Ideal as a frozen storage syringe

An increasing number of drugs require frozen conditions to keep them stable over the entire supply chain, from filling the drug up to the drug administration at the patient. Next to mRNA-based therapies,  also viral vectors (AAV), cell and gene therapy, chemotherapy drugs and many cryogenic stored drugs, bring new ways of therapy but also have demanding needs when it comes to their drug containment and delivery. SCHOTT TOPPAC® freeze offer a stable solution, even in deep-cold temperatures down to -100°C. 

Improved specifications and full data package

Made of high-quality, inert COC material, the SCHOTT TOPPAC® freeze plastic syringes come with an extensive data package for the entire syringe performance for the intended use in low temperatures. An improved quality control and specifications for critical quality attributes further support assuring that this drug containment and delivery solution is suitable for filling, transporting and storing your drug properly, no matter if it is frozen or thawed. Being a partner of choice in the field of mRNA-based therapeutics benefits your project. Our extensive experience in this field helps you with overcoming different kind of challenges that you might have with packaging your drug in deep-cold temperatures.
