SDM Scientific
sdm S.D.M.™ Apparecchi Scientifici is an Italian company with its headquarters in Torino. The company was established in 1997; thanks to a highly skilled technical team. The roots and the ability of the company go back on a historical gain, with years of experience in manufacturing, designing and performing.A wide range of analyzers for petroleum testing therefore allows us to expand and develop new analytical platform. This allows the client the possibility to keep their analyzers up to date while giving them highly qualified technical and engineering support.

In order to satisfy its clients, S.D.M.™ launched a vast and complete range of manual and digital analytical instruments onto the market which are builded on petroleum methods platform.

  • Sample pre-heater (1 per tube; up to 150 °C)
  • Compressor
  • Cooling Spiral & External chiller
  • Pedestal base

Standard included software

U-VIsc utilizes advanced and easy to use multi-lingual  software. One PC can control up to 4 different systems (1 COM-port required for each instrument). Data can be exchanged with a LIMS via RS-232 or wireless. The instrument can be operated in its entirety through the PC interface. Sample ID’s can be loaded and sample queues  can be started, halted or temporarily suspended. Results are automatically stored in the internal database and optionally also on any external drive or network folder.

During  a  run  several  kind  of  information  is  shown  like  measured  flow  times,  average,  spread  and calibration  /  viscosity  result.  Also  actual  status  like  filling,  cleaning,  etc  is  shown  for  every  unit involved.  Measured  flow  times  are  presented  in  left  or  right  column,  depending  whether  upper  or lower  measuring  bulb  is  used  for  testing.  Sample  queue  is  permanently  present  and  can  be  edited any time without interrupting running samples.

U-VIsc-software1

A unique feature of U-VIsc software is its ability to define and store different operating methods, including different ways for cleaning and drying tubes. Methods can be set up for viscosity measurement or calibration and involve a number of configurable steps.

Operating mode Viscosity or Calibration  U-VIsc-software2
Termination Static = Fixed number of consecutive measurements
Dynamic = Number of measurements depend on pre-set conditions
Warm-up time Fixed time for having sample thermally stabilized in viscometer tube
Pre-heating time Time to allow sample being pre-heated (note: pre-heater is optional)
Reduced vacuum Filling viscometer with reduced may prevent premature evaporating of low volatile components and/or may reduce formation of gas bubbles
Cleaning method Different pre-defined viscometer cleaning methods can be chosen from

Omnitek U-VIsc allows for defining several methods for cleaning of viscometer. This offers great advantages in operations as for any kind of fluid optimized cleaning parameters can be set.

Name Defined name will show up in operating method  U-VIsc-software3
Injections solvent 1 Number of injections of primary solvent, e.g. toluene
Injections solvent 2 Number of injections of secondary solvent, e.g. acetone
Injection quantity Amount of solvent per injection
Drying time Pre-set time
Thorough cleaning When set it will allow for intensive solvent spraying

Multi-Lingual

New multi-lingual software allows for controlling all analysis procedure in different languages.

Viscosity index (VI)

VI is calculated either automatically or manually. Software gives VI automatically for same sample ID’s. It is also possible to calculate VI by choosing two different sample IDs manually.
