Molecular Traps: Molecular Traps TM are highly activated molecular sieve packets designed to provide and maintain very low water levels in solvents and solutions . Optimize for oligonucleotide synthesis, Molecular Traps TM are a convenient, dust and lint free, way of adding molecular sieves to many solvents and organic solutions. They can generally be used in any application where molecular sieves are utilized to dehydrate or maintain anhydrous solvents through repeated air exposures.
Use tested on ABI and MilliGen/PerSeptive DNA synthesizers, Molecular Traps TM will maintain sub-50 ppm water levels in the acetonitrile and activator (tetrazole) bottles directly of the instrument without fear of clogging valves or restrictors with sieve dust or pouch fuzz. Used directly in 4 litre solvent bottles, they provide a ready source of dry solvent for amidite dilution or other bench work, without the cost of discarding half-used bottles or buying many separate, small, bottles. Molecular Traps TM are available in several sizes for bottles from 50 ml through 4 liters with varying degrees of water content.
