The STABIL VI® is comprised of the main unit which operates the two heavy aluminum heating blocks - each block with 10 test tube holder holes. The temperature of the block is guided by a control unit which contains a temperature controller and a limit controller. The limit controller operates an independent alarm circuit which turns off the heating unit if the temperature were to accidentally increase above a specified limit. For small testing batches only one heating block may be used if desired.
The main unit contains two temperature controllers and two safety (limit) temperature controllers (one for each heating block); a data acquisition unit (for the continuous recording of signals from one to twenty pressure transducers); a stabilized and dedicated power supply for the transducers and a data port for a personal computer. The data acquisition unit also processes signals from a barometric pressure transducer and a temperature sensor continuously measures the ambient pressure and temperature for the duration of the testing period. Two heating blocks can be operated simultaneously all at different temperatures. Up to 20 samples can be tested simultaneously with different beginning and ending of measurements. Temperature sensors in the heating blocks are calibrated and a conversion table is included in the software. WINSTAB™ software for Windows 7 continuously records and evaluates the evolution of gases generated by decomposition, evaporation or sublimation of the sample.
Automatic measurement and evaluation user-friendly software
Continuous Pressure-Time Record and automatic calculation for Volume-Time Dependence
Adaptability of design--the instrument and software are able to be customized
Calibrated volumes of test tubes and pressure sensors
Automatic temperature calibration
1 to 20 independent sample measurements may be conducted simultaneously
The unique design of the STABIL VI® completely updates and replaces all comparable old mercury-containing apparatuses and is the standard of excellence
Independent alarm circuit for monitoring of temperature (to avoid overheating)
Rate of pressure rise and overpressure inside test tubes are monitored by WINSTAB™ software as a part of the alarm functions
