External Nozzle Cleaning System

External Nozzle Cleaning System removes the crystallized samples accumulated on the outside of the fraction nozzles and cleans well. Cross contamination is a big concern in flash chromatography. The W-Prep-2XY-N cleans outside of the fraction nozzles as well as inside. Thus, pure fractions will always be collected. This device keeps entire solvent lines always clean. (Patent No. 4551364)
