• intros：{"brand_intro":"瑞宁（Rainin）是美国梅特勒-托利多集团旗下的实验室液体处理品牌，1963年由工程师John Rainin创立，以\"精准移液\"闻名。其超滤产品线虽非核心，但凭借\"低吸附吸头\"技术切入市场，主打微量样品处理。品牌强调\"人体工学\"与\"数据完整性\"，所有产品均通过ISO 8655认证。在中国，瑞宁吸头被高端实验室视为\"移液器伴侣\"，品控理念为\"零误差\"，每批次均提供COA证书。","product_intro":"Ultra-Low Binding 超滤吸头专为\"痕量样品\"设计，采用专利的\"氟化表面\"技术，对蛋白质、核酸的吸附率<0.1%。核心卖点在于其\"无滤芯\"结构，避免传统滤芯带来的死体积问题。适用场景包括qPCR、NGS文库构建及单细胞转录组学。与竞品相比，其最大优势是\"即插即用\"，无需预湿处理，且兼容所有主流移液器。","key_specs":{"容量范围":"10 μL - 1000 μL","材质":"聚丙烯 + 氟化涂层","吸附率":"<0.1%（BSA测试）","适配性":"兼容Eppendorf、Gilson、瑞宁等移液器","灭菌方式":"伽马射线灭菌","包装规格":"96支/盒"}}
