Princeton Separations Scientific

Princeton Separations Scientific is a long-standing, private biotechnology firm focused on manufacturing high-quality molecular separation consumables for the life science research market. The company's core technology platform revolves around spin-column-based purification (Centri-Sep, Centri-Spin) and a newer electrophoretic recovery system (Electro-Sep/Gene Stix) for DNA/RNA size selection, primarily serving Sanger and Next-Generation Sequencing workflows. As a small, specialized manufacturer celebrating its 40th anniversary, it competes by offering reliable, 'Made in the USA' products and has established credibility through adoption by major sequencing protocol developers and government labs. Its future growth is tied to expanding its novel Gene Stix technology and leveraging distribution partnerships.

Platform based on size-exclusion chromatography spin columns (Centri-Sep, Centri-Spin) and electrophoretic DNA/RNA recovery from gels (Electro-Sep/Gene Stix) for molecular separations in genomics research.

PSS competes in the research consumables space against giants like Thermo Fisher Scientific, Agilent, and Qiagen, which offer broad portfolios and global reach. It differentiates through specialized, high-quality 'Made in USA' products, deep expertise in spin-column purification, and a novel electrophoretic recovery technology not widely offered by competitors.
