Direct Adaptive HPLC Column Connector, single end fitting with 0.005" ID x 1/16th" OD, 200 mm long stainless steel tubing. MICROSOLV Brand. 1 EA.
Additional Info:
The 49905‑20‑SD Direct Adaptive (Di‑Ad™) HPLC Column Connector is designed to provide a reliable, low dead volume connection between HPLC system components and analytical columns without requiring repeated ferrule adjustments when changing column brands.
This single‑end fitting assembly includes precision laser‑cut 0.005" (127 µm) ID stainless steel tubing with a 1/16" OD and 200 mm (7.87") length for optimized chromatographic performance and reduced extra‑column dispersion.
The spring‑loaded Di‑Ad™ fitting automatically adjusts tubing pilot length during installation, helping ensure a tight seal with minimal void volume across different HPLC column inlet and outlet geometries. This self‑adjusting design reduces the need to manually reposition ferrules or re‑swage tubing during column replacement procedures.
These connectors are commonly installed between the injector and column inlet as well as between the detector and column outlet to help minimize system volume induced band broadening and maintain chromatographic efficiency.
The 49905‑20‑SD connector is especially useful in laboratories that routinely switch between different HPLC column brands while requiring consistent low dispersion performance and simplified operation.
