• intros：{"brand_intro":"北京中镜科仪技术有限公司成立于2005年，是国内电镜与病理耗材领域的知名供应商。公司早期以代理进口品牌起家，2015年起自主研发包埋树脂。其技术团队与北京理工大学合作，开发出低毒性GMA单体合成工艺。中镜科仪以\"实用、耐用、实惠\"为品控理念，产品主要面向高校教学与基层医院。虽然品牌知名度不及进口大牌，但在国内性价比市场占有重要地位。","product_intro":"ZJ-JB4-500 是中镜科仪推出的经济型JB-4树脂，主打大容量包装（500ml单体+配套催化剂）。核心卖点：单次实验成本低至80元，适合教学与大批量样本处理；毒性较低（单体气味小），操作更安全；聚合后切片质量可满足常规HE染色与免疫组化。适用于本科生实验课、临床病理科日常诊断。与进口产品相比，切片厚度下限较高（1.5μm），且抗原保存时间较短（建议3天内染色）。","key_specs":{"单体类型":"低毒性GMA","聚合温度":"0℃至4℃","切片厚度":"1.5-5μm","适用样本":"脱钙骨、软组织、植物组织","保存条件":"4℃避光","保质期":"9个月"}}
