The answer is: Yes, this is a core feature of what makes them "fully automatic."
Fully Automatic Kinematic Viscosity Testers typically integrate automated cleaning and drying functions. Their workflow is as follows:
1.Measurement Completion: After the instrument finishes testing a sample.
2.Automatic Waste Disposal: The measured waste liquid is first automatically discharged into a designated waste collection bottle.
3.Solvent Cleaning: Next, the instrument uses its built-in pump and valve system to automatically draw in cleaning solvent.
The solvent will flush, soak, and purge along the same path as the sample (including the capillary tube, measuring cell, tubing, etc.) multiple times.
This cleaning process is usually repeated 2-3 times to ensure complete removal of any sample residue.
4.Drying and Purging: After cleaning, the instrument will draw in air or an inert gas (such as nitrogen) to completely dry the entire flow path system through purging, preparing it for the next sample test.
5.Ready: Once the entire cleaning and drying process is complete, the instrument automatically prepares for the next sample test.
The advantages of this automated cleaning are significant:
High Efficiency and Time-Saving: Eliminates the need for manual disassembly and cleaning, greatly improving experimental efficiency, especially for continuous testing of batch samples.
High Consistency: Avoids human operational variability, ensuring consistent cleaning results every time, thereby improving the accuracy and repeatability of test data.
Improved Safety: Significantly reduces operator exposure to harmful chemical solvents.
