About RPI

RPI (Research Products International) is a manufacturer of laboratory chemicals and biochemicals, headquartered in the United States. The brand supplies a broad catalog of reagents, buffers, detergents, and specialty compounds used in molecular biology, biochemistry, and cell culture applications. 3G Electric distributes select RPI products globally, focusing on protease inhibitors and related lab-grade chemicals. The product line includes proteinase K (available in 100 mg and 500 mg powder formats), 5-fluoroorotic acid (5-FOA), polyoxyethylenesorbitan monooleate (Tween 80), polyoxyethylenesorbitan monolaurate (Tween 20), Nonidet P-40 substitute, FUDR (5-fluoro-2-deoxyuridine), and glycerol. These items are supplied in lab-grade or USP-grade purity, with BSE/TSE-free options on several SKUs. Container materials are plastic or glass, depending on the product. RPI chemicals are formulated for reproducible results in research and industrial labs, with specifications such as form (powder or liquid), volume, and container type clearly stated on each datasheet. 3G Electric supports the line by offering multiple SKUs with detailed product information, enabling procurement specialists and lab managers to select the correct grade and packaging for their workflows. Logistics support includes global shipping and access to technical datasheets for each item. The range covers common lab reagents used in protein extraction, nucleic acid purification, cell lysis, and buffer preparation. For buyers requiring consistent supply of standard biochemicals, RPI products distributed by 3G Electric provide a reliable source with documented purity and handling guidelines.
