• Ultra-clean and airtight containment
  The isolator maintains a constant internal pressure of 3–5 mbar and an oxygen/moisture concentration ≤1 ppm to ensure complete isolation of sensitive materials such as lithium battery compounds or pharmaceutical actives. The integrated gas purification and circulation system maintains a stable inert atmosphere (e.g., nitrogen), effectively preventing contamination or degradation.
• Continuous and efficient operation
  Designed for uninterrupted production, the system includes a dedicated inlet buffer and empty bottle storage chamber, enabling multiple container changes without downtime. Automatic bottle replenishment maintains workflow continuity, while filled containers are transferred directly to the next stage without disrupting the controlled atmosphere.
• Precision filling and sealing
  Equipped with a vertical auger filler driven by a servo motor and closed-loop control, it ensures high-precision filling of ±5 g for loads ≤10kg and ±10 g for loads ≤25kg. The inflatable sealing door creates a reliable airtight seal within seconds and releases easily for safe operation and zero leakage.
• Enhanced safety and automation
  The system provides complete operator isolation to prevent exposure to high-potency or toxic compounds such as pharmaceutical intermediates. Compliant with GMP and explosion-proof standards, it integrates PLC control and touchscreen operation for real-time monitoring, data recording, and MES connectivity.
• Industry-specific configurations, such as
  Lithium battery materials: Dust-free filling and metal contamination prevention
  Pharmaceutical and chemical sectors: Constructed from 316 stainless steel for easy cleaning and compliance with hygiene standards
  Toxic compounds: Negative pressure design with double-sealing barriers to eliminate leakage risk

Ideal for lithium battery production and pharmaceutical chemical industries where materials require an oxygen- and moisture-free environment. It enables safe handling and packaging of highly active, moisture-sensitive, or toxic compounds while maintaining absolute isolation and product integrity.

This weighing and dispensing isolator can be integrated with our vacuum conveying units to form a complete and enclosed material handling and packaging line, tailored to meet various production requirements.
