一般描述

Visiprep DL（一次性连接管）真空固相萃取装置消除了在同一端口处理新样品时发生交叉污染的风险。该一次性连接管一端是聚丙烯内螺纹luer 接口可以直接连到 SPE 小柱上，另一端 PTFE 细管可以通过 SPE 装置的端口。这可确保与样品接触的所有固相萃取端口和控制阀的表面可在每次萃取后得到更换。
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真空歧管用于进行固相萃取仪将多酚从葡萄中进行分离，从而能够通过LC-MS分析对多酚的含量进行确定。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。此外，它还用于通过固相萃取-酶联免疫吸附测定（SPE-ELISA）对水中的雌酮进行萃取和测定。

特点和优势

按100只一次性衬垫（货号57059）进行提供。
  • 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。
