Material: stainless steel 1.4571 (V4A). 200/300 ml/100 bar, 250 ml/200 bar Model 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!
