설명

애플리케이션

• 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).

주의사항

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
