The Viscosity Measurement System is a specialized and automated testing equipment designed for measuring 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, corresponding to dual, quadruple, and sextuple test unit configurations, respectively. These setups can simultaneously accommodate two, four, or six viscometers.

UtilizeNcy-xViscosity Automatic Measurement System Ahead:

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

formerly a manual determination of data validity

Just 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 continue to automatically retest and eliminate out-of-tolerance results, ensuring accurate flow time.

The system still retains the JWC precision constant-temperature bath, a result of our 1990s national research project, and continues to provide a temperature fluctuation and distribution of better than ±0.01℃ over long periods, ensuring consistent test data at any moment and position.

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

An automatic liquid dispenser with a precision of up to 0.1% for concentration, allowing for convenient preparation of sample solutions (one-touch dispensing).

A double-glass isolation design of the sample bottle ensures that the prepared solution dissolves quickly and evenly in the jingque thermostatic oscillating bath,不受水分干扰.

Automated Liquid Delivery System, eliminating the need for manual feeding of the viscosity tube. A comprehensive unit 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 liquid injection - soaking - recovery - cleaning - drying, without the need for manual intervention.

System Structure

2. Layout of the 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 requirements, but its basic principle is:

2.1 Ensure all pipeline distances are as short as possible, while also considering actual operations such as filling and pouring. The cover image illustrates a typical rational 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 Handling

3.1 Automated Solution Preparation

See PY Automatic Mixture Dispenser manual (optional accessories).

3.2 Quick Dissolution of Samples

Please refer to the WR-2 Rapid Sample Dissolution Oscillator manual (optional accessory), featuring a sample dissolution bottle with a double-layered insulating sleeve.

The dissolution process of the sample in the solvent can sometimes be quite lengthy, taking one hour or even more. It requires oscillation at as high a temperature as possible to accelerate the process, but 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 liquid intake and testing of viscometers, transmission of cleaning fluids, and drying. Different vacuum pressures need to be adjusted according to the solvent components of the samples and cleaning fluids.

Vacuum Pressure Adjustment Method:

Two pressure gauges are located on the central control system panel: one for adjusting and controlling the working pressure of the sample solution with a constant pressure gauge, and the other for regulating and controlling the working pressure of the washing fluid with a pump pressure gauge.

Vacuum pressure regulation methods are as follows:

Press the mode key (left button), until it shows L0-2, which shows the current lower limit of 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 maximum vacuum level is displayed. Press the up and down keys to change the maximum set value.

Note: The vacuum pressure value is negative.

5. Liquid Inlet and Testing

Prepare a clean empty solvent sample bottle, pour half of the solution from the solvent bottle in 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 (for rinsing) is in the position of the liquid aspirator, then lower the aspirator into the volumetric flask while the mouth of the flask for the test is automatically covered. After initiating the test, the testing system will automatically draw the solution from the solution bottle, complete the rinse, and then automatically discharge the liquid.

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

Sample Dissolution Bottle Location

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

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

Test completed, solvent bottle returned to starting position.

After launching 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; 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 vial in the rinse position (it can also be the test position) of the sampler, and the pipette will automatically insert into the bottom of the bottle (this is very important!!)

Check and ensure there is an adequate supply of solvents like detergents, and 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 "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 bottle requires regular monitoring of the liquid level. For waste liquid collection, timely cleaning is necessary when the level is high; for new liquid, it's important to replenish promptly.

When removing the bottle cap, pay attention to the original state of installation. Some may come with a layer of Teflon film, which is to address the issue of cap corrosion. When reinserting the plastic tube, be sure to note the tube's number and the corresponding entry marked on the bottle label. When replacing the cap, make sure it is tightly sealed and check for a proper seal.

7.2 Vacuum Pump

When this type of vacuum pump is in use, if the intake maintains vacuum (low pressure), it can cause the oil pump to spray oil from the intake to the outside. This unit has been equipped with a special program in the control system to prevent oil spilling, but after a considerable period of use, the oil level will also decrease. When the oil level in the oil gauge on the pump side falls below "min," add vacuum pump oil from the intake to between the two oil gauge marks.
