    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.






    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 modeViscosity or Calibration
    TerminationStatic = Fixed number of consecutive measurements
    Dynamic = Number of measurements depend on pre-set conditions
    Warm-up timeFixed time for having sample thermally stabilized in viscometer tube
    Pre-heating timeTime to allow sample being pre-heated (note: pre-heater is optional)
    Reduced vacuumFilling viscometer with reduced may prevent premature evaporating of low volatile components and/or may reduce formation of gas bubbles
    Cleaning methodDifferent 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.
     

    NameDefined name will show up in operating method
    Injections solvent 1Number of injections of primary solvent, e.g. toluene
    Injections solvent 2Number of injections of secondary solvent, e.g. acetone
    Injection quantityAmount of solvent per injection
    Drying timePre-set time
    Thorough cleaningWhen 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.
