Anton Paar launches atmospheric distillation unit Diana 700

Perfection from the first drop

Anton Paar has launched Diana 700, the ideal solution for automatically performing high-precision distillation range analysis at atmospheric pressure. Typical samples to be analyzed include petrochemical products, aromatic hydrocarbons, and other volatile organic liquids. The combination of premium technology and distinguished features leads to unrivaled ease of use, high efficiency, and safe operation.

Support and automation for reliable results

To simplify the preparation of a measurement, Diana 700 supports you with several built-in features to provide maximum ease of use.

The intelligent condition monitoring system controls all steps that are necessary to perform a distillation and only allows a start if every step was completed successfully. Users do not lose time on test repeats due to incorrect setup or non-compliance with the standard.

The instrument has a high degree of automation, the heater and protection shield move up automatically after the flask has been installed using the unique and mobile multi-plug.

Untrained users benefit from illustrations that explain the procedure that is necessary to start a distillation step-by-step. For experienced users, an advanced mode enables a quick start.

Convenience combined with efficiency

For a smooth operator experience and to increase the usability of the instrument, the multi-plug combines the vapor temperature sensor and the flask mounting device. With just one hand it is possible to install the 125 mL or 200 mL flask within seconds in the correct position.

The receiving chamber of Diana 700 ensures very easy operation. Thanks to the tight jacketing of the receiving cylinder, the cooling chamber guarantees excellent stability of the sample and cylinder temperature.

Because of the highly efficient  Peltier tempering technique for the condenser and the receiving chamber, Diana 700 ensures  fast switching between different ASTM D86 distillation groups and reaches the required temperatures in less than five minutes.

The volume detection makes use of the high accuracy of contact imaging sensor technology (CIS) in order to achieve a precise and continuous determination of the sample volume throughout the distillation. Additionally, the volume is measured by the instrument before the test starts and corrected to 100 % volume if required.

 Evaluation of valuable customer feedback and using state-of-the-art technology, Anton Paar has designed Diana 700 as a modern and easy-to-use instrument.  Utilizing these features to provide user support, operational efficiency and class leading safety.

New ASTM test method for oxidation stability is supported by the Anton Paar Rapidoxy 100

RapidOxy 100 Header Image PR fireThe first standard method for Anton Paar RapidOxy 100 has been introduced, especially for analysing the oxidation stability and decay of lubricating grease.

Oxidation stability and ultimately the shelf life is an important criterion for many products. With the RapidOxy 100 from Anton Paar this can be determined precisely. The measuring device was launched on the market at the beginning of this year. The measuring principle is based on how much oxygen can be absorbed and chemically bound by a product and has been in use across a wide spectrum of industries for over ten years.

Following requests from the grease and lubricant industry, The American Society for Testing and Materials (ASTM) have published an official standard method with the RapidOxy 100 under the title “ASTM D8206: Standard test method for oxidation stability of lubricating greases – Rapid Small Scale Oxidation Test (RSSOT).” Preparation of the new method involved extensive inter-laboratory trials involving RSSOT users from across the USA and Europe.

The test procedure is quite simple. The technician fills four grams of the sample into a glass dish, puts it into the RapidOxy 100 and loads the device with pure oxygen under a pressure of 700 kPa. When heated up to a maximum of 180 degrees, the pressure drop in the measuring chamber is observed. The pressure drops because oxygen reacts with the sample and is this way consumed. Thus, the pressure drop is a measure for the oxidation and the “decay” of the sample.

The recently published ASTM standard method deals with the spoilage of lubricating grease. “Oxidation of the grease leads to a loss of lubricity; the grease becomes harder and can clump, for example. Furthermore, oxidation products can form that corrode or damage the machinery instead of lubricating it,” explains Gerold Tandler, head of product lines at Anton Paar ProveTec.

This information is essential for both grease manufacturers and end users. The advantage of the RapidOxy 100 compared to competing products: “It is faster and much more accurate,” explains Gerold Tandler. The goal to create a new modern standard test procedure which eliminates the drawbacks of the existing methods has been achieved.
