RC2 spectroscopic ellipsometer equipped with a Linkham heating and cooling stage, allowing us to characterize the temperature-dependent optical properties of thin films.

• Wavelength: ​210-1690 nm

• Angles: 45°-90°

• Temperature: -196°C to 600°C

Gamry The Interface 1010E is a general-purpose electrochemical workstation that can perform a variety of electrochemical measurements, including electrochemical impedance techniques.

We have multiple vacuum ovens which are used to anneal polymer samples.

Cypher ES AFM offers the best resolution and environmental control system on the market. As the main research equipment in the lab, we use AFM to measure soft matter at various interfaces.

• Cooling and heating stage

• Liquid imaging

• KPFM

• Perfusion control

• Environmental control

• Force-curve measurement

• AM-FM

Metro Toledo balance.

Tensiometer in our lab is used to measure the interfacial tension between two media, such as water-oil, and water-air. It also allows us to measure the surface energy of various solid substrates, such as chemically modified si-substrates.
