Advanced Formulation for Sample Integrity

PR1MA™ Stretch is composed of a proprietary blend of paraffin and polyolefins, engineered to provide a flexible moisture barrier that protects delicate samples from contamination and evaporation. While delivering an airtight seal, it still permits the exchange of essential gases like oxygen (O), carbon dioxide (CO), and water vapor (HO)—ideal for cell culture and biological sample storage.
