Sampling swabs made from the cleanest 100% polyester knit materials.

• Proprietary cleaning process reduces interference in the 230 nm range resulting in an improved limit of detection
• Double layered, double knit polyester head entraps contaminants for maximum pick up and easy release, providing excellent recovery rates
• Notched, break-away handle allows the head to be placed into the vial with minimal handling and contamination

Suitable for use in HPLC using a UV/visible detector analytical method as part of a cleaning validation protocol.
