The Alpha® Swab with Long Handle is widely recommended for surface sampling and cleaning validation work - this ultraclean swab provides a neutral background for the sample obtained. This swab can replace typical long-handled cotton swabs in applications requiring superior cleanliness. Also an excellent general purpose swab for cleaning surfaces and hard-to-reach areas.
Its cleanroom laundered, knitted Alpha® polyester head is extremely clean and features a double layer for additional body and extra sorbency. Low particle generation and extractable levels. This 100% continuous-filament polyester is heat-molded (thermally bonded), eliminating the need for contaminating adhesives and sealing exposed edges for reduced fiber release. Ultralow nonvolatile residue and low particle and fiber generation.
A long propylene handle (5.728" length) and flexible internal head paddle provide good support. Good sorbency and chemical compatibility. May be sterilized by autoclave.
