In the pharmaceutical industry, stability testing is a critical component of drug development and quality control. According to ICH Guidelines (Q1A - Q1F), drug substances and products must be tested under various climatic conditions to determine their shelf life and storage requirements. Custom stability chambers designed by Huanyi Instruments provide the controlled environments necessary to simulate these conditions with unmatched precision.
As a leading supplier and factory, we recognize that "off-the-shelf" solutions often fail to meet the complex needs of modern biopharmaceuticals, especially for vaccines and gene therapies requiring ultra-precise humidity control and specialized light exposure (photostability).
Dongguan Huanyi Instruments Technology Co., Ltd. was established on March 20, 2007, covering an area of 6,022 square meters. It is a high-tech enterprise integrating R&D, production, sales and after-sales service. It participated in the drafting of national standards and industry standards for environmental simulation test equipment.
Our philosophy is "customer-centric, quality-guaranteed, honesty-based, and innovation-oriented". Through unremitting efforts, Huanyi has cultivated a high-quality team with rich production, R&D and management experience. With the persistent efforts of all staff, our products have been selling to Southeast Asia, Europe, the United States, the Middle East and other regions, and have gotton good feedback from customers.
The next generation of stability chambers integrates machine learning algorithms to predict compressor failure or sensor drift before they occur, ensuring 100% uptime for long-term pharmaceutical studies.
Compliance with FDA 21 CFR Part 11 is now standard. Our chambers feature real-time cloud synchronization, providing immutable audit trails and remote monitoring capabilities.
With global GWP (Global Warming Potential) regulations tightening, our R&D focuses on natural refrigerants (like CO2 or hydrocarbons) and vacuum insulation panels to reduce carbon footprints.
Leveraging Dongguan's advanced manufacturing ecosystem, Huanyi offers unique advantages in stability chamber production.
From digital sheet metal processing to PLC programming, we control the entire value chain. This reduces lead times by 30% compared to traditional manufacturers.
The main components of all the company's products are made of internationally renowned brand components (Schneider, Mitsubishi, Bitzer) to ensure extreme performance and reliability.
By utilizing automated laser cutting and ERP systems, we provide high-precision instruments that meet European standards at a competitive price point, maximizing ROI for pharmaceutical factories.
High Quality Control from every aspect of raw material, production, installation, and commission. ISO 9001 factory manufacturing with mature technology.
With more than 20 years of experience, we have professional production and R&D personnel. Huanyi can meet large-volume production orders at any time.
Modern equipment including laser cutting panels, ERP systems, and production control systems help us reduce waste and ensure timely delivery.
State-of-the-art facilities ensuring every stability chamber meets international pharmaceutical standards.

ICH Q1A(R2) defines four zones: Zone I (Temperate), Zone II (Subtropical), Zone III (Hot/Dry), and Zone IV (Hot/Humid). Our chambers are programmable to meet all Zone IVb requirements (30°C/75% RH) which is the most stringent.
Our control systems use 21 CFR Part 11 compliant software, featuring electronic signatures, multi-level user access, and encrypted data logging that cannot be altered.
Yes, we have established a global network and provide 24/7 technical support. Our engineers can perform on-site IQ/OQ/PQ validation to ensure compliance with local regulatory bodies (FDA, EMA, TGA).
Long-term testing (e.g., 25°C/60% RH) determines the actual shelf life, while accelerated testing (e.g., 40°C/75% RH) speeds up chemical degradation to predict long-term stability in a shorter timeframe (usually 6 months).
