Poncho Safety Shield for Series TM or STM Heating Mantles

Item #: 20190
Quantity:
$178.00

Availability: 4-5 business days

Product Description

The Glas-Col 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 (see item #'s 20160-20183) 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. (Nitrogen is not recommended because of possible damage to mantle heating elements.)

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 rugged silicone sealer ring to provide an airtight fit and an NPT purge relief port (1/8" for sizes 5,000 mL and smaller and 3/4" for the others). The 22 liter model is shown in these pictures. The shield comes with an accessory kit to provide robust connection to the mantle.

Ponchos are designed for single-neck flasks and are shipped ready for use. Ponchos for flasks with modified or additional necks are available on a custom basis.
