WRPS Sampling and Transportation Tool

Abstract

During FY24, PNNL developed a tool to assist in the sampling and transportation of liquid samples. The tool was designed to remotely open and close a glass jar while fitting inside a 3-inch inner diameter pipe. It was also designed to be reusable, with as few single-use parts as possible to reduce machining costs. The final design consisted of a stepper motor with a linear action, a sleeve that attached to the stepper motor, a lid body that threads onto the glass jar, and a sealing lid that is opened and closed via the stepper motor. Secondary components included O-rings, screws, and a wave spring that keeps the lid pressed into place after the stepper motor is disconnected.
