Pro Clean™ Screw cap with Seals
Zodiac provide high quality screw caps (Pro Clean) for wide opening (9mm) vials. All caps are designed and packed in a clean environment that reduces contamination. High quality screw caps provide the excellent autosampler handling performance.
Pro Clean septa offers Low bleed, Excellent resealability, Resists coring, High puncture tolerance. These are available in a range of materials including silicone rubber, PTFE, and butyl rubber. These septa ensure a good resealability even after repeated punctures. PTFE/Silicone septa are ideal for most HPLC and GC applications where resealability and purity are critical.
To avoid the blockage in the connecting tubing and sample contamination by the unwanted fragments of material produced by seal damage caused due to piercing by the needle during sampling, a choice of Pre-Slit septa could prove a best result in maintaining purity. A Slit through the center of the septum is provided for easier needle penetration.
Pre-slit septa are highly recommended for Shimadzu , Hitachi, and other autosamplers with thin gauge needles.
