MultiScreen 打孔装置包括打孔手柄、滑动打孔底座、打孔分配器，以及 8 位样品底座支架。
MultiScreen 打孔装置包括打孔手柄、滑动打孔底座、打孔分配器，以及 8 位样品底座支架。
完成分析之后，可使用打孔装置和一次性打孔针同时取下 MultiScreen 滤膜板的 8 个孔中的滤膜，并将其分配到 8 个闪烁瓶中，用于闪烁或 γ 放射性检测。
拥有专利设计的打孔针可单独取下每个孔的膜，从而避免了交叉污染并提高了重现性。

| Which MultiScreen membranes can be punched out of the plate using the MultiScreen Punch Kit? | All plates containing the Durapore (PVDF) membrane can be punched. Mixed cellulose ester membranes (HA) and glass fiber membranes must be wet when punched from the plate. When punching glass fiber, some of the underlying Durapore disks may be left behind, but 99% of the counts will be on the glass fiber disks. The ion exchange membranes (DE and PH) and the PTFE membranes (R1, R4) cannot be punched. |
| Will the MultiScreen disposable punch tips quench a radioactive signal when counting? | No, the punch tips shouldn't interfere with counting. It may be necessary to add bleach to punched discs to release counts when weak beta emitters are used (e. g. 3H and 14C). |
| Can I decontaminate the MultiScreen punch hardware and accessories of radioactivity? | Yes. The punch mechanism should not require decontamination since it never directly contacts the membrane. Accessories can be decontaminated with normal non-organic solvent solutions or sprays designed for this purpose. |
