The Large Alpha Swab is a polyester swab for cleaning broad surfaces and flat areas. Its laundered, knitted Alpha polyester head is extremely clean. A long, rigid handle and large internal head paddle provide firm support. The Alpha Swab is widely recommended for surface sampling and cleaning-validation work. Its cleanliness levels provide a neutral background for the sample obtained. This swab is an ideal choice for controlled cleaning and sampling of large areas.
