Advanced Heater Control
Heater control, one of the distillation unit’s core tasks, can be challenging around IBP and FBP detection as well as for keeping the distillation rate between 4 – 5 ml per minute., epecially for unknown or difficult samples. STARDist detects the distillation behaviour at the earliest stage, allowing its advanced algorithm to dynamically set the exact right amount of heater power throughout the test.
Methods: ASTM D86, D1078, D850, E123, IP195, DIN51751, ISO 3405, GOST 2177, JIS K2254.
User interface: iPad with STARDist app software. Available in the App Store. App & updates are free of charge.
Operator support features: PreScan: volume and temperature of a sample-filled receiver are measured in the receiving chamber before each test. Actual measured volume is then corrected to 100% volume. Receiving chamber temperature is automatically set to sample temperature, provided it is within the method-prescribed limits. START check: 1. Heater plate size. 2. PT-100 probe placed in the flask. 3. Heater door closed. (Must be confirmed before the test to start) Results validation: quick pass / fail test validation against method-prescribed limits such as “time to IBP”, “FBP temp.”, etc. Optimization: automatically optimizes program settings with fixed InHeat and Final Heat settings after the first distillation test. Flask Installer ensures easy and correct upright flask positioning for both 125 ml and 200 ml flasks. The vapor probe’s height position relative to the flask’s sidearm is always correct thanks to the vapor probe design in combination with the strict flask dimensions.
Heating control: Kalman Filter technology: multiparameter-based algorithm calculates and applies the required heater settings for IBP, FBP and (4-5 ml/p min.) speed control in real-time. Suitable for unknown samples and/or complicated blends such as E20.
Heating system: Low mass/low voltage heater. 2 user adjustable fans for extra fast cooling after test. Automatic heater lift with correct flask pressure & positioning. Automatic shut-off in case of fire.
Condenser cooling: Solid state: based on Peltier elements with heat-pipe assisted heat sinks and silent fans for heat dissipation. No liquids involved. Condenser temperature can be increased during the distillation to deal with “light start / heavy end” products to prevent both evaporation loss and product waxing in the condenser tube. Temperature range: 0 – 65°C. Resolution 0.1°C.
Volume detection: Smart HD CCD camera for accurate volume measurement. Detects actual bottom of the meniscus. Suitable for “smoke producing” products. Each-test automatic calibration of the camera based on calibrated ring marks on receiver cylinder. Resolution: 0.01 ml, accuracy: 0.01 ml, charge volume: 0-105%.
Receiving chamber: Built-in drop deflector. Cooling: similar to condenser cooling. 1 sensor for receiver chamber temperature and 1 sensor for sample temperature. The automatic lift moves receiver cylinder up to be sealed at the top, where a small hole ensures exposure to atmospheric pressure. A small tube, laid along the condenser tube and connected to this hole, acts as “VOC Cold Trap”, preventing vapors from escaping the receiver (loss). At the end of this tube a VOC extractor can be connected dissipate VOC emissions. Temperature range: 0 – 45°C. Resolution 0.1°C.
Residue & Loss: Various options: automatic prediction, automatic measurement, manual measurement and the pre-set value. Loss correction is automatically applied to temperature readings.
Vapor temperature measurement: PT-100 class A probe with 10-point calibration data storage and automatic probe ID detection. Calibration certificate standard supplied. True dynamic simulation of ASTM 7 & 8 in-glass thermometer behavior (lag time and emergent stem). Range: 0 – 450°C ASTM / 0 – 500°C absolute. Temperature units: ºC, ºF.
Dry point detection: Optical Dry Sense: IR sensor for automatic detection of the drypoint. No dry point probe required. (Conventional dry point probe is still available as an option)
Pressure: Built-in pressure sensor. Automatic correction of temperature results to atmospheric pressure. Range: 70 to 110 kPa, resolution 0.1 kPa. Pressure units: kPa, mmHg, mbar, psi, mWc, hPa.
Cetane index: Function for automatic calculation of cetane index included.
Fire safety: UV sensor for fire detection. Built-in fire extinguisher. N or CO2 supply required from the lab
System health: Automatic quick system health check before every distillation run to ensure all components are in excellent state.
