DIFFERENTIAL SCANNING CALORIMETRY
Brand: TA Instruments
Modelo: DSC Q2000
The DSC Q2000 is a high precision thermal characterization device with a sensitivity of less than 0.2 Mw, with a cell designed for heating and cooling that ensures that the generated data is of superior quality. The operating range temperature is -89 to 400 ° C.
Differential scanning calorimetry (DSC) is a technique that measures the difference between the amount of heat absorbed or released from a sample in relation to a reference, when both are subjected to a temperature controlled program in a given temperature range. The energy absorbed or released by the sample is the product of the thermal transitions experienced by the sample (melting, crystallization, transition of crystalline structures, etc.) during thermal sweeping. Such variations are compensated by the addition or subtraction of an equivalent amount of electrical energy that supplies the heather located in the sample holder. From there the thermogram signal corresponding to the difference between the sample plate signal and the reference plate signal emerges.

CONTACT ANGLE
Uses and applications
Brand: Theta Lite
An instrument designed for measurement of contact angles and free surface energy. It allows measurement of interfacial tension through the hanging drop method and contact angle measurements through the meniscus method.
The contact angle is formed when the drop makes contact with the study surface. The size of the angle between the liquid and solid substances depends on the chemical interaction of the materials on the surface. The less interaction they have, the greater the contact angle is.
Certain characteristics of the surface (eg surface energy) can be determined by the size of the angle. The larger the contact angle is, the harder it is to moisten the solid and less foreign bodies can adhere to the Surface.
