Description
The Large Alpha® Sampling Swab is a polyester swab specifically engineered for cleaning validation using analytical techniques such as HPLC and UV/visible spectroscopy. The laundered, knitted polyester head provides sampling with minimal background contamination. A long, rigid handle and internal head paddle provide firm support and even contact with the sampling area. The swab handle is notched so the head can easily be snapped off for convenient sample handling. The Large Alpha Sampling Swab is not appropriate for TOC analysis.
