The Types segment classifies kits according to the underlying purification technology, with five major groups: column‑based chromatography, magnetic‑bead affinity, pre‑packed filter systems, affinity‑membrane chromatography, and ultracentrifugation kits. Column‑based kits dominate the market, offering reproducible resin interactions and supporting a broad range of virus families, which translates into the highest revenue contribution. Magnetic‑bead kits provide rapid, low‑volume processing and are favored for high‑throughput screening, representing a growing niche. Pre‑packed filter systems, valued for their simplicity and low equipment requirements, serve laboratories with limited infrastructure. Affinity‑membrane kits combine high binding capacity with short processing times, appealing to both research and production settings. Ultracentrifugation kits, while less common due to equipment costs, remain essential for applications demanding ultra‑high purity, such as gene‑therapy vector preparation. Each type’s market share reflects its technical advantages, cost structure, and alignment with specific application needs, shaping the overall market composition.
