Introduction: The Critical Role of Stability in Pharma

In the pharmaceutical industry, stability testing is not just a procedural step—it is the backbone of patient safety and product efficacy. Whether determining shelf life or evaluating storage conditions, the equipment used must deliver unwavering precision.

For GMP-certified laboratories, the challenge is twofold: maintaining precise environmental conditions (Temperature/Humidity/Light) and ensuring absolute Data Integrity.

This guide explores how the Labonce-GS/FS and CGS Series are engineered specifically to meet the rigorous demands of ICH Q1A, ICH Q1B, and FDA 21 CFR Part 11, making them the preferred choice for scientific research and drug production departments.

1. Meeting ICH Q1A Standards: The Labonce-GS/FS Series

The ICH Q1A (R2) guideline dictates that stability testing for new drug substances must be conducted under specific temperature and humidity conditions over long periods. Fluctuations can invalidate months of data.

Precision Through Structural Innovation

The Labonce-GS and FS Series (Drug Stability Chambers) address this through a newly designed air-way system. Unlike standard chambers that may have hot or cold spots, Labonce utilizes a three-sided airflow design that ensures uniform distribution across all shelves.

• Temperature Fluctuation: Controlled strictly within < ±0.5℃.

• Temperature Deviation: Maintained at < ±2.0℃.

• Humidity Deviation: Kept within < ±3%RH.

This level of precision ensures that whether you are testing at 25℃/60%RH (Long-term) or 40℃/75%RH (Accelerated), the environment remains stable, protecting your samples from "drifting" out of specification.

2. Solving the Data Integrity Puzzle (FDA 21 CFR Part 11)

In the modern GMP lab, "if it isn't documented, it didn't happen." The most significant pain point for auditors is data tampering or gaps in logging.

Labonce chambers are equipped with a proprietary Audit Tracking System designed specifically for FDA 21 CFR Part 11 compliance.

Key Compliance Features:

1. Three-Level User Authority: The system supports hierarchical login permissions (Operator, Administrator, QA), ensuring that unauthorized personnel cannot alter test parameters.

2. Uneditable Data Export: Data can be exported via a USB flash drive in a secure electronic text format that cannot be modified, satisfying audit requirements for data permanence.

3. Long-Term Storage: For the JS and high-end series, the system supports SD card storage capable of holding over 5 years of electronic text data, ensuring historical records are always retrievable.

3. Photostability Testing: The Labonce-CGS/TPS Advantage

For light-sensitive drugs, compliance shifts to ICH Q1B. This requires exposing the drug substance to specific zones of light (Visible and Near-UV).

The Labonce-CGS and TPS Series integrate these requirements into a single unit, removing the guesswork from photostability testing.

• Dual Light Sources: Equipped with Visible Light (D65) and Near-Ultraviolet (UV) lamps.

• Automatic Illuminance Control: The chamber automatically adjusts and monitors light intensity to ensure samples receive the required exposure dose without overheating.

• Programmable Operation: Users can set specific light exposure cycles, allowing for automated "lights off" once the cumulative dose is reached.

4. Built for Reliability: Minimizing Downtime

In a stability test that lasts 6 to 12 months, equipment failure is a disaster. Labonce engineers its chambers for "long-term continuous operation".

Durability Features:

• High-Quality Materials: The exterior is coated high-quality steel, while the inner liner is made of mirror stainless steel 304. This material is pollution-free, easy to clean, and resistant to corrosion.

• Dual Compressor Technology: Selected models feature two independent compressor systems. If one fails, the other takes over, ensuring the test continues uninterrupted.

• Insulation: High-density polyurethane foam technology provides superior insulation, reducing the workload on the compressor and ensuring moisture retention.

Safety Alarms:

To protect valuable samples, the system includes:

• Independent Over-temperature Protection: Prevents thermal runaway.

• SMS Alarm System: Optional modules can send text alerts to lab managers in case of deviations.

• Water Shortage & Fan Overheating Alarms: Proactive alerts to prevent mechanical failure.

Conclusion: Why Choose Labonce for Stability?

Selecting a stability chamber is a decision that balances cost, performance, and compliance risk. Labonce stands out by offering a "turnkey" solution for GMP compliance.

With ICH-compliant precision, FDA-ready data integrity features, and robust construction, the Labonce-GS/FS and CGS series provide the peace of mind required for critical pharmaceutical testing.
