Inventors include Jeyavishnu K; and Manish Malhan.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: ABSTRACT Adjustable photometric Vial System with a Silicone Rubber Valve for Controlled Sample Dispensing The colorimetric vial system is designed to improve sample dispensing accuracy and efficiency in field-level testing. It features a transparent glass vial [101] that holds the sample liquid, with a silicone rubber cap [102] that prevents contamination, evaporation, or spillage. The cap integrates a one-way valve mechanism [104] to secure the sample until dispensing. The system includes an upper compartment [103] in the cap, allowing pre-loading of the sample to reduce contamination risks. The adjustable headspace [105] enables precise control over the volume of liquid held before dispensing by modifying the height between the valve [104] and compartment [103]. The system’s design includes a movable mechanism [106] within the cap [102] for accurate volume control and ensures no overflow [110] by managing liquid dispensing. The self-sealing cap [102] ensures accuracy and prevents contamination after dispensing. This versatile system accommodates varying sample volumes, making it suitable for diverse testing applications while reducing errors in traditional manual methods.
