The COSA Autoclave is based on the the Parr Instruments Series 4530 reactor mounted on a movable cart. 

It is designed to be moveable, allowing for easy relocation. The reactor is equipped with a Grafoil gasket, which allows for operating temperatures up to 600°C. 

This high-temperature capability along with inert gas handling systems makes it particularly suitable for a wide range of experiments, including those involving liquid metals.

The COSA autoclave features a main vessel with a 2-liter capacity and inner dimensions of 4 x 10.5 inches. A head with magnetic coupling enables continuous stirring of the vessel’s contents, and multiple 1/8”NPT and 1/4”NPT ports allow

for the connection of additional accessories. Inert gas, such as Argon, Helium

or other can be used as cover gas to displace atmospheric oxygen and maintain oxygen free environment during the experiment. The autoclave is supplemented with an external melting/filling vessel of 3L volume, which is connected to the main vessel with a heated 1/2“ tube with a high temperature valve. The melting vessel has a pure Iron liner to reduce contamination of the liquid with other metals present in the vessel material. During an experiment, samples of the liquid can be taken using a dedicated liquid sampling system which uses ceramic tubes to prevent contamination of the sample with other metals. The sampling system is designed with particular emphasis on preventing changes of the inner atmosphere during the sampling process.
