TX500C spinning drop interfacial tensiometer

Specifications Basic type of spinning drop interfacial tensiometer

independently operated or controlled by software

build-in heating system

Spinning drop interfacial tensiometer model TX500C is entry-level and basic type from USA KINO, which adopts such technologies as removable and both-ends-fixed sample tube sampling mode (RBSM), full-self-sealed quartz glass tube (FSGT) and build-in heating system. The instrument can be independently controlled via control panel or controlled by software, which are both simple and comfortable to operate. It is used to measure interface tension down to 10-6mN/m for analysis of dynamic interface tension, interface rheology and interfacial viscosity (oscillating drop method), surface elasticity, relaxation study, etc. It can be applied in fields of personal care product, tertiary oil recovery, micro emulsion, surfactant and more. Standard spinning drop interfacial tensiometer-TX500C is a basic and classical interface chemistry analytical instrument from USA KINO, consisting of removable rotation sample tube and build-in full-surface radiator heating system of aluminum alloy, etc. The instrument can be independently controlled via control panel or controlled by software, which enables both simple and comfortable to operate. Patent removable and both-ends-fixed sample tube sampling mode (RBSM)(1) Sampling mode with sample tube removable enables easier dosing and easier rinse of sample tube. (2) Brand new patent technology of quartz glass tube with both ends opening, no extra bubble formed and easier to dosing and rinse (3) Sample tube fixed of both ends in the spindle guarantees more stable and less rocking. Build in heating systemSimply equipped gas-thermal temperature control system and full-surface radiator heating mode can be used to heat sample without any other temperature control device, which is more suitable for oil field operators. DC motor with PID control system for more precise, smooth and stableControl port of RS232 and USB2.0 with better compatibility. Illumination-adjustable cold LED light sourceHigh brightness LED guarantees clearer and sharper drop edge, especially for analysis of muddy samples. Sample tube levelness control mechanism used of upgraded rotation stageBy control levelness of high speed rotation chamber and vision system, it easily control of traversing speed of droplet during ultra-low interface tension measurement. World-leading interface tension analytical system-CAST4.0 with comfortable and professional design(1) Automatic dynamic interface tension analysis. CAST4.0 will implement capture, image storage, calculation and display interface tension automatically at the touch of your finger, effectively avoiding errors caused by human. Furthermore, interface tension varying with time, rotating speed and temperature can also be measured, real-time displayed and exported to Excel. (2) Interface tension calculation method based on distance between two boundary lines rather than two points enables more precise result. (3) Humanized software design and database management -Standard magnification calibration mode enables software automatically search magnification once zoom of lens is determined. -Wizard design of standard windows for various measurement operators. (4) Database management: -Query and modifying historical data at any time. -One-to-one correspondence between data and image; Double clicking picture to modify measured value; more convenient to query and retrieve data. -Measured data is Excel exportable for you to create your measurement report conveniently. -Secondary modification of eigenvalue: The software will record all your operation traces for you to check the measured data to avoid errors caused by human.        Technical Specifications
