Product Description

Our sampling and homogenizer bags are designed for reliable collection, transport and homogenization of samples in microbiological and pharmaceutical quality control. Every bag is gamma-irradiated and supplied sterile, ready for immediate use in the laboratory or on the production floor.

An integrated side filter compartment retains solids while allowing the homogenized liquid to be poured off cleanly, simplifying downstream plating and filtration.

Quality & Compliance

All Angfeilin products are manufactured in ISO Class 5–8 multi-stage cleanrooms under an ISO 9001-certified quality management system. Materials are validated against ISO 10993 biocompatibility requirements, USP particulate and endotoxin limits, and can be supplied gamma- or EO-sterilized with batch documentation. Semiconductor-grade cleanliness is verified through Outgassing, IC, FTIR, ATR and NVR testing.

Customization

Thickness, width, sealing style, sterilization method and packaging can all be adapted to your process. Send us your specifications and application scenario, and our engineering team will propose the most suitable solution.
