微孔聚丙烯透气膜 | 325

产品特点：

微孔聚丙烯透气膜 （Microporous Polypropylene Gas Permeable Film）

微孔膜是一种气体渗透膜，用于分析氦冲洗或真空中不挥发的液体和粉末状样品物质。在保持紧绷的薄膜样品支撑平面的同时，平衡样品杯和样品腔内的压差。1500系列XRF样品杯适用于微孔薄膜。

● Equalizes pressure differentials within sample cups and sample chamber

● Maintains uniform target-to-sample distances

特点：

● 均衡样品杯和样品腔内的压差

● 保持平坦的薄膜样品支撑窗平面

● 保持目标到样品的均匀距离

One of two supplied "Snap-On Rings" included with the 1500 Series Sample Cups is used to attach Microporous Film to the Cell neck of the open end of the sample cup nearest the outer integrated flange.

1500系列样品杯随附的两个“卡扣环”之一用于将微孔膜附着到样品杯开口端最靠近外部集成法兰的样品池颈部。

The sample cup Cell is designed with the unique "bead-to-indent" geometry that creates taut thin-film sample support planes and effective seals against leakage.

样品杯池的设计具有独特的“珠到凹痕”几何形状，可形成绷紧的薄膜样品支撑平面并有效密封以防泄漏。

The second included "Snap-On Ring" is used to affix a thin-film sample support window to the opposite open end of the sample cup.

随附的第二个“卡扣环”用于将薄膜样品支撑窗固定到样品杯的相对开口端。

In practice, the illustrated assembly procedure is reversed. The thin-film sample support is attached first enabling one or more sample cups to be conveniently filled from the top end; Microporous Film is attached last.

实际上，图示的组装过程是相反的。首先连接薄膜样品支架，以便从顶端方便地装满一个或多个样品杯。最后附上微孔膜。

Microporous Film is also available in Easy-to-Use Precut Circles for elimination of trimming and convenience of attachment to Chemplex® XRF Sample Cups.

微孔膜是易于使用预制圈子消除修剪和附件的便利Chemplex® XRF样品杯。
