Force Tensiometer – K20 The flexible tensiometer for basic quality assuranceOur Force Tensiometer – K20 is a robust, semi-automatic instrument for the precise measurement of. Using the and as the main tensiometric methods, it produces reliable measurements for the routine quality assurance of your surfactant solutions and interfacial processes.Our K20 measures surface tension and interfacial tension based on the wetting force acting on a measuring probe.
The instrument's precision force sensor and the measuring probes in the form of meticulously produced rings and plates ensure accurate and reproducible results. The density of liquids can also be measured very easily and precisely.
The option of long-life battery operation, the integrated memory and the low weight of the instrument also enable our K20 to be used flexibly on site. Simple, semi-automatic measurementThe simple manual operation of the sample stage and the large, illuminated sample chamber enable the sample to be quickly set up and positioned. When one of the pre-prepared measuring programs is started, the motorized sample stage moves to enable the measurement to be carried out conveniently and accurately. The speed and other measurement parameters can be adapted flexibly to suit. This enables the measuring sequence to be easily optimized for the upper or lower measuring range of surface and interfacial tension. The accuracy of the measurement is enhanced by the magnetically locking windshield which prevents the troublesome effect of air currents. Equipment for flexible measuring conditionsThe optional thermostat jacket for our K20 enables process conditions for temperatures between ‑10 and 130 °C to be simulated exactly.
For example, this enables the addition of surfactant to be optimized for a particular technical process. With dispersions, an integral magnetic stirrer ensures that the sample is uniformly mixed before the measurement is carried out.The measuring results, together with all important parameters and flexibly editable information relating to the measurement, can be transferred to our proven tensiometer software LabDesk. Alternatively, the report containing the results can be output to a printer at the press of a button.
Surface Tension measuring instrumentsSurface tensionis a propertyof the surface of aliquid that allows it to resist an external force. We come across many applications ofSurface Tension in our daily life like the use of detergent, soap,shampoo, creams, branded juice, soft drink, bear, pharmaceutical suspensions, printing, writing,printingetc are some common process, where Surface Tension has an importantrole to play. The formulator needs to use various Surfactants in order to develop a product which meet users expectations and are cost effective. They need to optimizethe quantity of various surfactants in order to minimize/ maximize the Surface tension. There are different methods in use for the measurements of Surface Tension, which can be broadly classified as follows:Static measurements:. Du Nouy Ring Method:The traditional method used to measure the Surface or Interfacial Tension.

Maximumpull exerted on ring bysurface is measured. Wilhelmy Plate Method: A vertical plateof known perimeter is attached to a balance and the force due to wetting is measured. Rod Method:A Pt- Rod is used to measure the surface tension by measuring the change in weight with respect to time due to wetting. Spinning Drop Method:The method is used for low IFT, the diameter of drop within a heavy phase is measured with rotation of both the phases. Pendent Drop Method:Surface and Interfacial Tension canbe measured by this technique, even at elevated temperature and pressure. Geometry of a drop is analyzed optically.Dynamic Method:.
Bubble Pressure Method:A measurement technique for determining Surface tension at short ages, maximum pressure of each bubble is measured. Drop Volume Method:A method for determining interfacial tension as a function of interface age, liquid of one density is pumped into the second liquid of a different density and time between drops produced is measured.
