SITA automatic interfacial tension instrument, can be equipped with strong acid protection kit 1

product description

The German SITA column surface tensIon Meter can measure the dynamic and static surface tension of liquids, monitor the quality of the bath liquid during the cleaning process, and establish a good foundation for R&D and cleaning processes to obtain high-quality results. The SITA fully automatic interfacial tensIon Meter Science Line t100 surface tensIon Meter is a high-performance laboratory surface tensIon Meter with high accuracy, simple operation, fast and flexible, and can be used to measure the active agent performance, aging process and Material stability. Science Line t100 surface tensIon Meter is a SITA brand testing instrument imported from Germany. It has been widely used in cleaning agents, wetting agents, inks, coatings and cosmetics industries to achieve quality control effects.

Principle

The bubble pressure method is used to measure the dynamic and static surface tension of liquids without the need to precisely control the capillary immersion depth. The measurement accuracy is high and the operation is flexible. Air is blown through the capillary tube into the liquid to be measured. The pressure inside the bubble continuously changes as the bubble radius changes. Therefore, surface tension can be calculated from the difference between the maximum and minimum pressure values. The instrument can be automatically calibrated using pure water.

Function

Science Line t100 Surface Tensiometer has three major functions including Auto mode, Online mode and Single mode.

Auto mode: Different bubble lifespans can be adjusted within the range for measurement

1. Surfactant performance evaluation

2. Analyze the stress theory of surfactants

Online mode: continuous measurement

1. Measure the dependence of sample surface tension on temperature

2. Analyze the aging process

3. Evaluate the stability of the sample

Single mode: single measurement

1. Implement control and testing functions

2. After establishing the relationship curve between surface tension and concentration, the sample concentration can be measured.

Two major advantages include high accuracy and flexibility.

High accuracy: The measurement principle of surface tension adopts the pressure testing method, which avoids the influence of immersion depth on the results. The bubble life range is from 15ms (high dynamic) to 100000ms (quasi-static), and it can be automatically calibrated with water.

Flexibility: The device is safe, fast and easy, the operation is simple and easy to understand, the portable and reliable storage box has a built-in effective battery to achieve long-term battery life.

use

Used in product research and development of inkjet ink, coating ink, additives, cleaning agents, activators, plating solutions, daily chemical products, alcohol, and petroleum industries, and control of cleaning effects of precision electronic workpieces. By testing the surface tension of the liquid, we can determine the concentration of the surfactant, the migration speed of the surfactant and the wetting and leveling performance of the liquid. like:

Control surface tension and surface activity during production and quality inspection;

In factories and laboratories, monitoring the surface tension of surface-active fluids;

Test the quality of inkjet inks;

Quality control of raw materials including surfactants.
