ROMIL-BiO^™ is a range of solvents of particular interest to molecular biologists and biochemists. Purification methods, although derived from those used for ROMIL-SpS^™ Super Purity Solvents, are finely tuned to match the purity requirements for demanding techniques such as protein sequencing and DNA/peptide synthesis. Indeed, many ROMIL-SpS^™ solvents are also suitable for such applications.
