설명

일반 설명

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

애플리케이션

Dimethyl sulfoxide is used as a solvent:

• To dissolve the substrate and to dilute fluorogenic substrate.
• To permeabilize V. natriegens or E coli cell.

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.

규격

Saturation Concentration in Air: 8.0 g/m3 (20 °C)
