• intros：{"brand_intro":"CNW是上海安谱实验科技股份有限公司旗下的国产耗材品牌，成立于1997年，专注于实验室耗材与标准品。安谱创始人夏敏勇以'让中国实验室用上高品质国产耗材'为使命，逐步建立起从研发到生产的完整体系。CNW样品瓶采用国产高硼硅玻璃，经ISO 9001认证工厂生产，品控对标国际品牌。凭借高性价比和快速物流，CNW已成为国内高校和中小企业的首选品牌，市场份额逐年攀升。","product_intro":"这款经济型2mL透明螺口样品瓶是CNW的走量爆款，主打'好用不贵'。核心卖点：价格仅为进口品牌的1/3；瓶盖隔垫采用PTFE/硅胶复合材质，密封性可靠；瓶身带磨砂书写区。与安捷伦相比，其玻璃内表面惰性稍弱，但日常GC分析（如溶剂残留、农药残留）完全胜任。适用于教学实验室、常规质控及预算有限的研发团队。","key_specs":{"容量":"2mL","材质":"高硼硅玻璃（国产）","瓶口类型":"9mm螺口（带隔垫）","适配性":"兼容主流自动进样器（安捷伦/岛津等）","包装规格":"100个/盒"}}
