Why Stability Chamber Reliability Matters in Pharmaceutical R&D

In the pharmaceutical industry, the reliability of a stability chamber directly affects the accuracy of drug stability data, regulatory compliance, and product launch timelines. A high-performance pharmaceutical stability chamber must maintain precise environmental control for years without interruption.

For pharmaceutical manufacturers and research laboratories, choosing the right walk-in stability chamber is more than an equipment investment — it is a long-term safeguard for valuable samples, validated testing processes, and production continuity.

With years of industry expertise, Labonce has become a trusted partner for pharmaceutical companies worldwide through durable product quality, GMP-compliant chamber systems, and responsive after-sales technical support.

Recently, the Labonce China customer service team conducted on-site return visits to multiple pharmaceutical laboratories to inspect equipment performance and provide technical assistance. 

Case Study 1: Zambon Pharmaceutical — 16 Years of Stable Operation Without Major Failure

Zambon is known for its exceptionally strict standards regarding laboratory equipment stability and reliability.

Back in 2010, after extensive evaluation and supplier comparison, Zambon selected a Labonce pharmaceutical stability chamber for its laboratory operations.

What impressed the Labonce service team during the recent visit was remarkable:

• The chamber manufactured in 2010 is still operating continuously in the laboratory today
• No major equipment failures have occurred during its entire service life
• Core performance indicators remain compliant with national pharmaceutical standards
• The equipment exterior and internal components remain in excellent condition after 16 years of use

Long-Term Reliability Reduces Pharmaceutical Risk

For pharmaceutical companies, long-term equipment stability offers several critical advantages:

• Reduced maintenance and replacement costs
• Lower risk of data loss during stability studies
• Improved laboratory operational efficiency
• Greater confidence during GMP audits and regulatory inspections
• Continuous environmental consistency for sensitive samples

The successful 16-year operation of this Labonce drug stability test chamber has strengthened Zambon’s trust in the brand. As part of its latest production expansion project, the company plans to purchase a larger walk-in stability chamber from Labonce to support future pharmaceutical stability testing requirements.

Case Study 2: Emergency Maintenance Support for Walk-In Stability Chamber

At another pharmaceutical customer, Haishen Tongzhou Pharmaceutical, several Labonce pharmaceutical stability chambers are operating 24/7 for continuous testing applications.

During the on-site inspection, the laboratory manager reported that most chambers were functioning perfectly. However, one 40 m³ walk-in stability chamber that had been in operation for six years recently experienced:

• Slower humidification performance
• Poor drainage efficiency

Rapid Technical Diagnosis and Immediate Support

Labonce technical engineers immediately conducted a comprehensive inspection and quickly identified the root cause:

The chamber’s water tank had only been cleaned once in six years, causing severe scale buildup inside the water circulation system. The accumulated mineral deposits restricted water flow and affected both humidification and drainage performance.

Because the customer was conducting critical pharmaceutical stability studies, any prolonged downtime could have resulted in:

• Loss of valuable test samples
• Delayed R&D timelines
• Interrupted GMP testing processes
• Significant financial losses

To minimize operational risk, the Labonce service team arranged emergency maintenance support early on May 9.

Complete Water System Restoration

The technical engineers performed a full maintenance procedure, including:

• Disassembling the chamber water circulation system
• Removing stubborn scale deposits from pipes and tanks
• Deep-cleaning the humidification module
• Recalibrating humidity control systems

Performing complete performance testing and preventive maintenance

After several hours of intensive work, the chamber’s humidification and drainage functions returned to normal operation.
