Shanghai Yiheng GHP Series Water-Jacketed Temperature-Controlled Incubator

Overview

The Shanghai Yiheng GHP Series Water-Jacketed Temperature-Controlled Incubator is engineered for precise, stable, and contamination-minimized cell culture, microbiological growth, and biochemical incubation applications in academic laboratories, pharmaceutical QC facilities, and biotechnology R&D environments. Unlike forced-air incubators, the GHP series employs a water-jacketed heating architecture—where temperature-stabilized water circulates around the inner chamber—to deliver exceptional thermal inertia and spatial uniformity. This design ensures minimal temperature fluctuation during door openings or power interruptions, maintaining experimental integrity across extended incubation cycles. The system operates within a controlled range of RT+5°C to 65°C, with verified uniformity of ±0.5°C at the standard reference point of 37°C—meeting baseline performance expectations for ISO 13485-aligned cell culture workflows and CLSI-recommended microbial incubation protocols.

Key Features

• Stainless steel interior chamber with seamless, radius-rounded corners and removable adjustable shelves—designed for full accessibility, ease of sterilization, and compliance with GLP cleaning validation requirements.
• Water-jacketed thermal management system providing passive heat retention; maintains chamber temperature stability for >30 minutes after power loss (tested per IEC 61000-4-11 voltage dip conditions).
• Intelligent safety interlock: Opening the tempered glass observation door automatically suspends heating and fan circulation—preventing thermal shock and moisture loss during routine sample inspection.
• Self-tuning PID microprocessor controller with 0.1°C resolution and ±0.3°C temperature fluctuation tolerance—eliminates overshoot during ramp-up and supports reproducible setpoint transitions.
• Automatically modulated internal circulation fan: Speed dynamically reduces to optimal airflow velocity (<0.2 m/s) once target temperature is achieved—minimizing evaporation from open Petri dishes and preventing desiccation of sensitive monolayers.
• Optional N-series multi-segment programmable LCD controller: Enables up to 30 programmable steps with independent settings for temperature, fan speed, dwell time, ramp rate, and auto-start/standby/shutdown scheduling—supporting complex protocols such as synchronized differentiation assays or circadian rhythm studies.

Sample Compatibility & Compliance

The GHP series accommodates standard culture formats including T-flasks (up to T225), multi-well plates (6–96-well), Petri dishes (Ø35–150 mm), roller bottles, and glass culture tubes. Chamber dimensions scale across models (50 L to 270 L), enabling configuration-specific validation per ASTM E2875-22 (Standard Guide for Validation of Incubators). All units comply with GB/T 23794–2009 (Chinese national standard for incubators) and incorporate dual-level thermal safeguards: primary PID control + independent mechanical overtemperature cutoff (adjustable up to 70°C). Optional UV-C germicidal irradiation (254 nm, 15 W) provides non-chemical surface decontamination between runs—validated against ISO 14644-1 Class 5 airborne microbial reduction targets.

Software & Data Management

While the base model features standalone microcontroller operation, the N-series variant supports RS-485 Modbus RTU communication for integration into centralized lab monitoring systems (e.g., LabVantage, Siemens Desigo CC). Audit trail functionality—including timestamped parameter changes, door-open events, alarm triggers, and temperature deviation logs—is retained locally for ≥30 days. When paired with optional data logging modules (sold separately), the system meets FDA 21 CFR Part 11 requirements for electronic records via user-access controls, digital signature capability, and immutable event history export (CSV/Excel).

Applications

• Mammalian and insect cell line maintenance (HEK293, CHO-K1, Sf9) under CO₂-free conditions
• Bacterial and fungal culture (E. coli, S. aureus, C. albicans) per CLSI M07-A10 guidelines
• Enzyme activity assays requiring strict thermal consistency
• Seed germination and plant tissue culture under defined hygrothermal conditions
• Stability testing of biologics intermediates per ICH Q5C recommendations
• Quality control incubation for raw material sterility testing (USP )

FAQ

What is the difference between water-jacketed and air-jacketed incubators?
Water-jacketed designs provide superior thermal stability and recovery due to high specific heat capacity of water—ideal for unattended overnight runs or environments with ambient fluctuations.
Does the GHP series support humidity control?
Yes—integrated humidification system maintains relative humidity ≥90% RH at 37°C (optional on select configurations; requires external deionized water supply).
Can the incubator be validated for GMP use?
Yes—design includes traceable calibration ports, uniformity mapping points, and configurable alarm thresholds compatible with IQ/OQ/PQ documentation frameworks.
Is remote monitoring available?
RS-485 interface enables connection to building management systems or SCADA platforms; Ethernet/WiFi modules are available as third-party add-ons.
What safety certifications does the unit hold?
Complies with GB 4793.1–2019 (Safety requirements for electrical equipment for measurement, control, and laboratory use) and CE-marked per EN 61010-1:2010.
