Atmospheric Distillation Analyzer :

Diana-700

• High-precision distillation unit for fuels and solvents
• Indestructible vapor temperature sensor that lasts forever
• Accelerated cooling between measurements means you save time and can start the next measurement right away
• Guides you step-by-step through the setup for distillation

Diana 700 is the ideal solution for automatically performing high-precision distillation range analysis at atmospheric pressure. Typical samples to be characterized include petrochemical products, aromatic hydrocarbons as well as other volatile organic liquids.

The combination of premium technology and distinguished features leads to unrivaled ease of use, high efficiency, and safe operation.

Key Features :

Smart operator assistance

• Diana 700 automates manual handling steps during the measurement setup to provide maximum support. Additionally, for untrained users the innovative user interface employs illustrations as a step-by-step guide through the procedure that is necessary to start a distillation. For experienced users, the advanced mode just shows the state of each component of the instrument and enables a fast start of the distillation. The intelligent condition monitoring system controls all steps and Diana 700 only allows you to start a measurement if all steps have been completed correctly. This helps you avoid having to repeat a measurement due to an incorrect setup or non-compliance with the standard.

Convenient handling: Mobile multi-plug with indestructible temperature sensor

• For a perfect operator experience and to increase the usability of the instrument, the vapor temperature sensor was combined with the flask holder. The resulting multi-plug is available in two variants: with the indestructible temperature sensor made of metal or with the classical sensor made of glass. Install the distillation flask (125 mL or 200 mL) in the correct position with just one hand and within seconds.
• The integrated data memory stores the calibration data of the temperature sensor which is automatically applied when the sensor is mounted to the instrument.

Operator convenience meets safety: Intelligent design for automated handling

• As soon as the distillation flask has been mounted the heater and the protection shield move up fully automatically. The correct flask and flask support board are identified by the instrument and the distillation can only be started if the correct type is selected.
• For a maximum level of safety, the automatic shield lift surrounds the flask, reducing the risk of touching any hot parts while a measurement is running. After finishing the test, the heater moves down to accelerate the cooling of the flask. This means you save time and can start your next measurement right away.

Efficient and easy to operate: The receiving chamber

• You can operate the receiving chamber of Diana 700 smoothly to access the receiving cylinder. Thanks to the tight jacketing of the cylinder, the chamber guarantees an excellent stability of the sample and cylinder temperature.
• Using the highly efficient Peltier technology, Diana 700 enables a fast switch between different ASTM D86 distillation groups and reaches the required temperatures in less than five minutes.
• A unique cold trap prevents condensation caused by high humidity and reduces evaporation losses of volatile organic compounds (VOC) at the same time.

Highly accurate volume reading

• The volume detection of the atmospheric distillation unit Diana 700 makes use of the high accuracy of contact imaging sensor technology (CIS) to achieve a precise determination of the sample volume. This technology has no moving parts to avoid malfunction of the instrument and is able to continuously follow the liquid level in the cylinder. Additionally, the volume is measured by the instrument before the test starts and corrected to 100 % volume, if necessary.
