These C-line syringes feature a direct attachment design of the needle to the barrel which eliminates contact between the sample solvent and adhesive, reducing carryover and ghost peaks. The inert plunger tip polymer provides enhanced solvent compatibility and longer lifetime.

Supplier: COLLECTION PREFIX HPLC

On-Line degassing has been shown to be more effective at removing dissolved gas from mobile phases than sonication or helium sparging. Up to five solvent lines can be degassed simultaneously by one unit. The extremely low volume of each PTFE AF channel (480 μl) offers very quick equilibration and very short start-up times.
