Asynt has collaborated with the chemists and engineers at The University of Nottingham, to bring their expertise and respect for the safety aspects of working at high pressure in the laboratory to the general market in the form of PressureSyn, a new High Pressure reactor with safety built in.
The new MKII 125 ml PressureSyn reactor is now certificated and tested to provide a maximum working pressure of 180 bar and temperature of 200 °C. The easy to open clamp mechanism also features a unique Safety Key designed by the chemists and engineers at Nottingham that does not allow the vessel cover to be removed without first releasing any residual pressure. Each Safety Key and vessel clamp are unique therefore ensuring that it cannot be undone with a spare key, only the Safety Key that is used to release any residual pressure of the reactor in use will open the clamp. Even with an operator opening the standard pressure relief valve in the correct manner it is possible to have a small blockage in a valve leading to some residual pressure. This required a safety design feature to be developed for the reactors to ensure that this was not possible; therefore each Safety Key valve assembly has a pin at its tip ensuring that when extracted will leave behind a small hole for any residual pressure to be released.
Each individual reactor is witness tested to 331 bar.g for 30 minutes, and certificated at this pressure by Zurich Insurance, giving our customers secure knowledge that this reactor when in use at its maximum it is actually very under stressed.
The standard safety features of PressureSyn comprise a double pressure relief system, including bursting disk and pressure relief valve.
PressureSyn units are designed to work on any magnetic hotplate stirrer; a special DrySyn adapter plate allows the secure placement of the reactors on the hotplate stirrer; together with enhanced temperature transfer and the ability to control temperature from a standard hotplate stirrer’s temperature probe.
