With the first 24-sample v a c u u m manifold that s n a p s from w a s t e p o s i t i o n t o collect w i t h o u t o p e n i n g . The Adsorbex" vacuum manifold has two operating positions t h a t let you move from waste steps to collect steps with hardly a pause. So with its 24-sample capacity, you can prepare more samples, faster t h a n ever before. And you can do it with these unique conveniences: • Glass sides. Makes it easy to monitor and troubleshoot the sampling process ( I • Removable, replaceable solvent guides made from medicalgrade polypropylene. Makes it a snap— snap on, snap off—to ensure contaminationfree samples. • Built-in pressure regulator. Makes sampleto-sample consist ency a certainty—at no extra cost. With c o l u m n s that s n a p together without adapters. The patented design of Adsorbex columns includes
phase, and ion exchange types. • Reverse phase Adsorbex sorbents are end-capped—residual silanol groups are bonded for optimum selectivity.
unique taper-lock fittings t h a t make connections and mode sequencing quick and easy, also eliminating additional sources of sample contamination. But there's more snap to it t h a n that: I Î I · The wide mouth fe^^ makes Adsorbex columns easier, faster, and neater to load. The formed rim is ideal for the grippers on robotic sample prep systems. There's more purity, too: • Columns are made from medicalgrade polypropylene to eliminate interference from plasticizers. A wide range of bonded silica sorbents is available, including normal phase, reverse
