DiffLok caps contain a long/narrow helical flow path, which slows the rate of diffusion to a point where it becomes negligible. However, once pressure is applied in the analytical system (or via a pump), the tube performs as an uncapped tube.
DiffLok caps are available for industry-standard tubes (ID 1/4 inch) and 4½ inch DAAMS tubes (ID 6mm).
When working with inert tubes, only one inert cap is required on the sampling end of the tube; the other end can be stainless steel, as it is not in the flow path of the sample. Replacement O-rings are available for routine maintenance.
40 caps (20 stainless steel and 20 inert-coated stainless steel) ship with each automated instrument from Markes.
DiffLok caps are also used with an MTS-32 (multi-tube sequencer) to prevent loss of sample, ingress of contaminants and diffusive effects when undertaking low-flow sampling. For less experienced users, they can also be used in combination with SafeLok inserts in place of long-term storage caps.
