Utilised to dehydrate or maintain anhydrous solvents and organic solutions which have been exposed to repeatedly to air and ‘sieves’ solution free of small contaminants. Use tested on selected DNA synthesizers, Molecular Traps will maintain sub-50 ppm water levels in the acetonitrile and activator bottles directly on the instrument without issues of clogging valves or restrictors with sieve dust or pouch ‘fuzz’.
