Overview

A viscosity detector is an analytical instrument similar to a starch viscosity meter used to determine the characteristics of starch paste. While heating up, a flour water solution is mixed. Due to the gelatinization and degradation of starch, the dryness of the solution will change. At this time, a food instrument can be used to record the changes.

The SPC/L301 viscosity detector is an analytical instrument similar to the starch viscosity meter used to determine the characteristics of starch pasting. While heating up, a flour water solution is mixed. Due to the gelatinization and degradation of starch, the dryness of the solution will change. At this time, a food instrument can be used to record the changes.

　　1、 Experimental principle

The molar mass of a polymer not only reflects the size of its molecules, but also directly affects its physical properties, making it an important fundamental parameter. Unlike typical inorganic or low molecular weight organic compounds, high polymers are often mixtures of large molecules with different molar masses, so the measured molar mass of high polymers is usually a statistical average.

　　2、 Structural characteristics

The SPC/L301 viscosity detector consists of an electronic control system, bath, stirring motor, viscosity meter holder, and other components. This device is equipped with four viscometer holders, allowing for simultaneous testing of samples and maintenance of other temperatures. Our viscometer holder has a clever design that allows for easy vertical fixation of the viscometer by adjusting the three positioning screws on the holder.

　　3、 Main functions of viscosity tester

1. Easy to disassemble and assemble, easy to start measurement;

2. Digital display: displays viscosity,% torque, speed, rotor number, and viscosity upper limit;

3. Automatic diagnostic function;

4. Under critical measurement conditions, emit sound and light signals;

5. Digital torque calibration device with full tracking standard;

　　4、 Usage conditions

1. The instrument should be placed in a dry, clean, and non corrosive gas environment, and should be placed on a flat and stable test bench.

2. The liquid measured by the instrument is a Newtonian liquid, and its viscosity is independent of shear stress and shear rate.

3. Within different testing temperature ranges, different constant temperature bath liquids should be used for the constant temperature bath.

　　5、 Precautions

1. The heating control switch must not be turned on before the constant temperature bath is filled with transformer oil.

2. When using continuously, attention should be paid to whether the liquid level of transformer oil in the constant temperature bath has decreased. If it is too low, it should be replenished at any time. If there are impurities in the transformer oil, they should be promptly treated, eliminated or replaced.

3. Pay attention to replenishing cleaning solution and draining waste oil from the waste liquid storage container. Otherwise, it will cause serious malfunctions or accidents to the instrument.

4. The number of samples loaded into the oil cup should not be too large, as too much will cause the test solution to seal the lower end of the capillary tube, affecting the operation of the viscometer. The number of samples loaded should not be too small, so as to create a vacuum during measurement.

　　6、 Maintenance and upkeep of viscosity tester

1. Verify the availability of the device

Before using the instrument, first observe whether the appearance of the instrument is damaged. After powering on, check if the instrument head displays properly and if the display is complete. For instruments that have not been used for a long time, check if the output terminal is corroded or aged. Otherwise, they should be cleaned up in a timely manner before use. Please refer to the 'User Manual' when using.

2. Equipment maintenance

After each experiment, clean the wires on the instrument terminals, turn off the power, disconnect the power plug, cover the computer case, and place it in a dry, dust-free, ventilated, and non corrosive indoor environment.
