Sapphire window on materials processing
Range of precision-engineered sapphire window optical probes give a new insight on materials during processing
Magna Projects now supplies a range of precision-engineered sapphire-window optical probes in a range of configurations and geometries to allow materials to be studied during processing using techniques such as near infrared (NIR), visible, and UV spectroscopy The optical probes are fitted with a sealed and leak-tested, abrasion-resistant sapphire window and configurations of optical fibres to allow observation by transmission or diffuse reflectance paths

Extended rheometer range
Magna Projects and Instruments has extended its range of MiniCer benchtop capillary extrusion rheometers by introducing the high-speed H-option to allow piston speeds up to 1,500mm/min
A right-angled probe especially designed for injection moulding machine nozzles will pressures up to 2100bar to be monitored, and the straight-pattern Materials Probe permits measurements up to 420C.
Magna can supply custom-built adaptors to allow the probes to be fitted to specific geometries, for example to fit extruders, injection moulding machines, laboratory instruments, reaction vessels, mixers, pipelines, etc.
Additionally, test cells for gas and liquid studies are available.
Use of these probes allows real-time information to be gathered about the actual state of the material as it is being processed, and this information may be used to make rapid and informed decisions about process control.
For example, using near infrared spectroscopy, parameters such as moisture and additive content may be monitored, and relationships to physical properties such as viscosity may be established.
