一般描述

SPE是一种层析方式,就像其他层析技术一样,控制流率是保持可重复提取的关键。不像其他的真空装备,Visprep系统含有具有专利的阀系统,使用旋转的,独立的,螺旋型的阀们,能够对经过每一个SPE管的流量精准控制。阀们安装在装备的每一个端口上。Visprep真空装备使你能够一次同时处理12(12端口版本)或24(24端口版本)个SPE样本。24端口版本的每个端口间距离比12端口版要小,所以建议购买前考虑好管子大小。

应用

Visiprep SPE真空装备用于进行固相萃取,从葡萄中分离多酚类物质,从而使用LC-MS分析法确定多酚类含量。它还用于浓缩和净化地表水和污水沉积物中的溶剂萃取物。另外,它还被用来提取和确定水中的雌激素酮。使用的是固相提取物-酶-连接免疫吸附分析(SPE-ELISA)。

特点和优势

  • 固相萃取端口中专利的螺旋式阀门用于精确的流量控制
  • 玻璃槽接触到溶剂时不会溶解、变模糊或褪色
  • 盖上带有支脚,当使用者将盖从固相萃取装置上取下时,可方便地放在工作台上
  • 螺旋式耐溶剂真空表和减压阀提供更好的密封和真空控制。阀门可与 1/4″ 英寸真空管连接。
  • PP 收集容器架可容纳自动进样器样品瓶;小型闪烁样品瓶(推荐 22.75mm 外径);10 和 16mm 试管;以及 1、2、5 和 10mL 容量瓶。可为 12 端口的型号选配用于 20mL 闪烁样品瓶的板。
