WHATMAN析相纸 1PS相分离滤纸液相分离滤纸 1PSFILTER WHATMAN 选购信息 编号 233401 直径mm 70 分离量 10 包装 1盒（100枚入） 价格 元 216 23340290151盒（100枚入）312233403110201盒（100枚入）446233404125351盒（100枚入）507.00233405150751盒（100枚入）693.002334061851351盒（100枚入）1089.002334072403001盒（100枚入）1628.00 性能特点 ●沃特曼1PS析相纸是一种疏水性的高级滤纸，它可以自动截流，保留水相并让溶剂相通过。同时除去液相中的沉淀物。 使用事项 ●将混合相摇晃后，倒入装有1PS滤纸的漏斗内。它的分离速度相当快，只需一会儿时间，液滴便白动分开，溶剂相完全脱离水相。 ●无需监控、操作简单灵活：使用1PS析相纸一个主要的优点是，当溶剂相完全滤过时，分离也就立刻自动停止了，操作者无需特别经验； ●同时多个分离可一起进行。 The Whatman 1PS Phase Separator is a high- grade filter paper impregnated with a stabilized silicone that renders it hydrophobic, retaining the aqueous phase and passing the solvent phase through. Features and Benefits Ease of use – no special training required Any number of separations can be processed together Staff involvement in routine separations is at a minimum Automatic Cut-Off, Separatory Funnel Replacement After being shaken, the mixed phases are simply poured directly into the 1PS circle which is quadrant-folded in a funnel. The separation is extremely rapid so it is unnecessary to wait until the two phases have settled into separate layers. Droplets are automatically separated after only a few moments, giving a solvent phase completely free of the aqueous phase. In many applications, 1PS can replace the use of separatory funnels. The solvent phase flows through the paper quickly and cleanly. It then stops automatically, leaving the aqueous phase completely in the paper. This feature is particularly important when carrying out a large number of routine solvent extractions at the same time. Samples can be shaken with solvent in stoppered conical flasks or test tubes and transferred directly to funnels containing 1PS. Unsupervised Separation A chief benefit of the 1PS method is that cut-off is automatic and complete just as soon as the solvent phase has passed through*. The result is no skilled operators are required. 加工定制 否 定量 xx（g/m） 尺寸 70-240（mm） 包装说明 1盒100只 颜色 白 用途 混合液体分离
