Glass Bodied Indicating Moisture Traps

Trigon glass moisture traps are impervious to the infusion and out-gassing of contaminants sometimes associated with plastic bodied traps. These are the best moisture traps available for use on carrier gas lines in gas chromatography and GC/MS, as well as other applications where high integrity moisture removal is desired. The glass moisture trap is filled with molecular sieve 13X and incorporates a band of indicating molecular sieve 4A. The refill kit contains sufficient material to refill three 70cc units, two 100cc units or one 250cc model. Each nickel plated Swagelok™ end fitting includes a 40 micron stainless steel frit.
