CHROMATOGRAPHY VIALS & SEPTAS & CAPS

septas & caps

• Sealing units for vials are combination of caps and septas. Caps can be offered either with slit or without slit.
• For problem-free and correct results seals scould also be inert and uncontaminated.
• Almost all septa are laminated on one side with PTFE, which has a high chemical resistance and forms an inert barrier between the sample in the vial and the cap of the septa.
