Freeze drying and sterilisation processes R&D Laboratory Sterilisation of Client product in the laboratory’s autoclave Tests in the autoclave can determine the optimum conditions for sterilisation for all types of product: solid, porous, liquid, plastic, and so on. Product formats which usually require an in-depth study are plastic containers with liquid inside. The overpressure exerted by the gas inside the container during sterilisation may permanently deform it so as to render it unusable. The external counter-pressure which needs to be exerted throughout the process to prevent deformation of the container is determined in the laboratory autoclave. This counter-pressure may be exerted with the steam-air mixture or with superheated water. The choice of which system is most appropriate will depend upon the state in which the container is to emerge from the autoclave: dry or wet. The small volume of the autoclave chamber makes it possible to carry out tests with small quantities of containers. The results can then be easily transferred to an industrial scale plant. www.telstar-lifesciences.com 02 309 1111 I Telstar reserves the right to improvements and specifications changes without notice.

Development of freeze drying recipes Expert users may also make use of Telstar’s services to optimise elderly recipes which were designed at a time before present-day analytical methods became available. Telstar makes its Process Laboratory available to you … A preliminary study of the thermal characteristics of the product makes it possible to adjust the working conditions of the freeze dryer in order to increase the sublimation rate without compromising the final quality of the product. This may result in a considerable saving in the cycle time, with a consequent increase in productivity. Current...
