VSTAR

Full description

High-resolution vapor sorption analyzer


The VSTAR system goes beyond basic water sorption to provide vapor and gas sorption analyses over a broad range of analysis conditions. Based on the fast and high-resolution vacuum-volumetric gas sorption technique, VSTAR can obtain analysis results in roughly half the time required by classical DVS methods. Wide chemical compatibility allows users to measure adsorption/desorption isotherms and kinetics of many species (organics, alcohols, amines, and more). The VSTAR system comes in two- or four-station versions for any level of throughput the user needs.

Features - Benefits
• Wide Vapor Compatibility:
Organics (saturated, unsaturated, and aromatic), alcohols, amines, water, and more.
• Homogeneous Temperature:
Single thermostatically controlled manifold and vapor source chamber.
• Wide Range of Temperature:
Selectable manifold and vapor source temperature from 40°C to 110°C.
• Flexible Modular Throughput:
Choose either 2 stations for routine work or 4 stations for high throughput labs.
• Independent Sample Temperature:
Each sample station can be maintained at a different temperature (requires multiple circulator baths) or run at a common temperature (sharing a single circulator bath).
• Wide Temperature Range:
Standard circulator controls the sample temperature from –20°C to 100°C with a stability of ±0.01°C *.
• Small Thermal Gradients:
Small volume of sample jackets reduces thermal gradients, even when sharing a single circulator for four stations.
• Reduced Void Volume with Simultaneous Equilibration :
Dedicated pressure transducers on each sample station reduce void volume and allow simultaneous equilibration of all stations.
• Low Pressure Operation:
Optional pressure transducers for increased precision at low pressures are available. Optional turbomolecular pump to allow low-pressure measurements.
• Space Saving Design:
Reduces clutter and saves valuable bench space.
• Vacuum Pump Protection:
Integrated cold trap prevents vapors from entering the vacuum pump and reducing its efficiency.
• Sensitive Sample Protection:
Optional isolation valves protect sensitive or hydroscopic samples when transferring them from the outgasser to the analysis station.
• Flexible Software Interface:
Powerful Windows® based software provides a flexible interface for setting up experiments, controlling instrument functions, and displaying data. A full complement of classical and modern models for data reduction and display is included.
• Easy Setup:
The system is supplied complete and ready for operation. Vacuum pump, circulator, tubing, samples cells, etc. are all included.
