Direct Adaptive HPLC Column Connector, double end fitting with 0.005" ID x 1/16th" OD, 200 mm long stainless steel tubing. MICROSOLV Brand. 1 EA.
Additional Info:
Direct Adaptive (Di‑Ad™) HPLC Column Connectors are designed to provide reliable, low dead volume connections between HPLC system components and analytical columns without requiring repeated ferrule adjustments when changing column brands.
The 49905‑20‑DD connector 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.
This double‑end fitting delivers a near zero dead volume connection to virtually any brand of HPLC column, helping minimize system volume induced band broadening for improved chromatographic efficiency while making column changes easier and more convenient between runs.
The spring‑loaded Di‑Ad™ fittings automatically adjust 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 eliminates the need to repeatedly reposition ferrules or re‑swage tubing each time a different column brand is installed.
These connectors are commonly installed between the injector and the column inlet as well as between the detector and the outlet side of the column to help maintain system efficiency and reduce extra‑column effects.
The double‑ended Di‑Ad™ design is especially useful in laboratories that routinely switch between different HPLC column brands while requiring consistent low dispersion performance and simplified operation.
