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.
