How to remove and replace DiffLok cap O-rings
DiffLok™ (diffusion-locking) 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.
DiffLok caps:
- Preserve sample integrity by preventing analyte loss and contamination
- Ensure reproducible results during analysis
