Blackburn - Inside/Outside Purge Squeegee Kit

Inside/outside purge-squeegee kits allow for easy and more accurate transfer of sample to jar to avoid spillage and contamination.  A unique inside/outside squeegee attachment cleans the tube while making the extraction.  The ability to squeegee off the inside and outside of a coliwasa prevents excess drippage and mess.  It also renders the coliwasa 97% clean.
