雨披安全盾牌
雨披安全罩在系列TM或STM罩上覆蓋一個燒瓶，極大地提高了操作安全性。易燃液體只有在雨披安全罩被使用時，才會在系列STM mantles中進行處理，而且，在12升和更大的尺寸中，可以用氬氣等惰性氣體凈化地幔和雨披。除了減少火災(zāi)隱患，雨披護罩還可以保護燒瓶，防止像螺絲起子或鉗子之類的掉落物，保護人員免受飛行玻璃的傷害
如果燒瓶在高真空蒸餾或爆炸下內(nèi)爆，并作為一種有效的絕緣體。雨披有兩個玻璃觀察端口，允許在仍提供保護的情況下加熱材料。盾牌裝備有一個密封圈和一個不擴散端口(1 / 8大小的P1300和更小的和3 / 4英寸的P1400和更大的)。圖中顯示的Ponchos是單頸瓶，并已準備好供使用。多頸瓶的Ponchos可能要求在實驗室進行zui終的擬合。
請注意
當使用額外或改良的頸瓶時，頸位置和管狀長度是重要的。為了減少擬合問題，側(cè)頸不應(yīng)低于赤道和上中心頸之間的距離。如果可能的話，側(cè)脖子應(yīng)該是垂直的，并且脖子必須通過雨披來完成，這樣才能使錐形或球狀關(guān)節(jié)的形成(見圖)。對于較大尺寸的，請咨詢工廠。

PONCHO SAFETY SHIELDS
The Poncho Safety Shield covers a flask in a Series TM or STM mantle, greatly improving operating safety. Flammable liquids should be processed in Series STM mantles only if a Poncho Safety Shield is used and, in sizes 12-liter and larger, the mantle and Poncho can be purged with an inert gas such as argon. In addition to reducing fire hazards, the Poncho Shield also protects flasks from falling objects such as screwdrivers or pliers, protects personnel from flying glass and
liquid if flask implodes under high vacuum distillation or explodes, and serves as an efficient insulator. The Poncho has two glass observation ports, allowing the material being heated to be seen while still affording protection. The shield is furnished with a sealer ring and an NPT purge relief port (1/8 for sizes P1300 and smaller and 3/4” for P1400 and larger).Ponchos shown in chart are for single-neck flasks and are shipped ready for use.Ponchos for multiple-neck flasks may require final fitting in lab.
Note
When using flasks with additional or modified necks, neck location and tubulation length are important. To reduce fitting problems, side necks should not be lower than halfway between equator and top center neck. Side necks should be nearly vertical, if possible, and necks must project through Poncho far enough to allow makeup of taper or ball joints (see chart). For larger sizes, please consult the factory.
