Abstract

Microsyringe manipulation is a common approach for the automated sampling of liquids or gases. Commercial devices with this capacity are typically priced above US$30,000, despite their technology being not clearly superior to that commonly found in low-cost (commonly less than US$1,000) devices controlled using G-code (3D printers, CNC routers and laser engravers, for example). Here, we present osmar, an open-source autosampler built by combining parts of two low-cost G-code machines. Movement precision was excellent (error
