Lyophilisation

Lyophilisation (freeze-drying) is a dehydration process used to preserve peptides by freezing the solution, reducing the surrounding pressure, and then removing the ice by sublimation (direct conversion from solid to gas phase). The resulting lyophilised powder is highly stable, with shelf lives of several years when stored properly, because the removal of water prevents hydrolytic degradation and microbial growth. Traditional peptide research relies on lyophilised vials that require manual reconstitution with bacteriostatic water before each use, introducing variables in concentration accuracy and contamination risk. ORYN's pre-mixed peptide pen system eliminates the reconstitution step entirely by providing a stabilised liquid formulation in a sealed cartridge. Both approaches offer the convenience of ready-to-use administration while maintaining pharmaceutical-grade stability.
