Chromatography Technology CTS-3109 Syringe 250uL

CTS-3109 is a 250 µL syringe replacement designed to be directly interchangeable with Waters OEM WAT073109 for Waters autosamplers, providing a drop-in part that preserves the original injection volume and interface fit. Compatible with Waters models including 717, 717 Plus, 2690, 2690D, 2695, 2695D, 2790, 2795, and Alliance, it also serves in Waters WISP autosampler configurations as a standard replacement component for maintaining accurate peak integration across injections. Wetted components are borosilicate glass and PTFE, with the syringe assembly designed to OEM tolerances to minimize variability in sample uptake and injection; some listings also reference 316 stainless steel in non-wetted parts, aligning with common HPLC syringe construction. Marketed by Sciencix as CTS-3109 and listed as equivalent to Waters WAT073109, the part is shown in catalogs and maintenance kits such as the 2690/2695 Performance Maintenance Kit (CTS-11380) and other Waters-compatible parts listings. Used for routine maintenance and replacement on eligible Waters systems, the CTS-3109 250 µL syringe helps sustain reliable injection volumes and reproducibility without requiring OEM-only parts.
