• intros：{"brand_intro":"大龙仪器（DLAB）成立于2004年，总部北京，是中国实验室仪器领域的\"隐形冠军\"。创始人张磊原为北大生物系研究员，因不满进口设备高价而创业。大龙以\"高性价比替代进口\"为使命，核心优势在于自主研发的步进电机控制算法和模块化设计。品控上，大龙通过ISO 13485医疗级认证，每台设备出厂前需通过100次连续启停测试。目前产品出口60余国，是国产实验室仪器的\"价格屠夫\"。","product_intro":"MX-S是大龙最畅销的入门级可调式混匀仪，定位\"实验室第一台振荡器\"。核心卖点：0-3000rpm可调、4mm圆周振幅、防滑硅胶垫+试管夹具双模式，以及超静音设计（<50dB）。适用于教学实验室、小型药企的日常混匀，如溶液配制、细胞重悬等。相比进口品牌，MX-S价格仅为1/5，且提供3年质保；但振幅精度和电机寿命略逊于IKA。","key_specs":{"振幅":"4mm（圆周运动）","转速范围":"0-3000 rpm（旋钮调节，精度±5%）","最大承载":"0.4 kg","电机类型":"直流电机（碳刷，寿命约5000小时）","噪音":"≤50 dB（A）","适用容器":"试管、离心管、96孔板"}}
