    1. 样品数量:可同时浓缩处理1~12个样品;
    2. 浓缩瓶容积:50ml150ml200ml
    3. 终点检测:每一个工作通道均配有专门的光学化干器,自动、独立地检测终点,无需人工看管;

    4、终点体积:自动感应的定容体积人别为1.0ml0.5ml或近干(约0.1ml),适当延长时间亦可将溶剂吹干,)不同规格的浓缩瓶可以同时交叉使用;

    5、工作参数任意设置、控制和实时显示:主要工作参数,水浴温度、氮吹时间和气体压力;

    6、水浴温度:室温~95℃(±0.5℃);

    7、氮吹时间:0~9999sec

    8、气体压力:氮吹工作吹扫气压,0~0.10mpa范围内十级任意设定(压力间隔变化为0.01mpa),仪器自带自动调压装置,可自动调节至所设定的吹扫压力并保持恒定,不受工作通道(样品)突然开启、关闭或数量的影响;外接氮气压力(氮气钢瓶分压表压力)范围:0.20~0.80mpa;外接极限气体压力:1.00mpa

    9、气体消耗量:大吹扫压力(0.10mpa)下,每通道约500ml/min(约17cfm);

    10、定容灵敏度:十级可调,保证不同颜色或透光度的溶剂的浓缩定容更为准确;

    11、控制方式:用户可根据实际情况,自行选用手动方式或智能方式控制吹扫终点;

    12、报警提示:仪器在开盖、浓缩完成、水浴水量或氮气压力不足时,均会自动报警提示;

    13、仪器运行中途开盖,自动智能记忆工作状态及通道60秒,60秒内合上盖子,仪器继续执行之前被中止的程序,无需重新设置工作参数及工作通道;

    14、所有橡胶配件均采用无增塑剂的硅胶制造,输气管路采用食品级特氟龙管,避免样品收到来自仪器的污染;

    15、灵活的工作参数设定、方便的样品置入/取出过程,免去繁琐的准备工作,减低了有机溶剂对操作人员的毒害;

    16、密闭式结构设计及自带的强力排风系统可将有机挥发成份和水蒸气集体统一排出,避免了有机溶剂在实验操作空间的挥发扩散,极大地保障了操作人员的身体健康,并避免了对坏境的污染;

    17、仪器没有排水装置,极大地方便了用户更换加热用水;
