The equipment numbering system for drug stability test chambers uses a combination of letters and numbers to intuitively reflect the functional characteristics, compliance standards, and volume parameters of the equipment. The following is a detailed analysis of the numbering rules:

1. Basic Function Identification

1) LGS: Low humidity, GMP, Stability chamber (GMP stability chamber with low humidity function, 20%RH)

2) CGS: Combined, GMP, Stability chamber (GMP stability chamber with combined lighting system, compliant with ICH and Chinese Pharmacopoeia)

3) FC: Frequency Conversion (Frequency conversion function)

2. High-Precision Model Identification

1) FS: FDA/ICH, Stability chamber (Stability chamber with higher control accuracy and uniformity, compliant with FDA/ICH standards)

2) CFS: Combined, FDA, Stability chamber (High-precision stability chamber with combined lighting system)

3. Volume Identification

The internal volume is directly indicated by numbers (unit: liters/L):

1) 150GS-FC: 150L GMP stability chamber (with frequency conversion)

2) 5000GS-FC: 5000L GMP stability chamber (with frequency conversion)

3) 10000GS-FC: 10000L GMP stability chamber (with frequency conversion)

4. Multi-Chamber Independent Control Models

1) Dual-Chamber:

320GS: 150L + 150L (Upper and lower temperature/humidity chambers)

520GS: 250L + 250L (Left and right temperature/humidity chambers)

2) Triple-Chamber:

430GS: 100L + 100L + 230L (Three temperature/humidity chambers)

430CGS: 100L + 100L + 230L (Chamber A: Temperature + lighting; Chambers B/C: Temperature + humidity)

The numbering system of Labonce is clearly reflects the core functions (e.g., GMP compliance, lighting system, frequency conversion), performance levels (e.g., high-precision FS series), and volume parameters through letter abbreviations and number combinations, facilitating quick identification and selection by users.
