-steel shelves; up to six may be installed using optional support rails.
Is the touchscreen interface compatible with gloved operation?
The capacitive display responds reliably to standard nitrile and latex gloves, though pressure sensitivity may vary depending on glove thickness and moisture content.
What electrical infrastructure is required for installation?
A dedicated 220 V AC, 50/60 Hz circuit with minimum 16 A breaker capacity and proper grounding is mandatory due to the 1500 W heating load.
