Vacuum and flow degasser for gas sorption analysis
Six-Port, Vacuum and Flow Degasser for Surface Area and Pore Size Analysis Sample Preparation.
The MasterPrep™ is designed to provide users of the AUTOSORB, QUADRASORB, NOVAtouch and NOVAe Series surface area and pore size analyzers with high throughput sample preparation capabilities. Each of the six sample preparation ports features an independent furnace and digital temperature control allowing many samples to be simultaneously prepared under different conditions. Operating in either flow or vacuum mode, the MasterPrep™ provides the right sample preparation method for any type of material. Flow and evacuation rates are operator selectable. A six-channel digital temperature controller allows for independent temperature programming (up to 20 steps) on each sample preparation port. Programming may be performed via a Windows® PC interface or directly at the controller. Six separate cooling stations hold samples under flow or vacuum conditions after preparation.
• Six sample preparation ports.
• Temperature range: ambient to 425ºC.
• Flow or vacuum degas modes.
• Independent temperature control for each port.
• Back-fill/purge gas user selectable (typically N2 or He).
• Automatic trigger between coarse to fine evacuation rates at user specified pressure to prevent powder elutriation.
• Flow rates independently adjusted for each port up to 100 ml/min.
• Six cooling ports.
• Sample ports accommodate 6, 9 and 12 mm sample cell stem diameters for wide range of samples.
• Digital vacuum gauge.
• CE compliant.
• Independent thermal cut-out switch for each port for over-temperature protection.
