JMP2000A interface expansion rheometer 

Brief introduction:

JMP2000A interface expansion rheometer is based on the Langmuir trough method interface expansion viscoelastic properties measurement of special equipment, can be used for oil/water or air/water interface expansion viscoelastic properties measurement, in addition to retain the JM99 way of constant speed in a series of dynamic membrane pressure recorder, also can be used to work in three ways: slightly low frequency oscillation modes, the macroscopic deformation steady way, interface relaxed way. Its new USES include interface expansion modulus, interfacial tension can be phase, the steady-state interface expansion viscosity, interfacial viscosity real part and imaginary part of the frequency spectrum and interface of basic relaxed process measurement and research. The instrument in applied chemistry, biological membrane, liposomes, nonlinear physics, optoelectronics, integrated optics, dilute the active source, LB film, supramolecular configurations, and other fields have a wide range of USES.

Main features:

1. The whole process is controlled by PC computer and lead single machine, has the very good feasibility and repeatability.

2. The master control program is Win98, Win2000 / XP interface, easy operation, standard BMP image file, print, can store data can secondary processing.

3. The tank surface area is large, double slide.

4. High sensitivity, low noise, small vibration, stable walking speed. Leakage is small.
