STARDist Optical Dry Point
StarDist Optical Dry point sensor is an ideal solution to avoid incorrect positioning of conventional sensors which will lead to inaccurate dry point detection.
No more expensive fragile dry point sensors
Pre Scan
StarDist automatic ASTM D86 distillation offers Pre Scan function that significantly increases the reproducibility of results.
Pre Scan measures both the volume and the temperature of the sample before each test.
The volume will be normalized to 100%, and the temperature will be the set-point for the receiving chamber temperature during the test. The same “start” temperature as the “recovery” temperature avoids temperature-induced volume expansion/shrinkage. which affects the distillation accuracy.
| Methods | ASTM D86, D1078, D850, E123, IP195, DIN51751, ISO 3405, GOST 2177, JIS K2254. |
| User interface | iPad with STARDist app software. Available in App Store. App & updates are free of charge. |
| Heating control | Smart 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. Speed control range: 2-11 ml p/min. |
| 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 meniscus. Suitable for “smoke producing” products. Automatic calibration of the camera against 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. Automatic lift moves receiver cylinder up to be sealed at the top, where a small hole ensures exposure to atmospheric pressure. Then; a tube laid along the condenser tube acts as “VOC Cold Trap”, preventing vapors from escaping the receiver (loss).Temperature range: 0 – 45°C. Resolution 0.1°C. |
| Residue & Loss | Various options for residue measurement: automatic prediction, camera measurement, manual measurement and preset 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. Units: ºC, ºF. |
| Dry point detection | Optical Dry Point: IR sensor for automatic dry point detection. No dry point probe required. (Conventional dp probe still available) |
| Pressure | Built-in pressure sensor. Automatic correction of temperature results to atmospheric pressure. Range: 70 to 110 kPa, res. 0.1 kPa. |
| Cetane index | Built-in function for automatic calculation of cetane index. |
| Fire safety | UV sensor for fire detection. Built-in fire extinguisher. N or CO2 supply required from lab (connection hose is supplied). |
| System health | Automatic quick system health check before every distillation run to ensure all components are in excellent state. |
| Connectivity | 1 x RJ45 (LAN) for connection to LIMS, Windows PC, FTP server, Kiosk printer and/or connection between multiple STARDist units. |
| Dimensions | Dimensions: 40cm x 40cm x 63cm (WxDxH), weight: 40 kg |
| Accessories | Kiosk printer |
| Voltage | 100-240 VAC 50/60 Hz |
| Power | 1200 W |
| Lab conditions | Environment temperature 10°C – 30°C. Environment humidity up to 80 % at 30°C. |
