The Viscosity Measurement System is a specially designed and developed automated testing equipment for polymer properties such as intrinsic viscosity, viscosity number, average degree of polymerization, and viscosity average molecular weight. Depending on the number of testing units configured in the system, it is divided into NCY-X/2, NCY-X/4, and NCY-X/6 models, each equipped with two, four, or six testing units respectively, allowing for simultaneous use of two, four, or six viscometers.

UtilizeNcy-xViscosity Automatic Measurement System Ahead:

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

The original determination of data validity, which was previously done manually,

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

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

The system will still automatically repeat testing and eliminate out-of-tolerance results to achieve accurate flow time.

The system still retains the research achievements from our national science and technology projects in the 1990s - the JWC precision constant-temperature water bath. It will continue to deliver temperature fluctuations and distributions better than ±0.01℃ over extended periods, ensuring consistency of test data at any moment and position.

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

Automated liquid preparation instrument with a precision of up to 0.1% concentration, capable of conveniently preparing sample solutions (one-button liquid preparation).

Double-glazed vials with isolation design, ensuring the prepared solution dissolves rapidly and evenly in a precise, constant-temperature oscillating bath, free from interference by moisture.

Automated Liquid Delivery System, eliminating the need for manual feeding of the viscosity tube. The comprehensive device 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 initiate the cleaning program, and the system will autonomously complete the entire process of liquid introduction, soaking, recovery, cleaning, and drying, without any manual involvement.

2. Arrangement of Automatic Viscosity Measurement System

This automated testing system is composed of several components, which 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 actual 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, without any rise in between.

3. Sample Processing

3.1 Automatic Solution Preparation

See the PY Automated Mixture Instrument manual (optional accessories).

3.2 Quick Dissolution of Samples

Refer to the WR-2 Rapid Sample Dissolution Oscillator manual (optional accessory), equipped with a sample bottle featuring a double-layered jacket.

The dissolution process of the sample in the solvent can sometimes be quite lengthy, taking one, even more hours, and requires oscillation at as high a temperature as possible to accelerate completion. 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 dedicated pressure sources for the injection, testing, transfer of washing fluid, and drying. Different vacuum pressures need to be adjusted according to the sample and the solvent composition of the washing 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 liquid.

Vacuum pressure regulation methods are as follows:

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

Press the mode key again to display H1After -2, the current maximum vacuum level is displayed. Press the up and down buttons to change the set maximum value.

Note: The vacuum pressure value is negative.

5. Inlet and Testing

Prepare a clean empty solvent sample bottle, pour half of the solvent bottle containing the dissolved sample from the oscillator 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 it's necessary to rinse before testing, you will need to prepare about 26mL of solution at a time. Place the solution bottle on the autosampler, press the rinse button for the corresponding unit, and the solution bottle holder advances. Stop when the previous solution bottle (used for rinsing) is in the liquid tube position, then the liquid tube descends and inserts into the volumetric flask, while the flask's mouth is automatically sealed. After initiating the test, the testing system will automatically draw the solution from the solution bottle, complete the rinse, and automatically drain the liquid.

Keep pressing the test button, another sample vial is sent to the testing station, wait for the test to start. Test completed, the sample vial is returned to the starting position.

Sample Solution Bottle Location

Wash position: The liquid suction tube is inserted into the front beaker, and the mouth of the subsequent beaker automatically covers it.

Test Port: Insert the liquid tube into the sample bottle at the back.

Test complete, reposition the solution 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 work is 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 if an issue is encountered during the test.

Test completed; after the system automatically discharges the waste liquid, it proceeds to the next test phase.

6. Capillary Viscometer Cleaning and Drying

After a period of use, the viscometer should be cleaned.

First, place a solution bottle in the rinse position (or test position) of the sampler, and the pipette will automatically insert into the bottom of the bottle (this is very important!!)

Inspect and ensure there is an adequate supply of solvents like detergents and potable water. Check and confirm that containers for waste liquids and wastewater have sufficient remaining space.

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

Select "Detergent Soak Cleaning" on the computer interface, and the viscometer can complete the entire cleaning-drying process.

7. Routine Maintenance

7.1 Liquid Storage Bottle

The 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, timely replenishment is essential.

Remove the cap with care, noting the original state. Some may come with a layer of Teflon film to address the corrosion issue. When reinserting the plastic tube, be sure to check the tube's numbering and the corresponding entry marked on the label. Tighten the cap securely when replacing it, ensuring a proper seal.

7.2 Vacuum Pump

This type of vacuum pump, when in use, if the suction inlet maintains vacuum (low pressure), it may cause the oil pump to spray oil outward from the suction inlet. The machine has been equipped with a special program in the control system to prevent oil spraying. However, after a considerable period of use, the oil level will also decrease. When the oil level in the pump side's oil gauge falls below the "min" mark, oil should be added to the vacuum pump from the suction inlet until it reaches the second marking on the oil gauge.
