As a key safety device, flexible isolators are widely used in pharmaceutical R & D, biotechnology, and high - cleanliness production scenarios. Through the use of highly transparent materials and flexible designs, they achieve the dual goals of efficient protection and operational visualization. Their core value lies in providing reliable solutions for personnel safety, process compliance, and cost control through the combination of innovative structures and functions.
Material and Structural Characteristics
The device uses multi - layer, highly transparent resin films (such as modified polyethylene or polyurethane) to construct the main chamber. These materials have both a light transmittance of over 98% and chemical corrosion resistance, ensuring that operators can directly observe the state of internal materials. Some models can achieve a sealing effect with an oxygen transmission rate of less than 5 cm³/m²·day through a composite polypropylene or EVOH barrier layer, which is suitable for handling sensitive substances that require inert gas protection.
Industry Application Scenarios
In the pharmaceutical field, flexible isolators mainly serve three scenarios:
1. Aseptic preparation filling lines to prevent particle contamination caused by human intervention.
2. Weighing and transferring of highly active pharmaceutical ingredients (HPAPI).
3. Closed - loop production of cell therapy products.
The negative - pressure environment design (usually maintained at - 15 to - 30 Pa) can effectively prevent the leakage of hazardous substances. Coupled with an integrated glove operation system, it meets the Class 5 cleanliness requirements of ISO 14644 - 1.
Comparison of Operational Benefits
Compared with traditional rigid isolators, the flexible system stands out in terms of cost and flexibility:
- The construction cycle is shortened by 60%, and most models support installation and verification within 72 hours.
- The single - use design avoids the cost of cleaning verification, and the annual maintenance cost is reduced by 45%.
- The modular structure is suitable for the transformation of existing production lines, and the space utilization rate is increased by 30%.
