When it comes to pharmaceutical and biotech stability testing, standard reach-in cabinets are often insufficient for large-scale production or extensive batch sampling. This is where a walk-in stability chamber (also known as a pharmaceutical constant temperature and humidity room) becomes essential.

Based on the highly reliable Labonce-GS-FC Series, we have compiled the most frequently asked questions to help you understand the core capabilities of top-tier walk-in environmental chambers.

Q1: What capacity options are available for large-scale stability testing?

For laboratories handling massive sample volumes, spatial flexibility is crucial. The Labonce-GS-FC series offers an extensive internal volume ranging from 8,000L to 80,000L (8m³ to 80m³).

Whether you need the compact Labonce-8000GS-FC or the massive Labonce-80000GS-FC, the structural design allows for customizable dimensions based on your specific site layout, ensuring maximum utilization of your laboratory space.

Q2: How precise is the temperature and humidity control in a walk-in chamber?

Precision is the heartbeat of ICH stability testing. Utilizing an imported hermetic frequency conversion compressor and a high-precision capacitive humidity sensor (which requires zero maintenance), the Labonce-GS-FC series delivers industry-leading stability:

• Temperature Range: 20～45℃

• Temperature Fluctuation: ±0.5℃ (Deviation: ±1.0℃)

• Humidity Range: 20～80% RH

• Humidity Fluctuation: ±2.0% RH (Deviation: ±3.0% RH)

  This stable and reliable performance guarantees continuous operation without jeopardizing your sensitive samples.

Q3: Does the equipment meet FDA and GMP data compliance requirements?

Absolutely. Data integrity is a top priority for pharmaceutical testing. The Labonce-GS-FC is equipped with a large-screen color touch controller that features three levels of authority and an audit trail, fully complying with modern regulatory standards.

Furthermore, it supports:

• Data Storage: Safely stores over 5 years of temperature and humidity values.

• Data Printing: Instantly prints equipment models, numbers, and real-time temperature/humidity curves.

Q4: What safety features are critical for personnel operating inside a walk-in room?

Operator safety in a walk-in constant temperature and humidity room cannot be overlooked. The Labonce-GS-FC chamber door features a hollow glass observation window and a specialized door lock that supports internal opening—preventing any risk of personnel being trapped inside.

Additionally, the system features a fivefold protection mechanism, including a double-insurance anti-dry burning system and an independent over-temperature protection system that automatically cuts off the 380V power supply in emergencies.

Q5: What happens if there is an equipment anomaly or power failure during the night?

You don't need to monitor the chamber 24/7. The equipment is designed with a comprehensive alarm system:

• On-site Alarms: Sound and light alarms for any temperature or humidity deviations.

• Remote Alarms: A remote mobile phone SMS alarm system (including power failure alerts). Multiple devices can share a single SIM card, ensuring your team is notified instantly, no matter where they are.

Labonce-GS-FC Series Technical Specifications Summary

For quick reference, here is the technical sizing and power data for the standard models. Note: Reasonable layout can be arranged according to site-customizable dimensions.

(Note: The inner liner material is Stainless Steel 304, and the shell is constructed with polyurethane foam insulation board for optimal thermal efficiency.)
