Descripción

Application

• Chemical analysis of acoustically levitated drops by Raman spectroscopy.: Innovative use of acoustical levitation combined with Raman spectroscopy to analyze the chemical properties of droplets in a non-contact setup, useful in scenarios where DMSO is used as a solvent ( Tuckermann et al., 2009).

Caution

Fácilmente superenfriado, vuelve a fundir lentamente a temperatura ambiente. Producto solidificado que puede volver a licuarse por calentamiento a temperatura ambiente sin detrimento del producto.
