DiffLok Caps, One Stainless-Steel and One Inert, 1/4″ (10 pair pack)

DiffLok caps (Diffusion-Locking). One stainless steel, one inert, 1/4 “, pk 10 pairs. DiffLok™ caps sit on both ends of a sorbent tube throughout the entire analytical sequence, in all Markes’ automated thermal desorption instruments. Their patented design prevents loss of sample and ingress of contaminants onto the tube, and avoids the need for complex robotics to cap and uncap tubes. DiffLok caps are available in stainless and inert-coated stainless steel.
