The theoretical-practical course to become familiar with the lyophilisation process and the freeze-drying equipment, to the point of being able to design a recipe. You will be able to understand and interpret the results through the process graphs, identifying the most common deffects and solving all the problems that may occur during a cycle. Furthermore, you will have been introduced to the equipment's qualification. maintenance and process validation.

This course is led with extensive experience in the specific fields related to the application, the equipment, and the process of lyophilization in different sectors.

The hybrid model that Comser have implemented, gives the possibility to participate in the Workshops from anywhere in the world.

The ideal training to dive into the world of lyophilisation


Lyophilisation is a technique for stabilizing the product by removing the solvent by sublimation. The use of lyophilization within the pharmaceutical industry has increased in order to favor the shelf-life of drugs.

Approximately 50% of biopharmaceutical products are not stable in liquid form and need to be lyophilised. This course offers the opportunity to understand the lyophilisation process using a theoretical-practical approach at our facilities and with our freeze dryers. Professionals from different companies have already attended to the course, exposing their process and equipment problems, creating an atmosphere of debate and networking for all participants.

¿Who is it for?

This Workshop is aimed at people who work in the pharmaceutical, cosmetic, biotechnology or any industry related to the process and the application of freeze-drying. It is designed for all kinds of technicians working in the areas of production, validation, quality, technology, and anyone who wants to improve their knowledge on the freeze-drying process and the freeze drying equipment.
