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 mode||Viscosity or Calibration|
|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|
|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|
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.
