美國Glas-Col鋁制加熱套保護罩/防護罩PONCHO SAFETY SHIELDS

雨披安全盾牌

Poncho安全罩在系列TM或STM地幔中覆蓋了一個燒瓶，大大提高了操作安全性。只有在使用了Poncho安全盾牌，并且在12升和更大的尺寸下，可以用惰性氣體(如氬氣)凈化斗篷和斗篷，才能在系列STM mantles中處理易燃液體。除了減少火災危險，雨披護盾還可以保護燒瓶免受諸如螺絲刀或鉗子之類的墜落物體的傷害，保護人員免受飛行玻璃的傷害

液體如果燒瓶在高真空蒸餾或爆炸中內爆，并作為一種有效的絕緣體。Poncho有兩個玻璃觀測端口，允許在仍提供保護的情況下加熱材料。盾牌上有一個密封圈和一個不擴散條約清洗的港口(1 / 8大小的P1300和更小的和3 / 4”的P1400和更大的)。下圖所示的Ponchos是單頸燒瓶，已經準備好使用。多頸燒瓶的Ponchos可能需要在實驗室進行zui后的試穿。

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.

How to order

Specify catalog number in chart for single-neck flasks. Submit a sketch for custom-made flasks or those difficult to describe.
