Wilhelmy Plate Tensiometer Du Noüy Ring Tensiometer Laboratory
Surface Tension Analyzer
Applicability:
Surface tension testers are widely used in scientific research,
industrial production and quality control fields.
Their main uses include:
Materials Science:
Measuring the surface tension of liquids such as coatings, inks,
adhesives, and evaluating their wettability and spreadability.
Chemical and petroleum:
Analyze the performance of surfactants and the interface tension of
crude oil, and optimize the process flow.
Pharmaceutical industry:
Detect the surface tension of the drug solution to ensure the
stability and dispersion of the drug.
Food Industry:
Research the surface characteristics of emulsifiers, beverages,
etc. to improve product quality.
Biomedicine:
Measuring the surface tension of biological fluids (such as blood,
cell culture fluids), assisting in disease diagnosis and research.
Characteristics:
1. Using advanced strain or electromagnetic force balance sensor,
with high precision, high repeatability characteristics.
2. Digital tube display mode, real-time display of the current
weight, the current surface tension value.
3. Design platinum plate, platinum ring at the same time two test
methods, can choose one of them, can also choose two at the same
time.
4. The surface tension value was collected in real time and the
surface tension curve was recorded in the whole process. The
software automatically displays the peak surface tension and
automatically converts the equivalent surface tension according to
the temperature.
5. Convenient lifting bracket for platinum plate and platinum ring,
which is very easy for users to unload, and the accuracy of force
value can be calibrated by standard weight at any time.
6. One-key peeling function, the number does not jump, zero drift.
7. Delicate ball screw lifting system, no noise, rising and falling
speed is stable.
8. Provide data collection and management software.
9. Meet but not limited to the following standards:
GB/T6541-86 ISO1409-1995 GB/T22237-2008 SH/T1156-95
