The previous amber polypropylene autosampler vials (Catalog # 9502S-PP-AMBER) have been discontinued due to material instability that resulted in unpredictable color changes.
They have been replaced with Catalog # 9502S-PP-AM. These updated vials may appear more opaque, which is normal and reflects improvements in material consistency and performance.
