High-pressure laboratory autoclaves model II Accessories for gas injection

From  Carl ROTH


200/300 ml/100 bar, 250 ml/200 barModel II encompasses devices for all reactions where spontaneous gas development and a quick increase in pressure are to be expected. The devices are operated with a large bursting disc, that is incorporated in the autoclave head. They thus offer maximum operational safety. The enlarged autoclave head is screwed directly onto the cylindrical autoclave beaker. It contains the bursting disc holder at the top and three threaded openings at the side. For connections with: valves, reducers for pressure gauges and temperature sensors or burst disc safety device ll (when using magnetic stirrer head MRK 10).Threaded openings can be closed with screw stoppers. Sealed with PTFE gaskets (max. 180 °C) or pure silver gaskets (max. 300 °C).Depending on the scope of the autoclave system, delivery times may apply!

Attention

Due to the shape of the screw thread, cold setting of cylinder and head is possible when screwing these on. This usually leads to them sticking when opening and the thread breaking as a result.The conducted reaction necessitates coating the thread with a release agent such as PTFE spray (Art. No. K007.1).Warning: Do not use PTFE screw thread tape!


Advice for working with silver gaskets

When working with silver gaskets, it is essential to tighten the screw threads very tightly to achieve the necessary seat. We therefore recommend annealing the silver gaskets at +850 °C before use - the gaskets remain softer and more pliable, even when cool, and seal more efficiently.
