JBT07B Automatic Bubble Tension Measuring Instrument

JBT07B automatic bubble tension measuring instrument

Technical principles
The tested liquid sample into a heated container , one made of glass or Teflon capillaries will be immersed in a given depth of immersion liquid , the capillary tube connected to a gas port and a pressure sensitive sensor , in during the test, a gas or an inert gas through a capillary , the capillary end in the formation of bubbles , and the measured pressure of the bubble .

When the bubble pressure tensiometer JBT07 continuous increase the gas flow rate , the frequency of bubble formation is accelerated, a corresponding reduction in the survival time of each bubble . During the experiment set blebbing speed and frequency . When the bubble radius and the end portion of the capillary is equal to the radius of the capillary , the bubble pressure reaches maximum. Once the bubble radius than the radius of the capillary , the bubble pressure is significantly reduced. The maximum bubble pressure and dynamic surface tension proportional. Immersion depth is proportional to the hydrostatic pressure P and the capillary .

System parameters

2. :( bubble frequency range and depend on the liquid used capillary ): 0.05-30 Hz
3. Level Control : Precise control surface position
4. According to the liquid bubbles :( life decisions and capillary used ): 5 ms - 50 sec
5. The number of bubbles collection: 1-20 bubble / sec
6. Temperature range: room temperature or -5 ° C-95 ° C ( requires external water bath )
7. Temperature resolution : ± 0.1 ° C
