Abstract: ABSTRACT Photometric Vial System with Inert Tube for Reagent/sample Isolation and Dispensing The invention provides a photometric vial system for field-level testing, comprising a transparent glass vial [100] that holds a sample liquid and an integrated inert tube [101] to store reagents separately. The inert tube is made from chemically inert materials like high-grade plastic, glass, or polymer, ensuring no chemical interaction with the sample liquid or reagents. An internal protrusion [103] securely holds the inert tube [101], preventing accidental movement and contamination until the reagent is dispensed. The system also includes a screw-type mechanism [102] that allows precise control over the dispensing of reagents, enabling the user to extend or retract the inert tube as needed. Additionally, the system accommodates varying diameters [104] of the inert tube, providing flexibility for different sample volumes and testing applications.
