Title: Innovations by Henry D Schwartz

Introduction

Henry D Schwartz is a notable inventor based in Palo Alto, CA (US). He has made significant contributions to the field of fluid metering and liquid handling, holding a total of 8 patents. His innovative designs have improved the efficiency and precision of fluid dispensing mechanisms.

Latest Patents

Among his latest patents, Schwartz has developed the "Dual Differential Displacement Fluid Metering." This invention enhances the aspiration and dispensing of fluids through a unique mechanism. It features an offset diameter of a bottom tube with a narrower top piston, allowing for extremely fine resolution. This design eliminates the need for skinny or filamentous pistons. Additionally, it permits the bottom tube to move independently in the chamber for high flow rates. The mechanism also includes a space for contact-free blowoff, accommodating viscous samples, and is equipped with an adjustable knob and readable volume gauge for handheld operation.

Another significant patent is the "Dual Resolution Liquid Handling." This invention also improves liquid aspiration and dispensing. It utilizes a tapered top piston with an offset diameter bottom tube to achieve fine resolution. The use of thick-walled compliant O-rings enhances the sealing against the different diameters of the tapered piston, providing an additional range of resolution. Similar to his previous invention, it allows for high flow rates and contact-free blowoff.
