The viscosity measurement system is a specialized, automated testing equipment designed for determining the intrinsic viscosity, viscosity number, average polymerization degree, and viscosity average molecular weight of polymers. Depending on the number of test units configured in the system, it is categorized as NCY-X/2, NCY-X/4, and NCY-X/6, with corresponding configurations of two, four, and six test units, respectively. This allows for simultaneous use by two, four, or six viscometers.

UtilizeNcy-xViscosity Automatic Measurement System Ahead:

The measurement of the time required for a certain volume of solution, previously performed manually, to flow through a capillary.

Originally, the determination of data validity was done manually.

Like the NCY Automatic Viscosity Meter, it will still be executed by the system.

The system will still display the flow of the solution in the capillary viscometers of each unit in real-time and visually.

The system will still automatically repeatedly test and eliminate out-of-tolerance results, ensuring accurate flow times.

The system still retains the achievements from our 1990s national research project—the JWC precision constant-temperature bath—and continues to consistently provide temperature fluctuations and distributions better than ±0.01℃ over extended periods, ensuring the consistency of test data at any moment and location.

In addition, the automatic testing system will feature the following new functionalities:

Automated liquid preparation instrument with accuracy up to 0.1% for conveniently preparing sample solutions (one-touch liquid preparation).

Double-layer glass isolation designed sample bottles allow the prepared solution to dissolve quickly and uniformly in the precise oscillating bath, unaffected by moisture interference.

Automatic liquid delivery system, no longer requiring manual feeding of the viscosity tube, a comprehensive device that automatically filters the solution and delivers it into the capillary of the viscometer.

Automatic test completed; the system will automatically extract waste liquid and wait for the arrival of the next sample to automatically complete the capillary rinsing and testing.

When cleaning capillaries is required, simply activate the cleaning program, and the system will autonomously complete the entire process of washing fluid introduction, soaking, recovery, cleaning, and drying, without the need for manual intervention.

2. Layout of the automatic viscosity measurement system

This automatic testing system is composed of several components and can be arranged in various configurations according to the user's setup, but its fundamental principle is:

2.1 Ensure all pipeline distances are as short as possible while also considering practical operations such as filling and emptying. The cover image illustrates a typical reasonable layout.

2.2 The pipeline connecting from the central control unit to the viscometer must start from the central control system and gradually decrease, with no peaks in between.

3. Sample Handling

3.1 Automatic Solution Preparation

See the PY Automatic Mixture Dispenser manual (optional accessories).

3.2 Rapid Solubility of Sample

See WR-2 Rapid Sample Dissolution Oscillator manual (optional accessory), equipped with a double-layered insulating sleeve sample bottle.

The dissolution process of the sample in the solvent can sometimes be very lengthy, taking one or even more hours, and requires shaking at as high a temperature as possible to accelerate the process. Excessive temperature will lead to degradation, so the temperature should be precisely controlled.

4. Vacuum Pressure Adjustment

The automatic testing system operates under vacuum pressure. This system is equipped with different pressure sources specifically for the fluid intake and testing of viscometers, transmission of cleaning fluid, and drying. Different vacuum pressures need to be adjusted according to the solvent components of the sample and cleaning fluid.

Vacuum Pressure Adjustment Method:

Two pressure gauges are located on the control system panel. The constant pressure gauge adjusts and controls the working pressure of the sample solution, while the pump pressure gauge adjusts and controls the working pressure of the washing fluid.

Vacuum pressure regulation methods are as follows:

Press the mode button (left button), until "L" appears0-2 shows the lower limit of the current vacuum setting. Press the up and down keys to adjust the upper limit setting.

Press the pattern key again to display H1After -2, the current upper limit of vacuum degree is displayed. Press the up and down keys to adjust the upper limit setting.

Note: The vacuum pressure value is negative.

5. Liquid Inlet & Testing

Prepare a clean empty solvent sample bottle, remove the solvent bottle containing the dissolved sample from the oscillator, pour half of its contents into the empty solvent bottle, and place them together in the corresponding sampling unit position.

During testing, only approximately 13mL of sample is required. Therefore, if rinsing is necessary before testing, you will need to prepare about 26mL of solution at once. Place the solvent bottle on the autosampler, press the rinse button for the corresponding unit, and the solvent bottle holder advances. Stop when the previous solvent bottle (for rinsing) is in the position of the pipette, then lower the pipette to insert it into the volumetric flask, while the flask for the test sample is automatically sealed. After initiating the test, the testing system will automatically draw the solution from the solvent bottle, complete the rinse, and automatically drain the liquid.

Keep pressing the test button, another sample vial is sent to the testing position, waiting for the test to start. Once the test is complete, the sample vial is returned to the starting position.

Sample solution bottle location

Washing Station: The suction tube is inserted into the front beaker, and the opening of the subsequent beaker is automatically sealed.

Test port: Insert the syringe into the vial at the back.

Test completed, reposition the dissolution bottle to the starting position.

After initiating the test program for this unit on the computer, the unit automatically enters the working state. The subsequent operations are performed automatically by the system. The operator can view the progress of the unit's testing on the screen, and a dialog box will automatically pop up when issues are encountered during the test.

Test completed; the system automatically discharges waste fluid before proceeding to the next test.

6. Capillary Viscometer Cleaning and Drying

Viscometers should be cleaned after being used for a period of time.

Firstly, place a solvent bottle into the rinse position (or test position) of the sampler, and the pipette will automatically insert to the bottom of the bottle (this is crucial!!)

Check and ensure there is an adequate supply of cleaning fluids and solvents, as well as potable water. Verify that containers for waste liquids and wastewater have sufficient remaining space.

Then, you can initiate and complete the entire cleaning-drying process.

Select "Wash Solution Immersion Cleaning" on the computer interface, the viscometer can complete the entire cleaning-drying process.

7. Routine Maintenance

7.1 Liquid Storage Bottle

The liquid storage bottles require regular monitoring of the liquid level. For waste liquid collection, timely cleaning is necessary when the level is high; for new liquid types, it is important to replenish promptly.

Remove the cap with care, noting the original state. Some may have a layer of polytetrafluoroethylene film attached to prevent corrosion. When reinserting the plastic tube, be sure to check the tube number and the corresponding entrance marked on the label. When replacing the cap, ensure it is tightly sealed and note the seal.

7.2 Vacuum Pump

During operation, if the suction inlet of this vacuum pump maintains vacuum (low pressure), it may cause the oil pump to spray oil outward from the suction inlet. The machine has a special program set in the control system to prevent oil leakage. However, after a certain period of use, the oil level may decrease. When the oil level in the oil gauge on the pump side falls below the "min" mark, oil should be added to the suction inlet of the vacuum pump until it reaches between the first and second graduation lines on the oil gauge.
