A range of accessories and other equipment for thermal analysis.
When working under vacuum with thermogravimetric analysers (TGA), it is important that the vacuum is both applied and released slowly, otherwise the sample or sample pans can be blown around inside the TGA and cause contamination which requires cleaning out. Ruston Services has designed a suitable manual control panel such that the vacuum can be applied and released using needle valves, with a vacuum gauge which gives a clear indication of the line pressure to the TGA at all times.
The design of the gas system is such that the TGA can be let up to ambient pressure from a nitrogen supply to ensure that the sample is not exposed to oxygen, or the system can be let up to air.
Vacuum gauge always shows the pressure in the TGA Line. Needle valve to control gas inlet speed to return the TGA system to ambient pressure Needle valve to control evacuation rate and avoid disturbing the sample or the TGA balance On/off toggle valve to isolate vacuum pump from the control panel TGA can be returned to ambient pressure using a nitrogen purge inletA suitable vacuum pump can be supplied at extra cost. Please state voltage required.

| Vacuum Hose | 6m of silicone vacuum hose (11mm OD x 6mm ID) is supplied with the control panel |
