Reconstitution diluents and bench ancillaries for lyophilized-peptide workflows — bacteriostatic water, sterile water for injection, isotonic saline, 0.6% acetic-acid water, and glacial acetic acid. The supporting consumables a lab pairs with a reference standard once it leaves the freezer.
Who sources this class & for what
Solvents and ancillaries are the bench-support consumables a lab pairs with a reference standard once it leaves the freezer — bacteriostatic and sterile water, isotonic saline, 0.6% acetic-acid water, and glacial acetic acid for in-house diluent prep. These are diluents and process auxiliaries rather than research targets, so the documentation is diluent / solvent-grade (component identity, sterility, endotoxin, pH / osmolality, pharmacopeia monograph) rather than the peptide HPLC + MS + sequence packet. Diluent selection follows the peptide's stability profile: acidic-pH-requiring proteins use the acetic-acid water; preservative-incompatible peptides use sterile water; preservative-compatible peptides for multi-use vials use BAC water.
