Portable and Automatic Mini-Distillation Analyzer for the Distillation of Petroleum Products at Atmospheric Pressure

The MINIDIS ADXpert is a real atmospheric distillation analyzer and is very compact, lightweight, and portable. It functions as a completely stand-alone unit and is intended for fast and precise quality control in laboratories and in the field. It requires as little as 6 mL of sample and takes just 15 minutes for a distillation run on light products. The compact size of the portable mini-distillation apparatus allows it to be the ultimate solution for places where there is restricted or no lab-space.


From the introduction of the sample to heating regulation, vapor temperature registration, volume measurement in the receiver compartment, and estimation of the distillation curve from the raw data obtained during the test, MINIDIS ADXpert is completely automated. Thus, it realizes the highest levels of repeatability, reproducibility, and accuracy. In the automatic operation, the filling tube is simply inserted into the sample container and “RUN” is pressed. It does not require sample preparation such as cooling.

Also, there is no need for prior distillation knowledge or special programming of the test conditions. Completely automated cleaning programs and the use of inexpensive and disposable sample cups ensure the highest productivity and avoid manual cleaning of glassware.

MINIDIS ADXpert operates as per ASTM D7344, the New Mini-method for the Distillation of Petroleum Products at Atmospheric Pressure, and produces comprehensive D86 test reports. The distillation apparatus has a resolution nearly twice as good as D86 distillation units, producing results that satisfy the ASTM D86 r/R demands. The highly versatile unit enables accurate testing of a variety of jet fuel and diesel products (groups 0–4), gasoline, biofuels, aromatics, solvents, chemicals, organic liquids, and contaminated or mixed samples.

Transforming ASTM D86 Testing

The automatic distillation analyzer MINIDIS ADXpert is transforming ASTM D86 testing. It is a genuine atmospheric distillation analyzer in a very small format. The automation considerably enhances the reproducibility and the repeatability of the highly accurate results. The MINIDIS provides a comprehensive ASTM D86 compliant report and prints and/or transmits the results through a serial PC connection.

Exceptional: Highest Safety

One of the main causes of fire hazards faced when distilling with glass flasks is broken glassware. The strong metal housing, the small sample volume, and the sealed metal distillation cycle of the MINIDIS ADXpert eliminate the need for a fire protection system. The consumable costs are considerably decreased by using inexpensive and resilient metal sample cups instead of costly glass flasks; thus, the MINIDIS ADXpert is an ideal solution for distillation testing within demanding environments.

Complete Automation for Highest Productivity

A full distillation run and test report is offered by the MINIDIS ADXpert in 15 minutes (for gasoline) by using just 6 mL of sample. In the automatic operation, the filling tube is just inserted into the sample and “RUN” is pressed. There is no need for special programming of test conditions or prior distillation test knowledge. The automatic sample introduction, the use of disposable sample cups, and the pre-programmed rinsing cycle eliminate test preparation or manual cleaning of glass parts.

Unrivalled Versatility

It can be used for jet fuel and diesel products (groups 0–4), gasoline, solvents, biofuels, organic liquids, aromatics, chemicals, and contaminated or mixed samples. Due to its rapid measurements, automatic cleaning, and nearly no waste operation, it finds versatile applications in laboratories, in Mobile or at-line Labs.

Problematic Samples? No Problem!

Traditional D86 distillation analyzers frequently come across such “problematic” samples. In the majority of cases, D86 analyzer cannot measure mining solvents, raffinates, and condensates. MINIDIS ADXpert includes a versatile temperature control for a very small sample volume, which enables quick and effortless heater adjustment. Therefore, even “problematic” samples can be distilled until the final boiling point is achieved. The highly precise volume detection system enables accurate and repeatable analysis of Biofuels and vegetable oils mixtures.

True Portability for All Applications

MINIDIS ADXpert works as per the new D7344 standard for true atmospheric distillation. Results of the MINIDIS ADXpert correspond well with the results of D86, ISO 3405, IP123, and DIN51751. Due to the completely automatic measurements, the temperature-controlled sample introduction, and an advanced automatic heating program, sources for D86 distillation operator bias are eliminated.

The tough housing, true portability, and optional 12-V vehicle battery operation featured in MINIDIS ADXpert make it the ideal solution for all types of applications, where standard laboratory instrumentation are not applicable, for example, measurements in the field or in mobile laboratories.

What Customers Say About the New MINIDIS ADXpert

The new MINIDIS ADXpert is very easy to use, works fully automatic and produces highly repeatable results in comparison to ASTM D86 analyzers. We especially like the small sample volume and the program for automatic cleaning.

Eva Galdova, Head of Mobile Laboratory, SGS Czech Republic

We have purchased the Grabner MINIDIS as an alternative to traditional D86 distillation units. It has proven its performance and reliability in our lab. Easy to use with automated sample handling, low maintenance costs, using only little space on our lab bench: My staff loves the MINIDIS!
