500 ml/100 barModel IV is the largest autoclave in the ROTH range. It is an enhanced version of the original from which all other models were developed. Model IV consists of a stainless steel beaker with flange. The solid stainless steel lid is screwed onto the flange using eight screws.The autoclave head is intended for a large busting disc as standard. It thus provides enhanced operational safety in the case of spontaneous gas development and a quick increase in pressure.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 bursting disc safety device ll (when using the magnetic stirrer head).Threaded openings can be closed with screw stoppers. Sealed with PTFE gaskets (max. 180 °C) or with pure silver gaskets (max. 300 °C).The beaker and head combination consists of 8 hexagon bolts and nuts for simple assembly.Depending on the scope of the autoclave system, delivery times may apply!
