Quanta S Steam Sterilizable Freeze Dryers (SIP)

Freeze Drying Pharmaceuticals & Biotech Products

Depending on their use, there are a number of different freeze drying specifications to consider. If a lyophilizer is to be used in the pharmaceutical or biotech industries it is likely that sterilization between freeze drying runs is necessary.

Sterilization for Lyophilization of Biopharmaceuticals

Steam sterilization (SIP) is the most common form of sterilization in production lyophilizers. Steam sterilizable freeze dryers require a number of special design considerations. First, steam sterilizable freeze dryers have to be capable of maintaining a full vacuum. Secondly, they must be able to maintain high temperature and high pressures. With this two requirements in mind, Millrock Technology provides two design options: cylindrical or rectangular chambers so you can select the best fit, price and performance requirements for your application.
