Q1: How does this GMP Grade A pass box ensure sterile vial transfer while maintaining compliance with strict pharmaceutical standards?
A1: This pass box is designed to meet GMP Grade A requirements, ensuring aseptic conditions for vial transfer. It features HEPA H14 filters (≥99.995% efficiency at capturing particles ≥0.3μm) and a unidirectional laminar airflow system that creates a Class 5 clean zone. The 600mm-wide clean zone accommodates multiple vials or small batches, while stainless steel 304 construction provides a smooth, non-porous surface that resists particle buildup and is easy to sanitize. Automatic interlocking doors prevent cross-contamination, and optional UV-C sterilization further eliminates microbial risks. This design ensures compliance with GMP Annex 1 and EU/FDA regulations, critical for sterile pharmaceutical manufacturing.
Q2: Can the 304 stainless steel construction withstand frequent sanitization and harsh pharmaceutical environments?
A2: Yes. 304 stainless steel is corrosion-resistant and durable, making it ideal for pharmaceutical settings where frequent cleaning with aggressive disinfectants is required. Its smooth finish prevents dust and residue accumulation, simplifying maintenance and reducing the risk of contamination. The pass box’s welded seams and airtight seals ensure structural integrity even with daily sanitization. For highly corrosive applications, optional 316L stainless steel upgrades are available. Regular filter replacements (HEPA filters: 12–18 months) and gasket inspections maintain performance, ensuring long-term reliability in demanding cleanroom environments.
Q3: How does the 600mm clean zone in this pass box optimize vial transfer efficiency for pharmaceutical operations?
A3: The 600mm-wide clean zone is specifically designed to accommodate standard vial trays or multiple small containers, streamlining batch transfers without compromising sterility. The laminar airflow system provides uniform coverage across the entire zone, ensuring rapid particle removal from vials or equipment. The pass box’s compact footprint fits seamlessly into existing cleanroom layouts, while its ergonomic design allows easy access for operators. By minimizing the need for manual handling or resterilization, the 600mm clean zone reduces downtime and enhances productivity in high-throughput pharmaceutical packaging or labelling processes.
