This course is designed to give participants an understanding of the requirements for qualification of a lyophilizer and validation of lyophilization processes. Since lyophilizer sterilization and sterilization of the nitrogen system used to backfill require separate validation, media fills should primarily validate the filling, . With Lyophilizers and Freeze Dryer validation, it is essential to verify that the system can meet and control to the different temperature.

Lyophilization and freeze drying are terms that are used interchangeably depending on the industry and location where the drying is taking place.

Without knowing the critical temperature of the product, a trial and error approach is required to determine appropriate primary drying temperatures. During chamber ballasting air is drawn in to chamber to equaliser pressures before unloading cabinet. The refrigeration system can also be employed to cool shelves in the product chamber for the freezing of the product.

At mid-cycle, the pressure and average temperature of the chamber indicate that the steam is saturated. Request a Quote Interested in learning more about our products? This allows the vials to rest directly on the shelf and increases the heat transfer to the product. There are essentially two categories of freeze-dryers: SP Scientific service professionals offer your organization a depth of expertise that is truly unique to our selected industries and markets.

Due to the fact that maintaining a high vacuum is essential for all lyophilization processes, the use of wireless loggers is highly recommended. User Portal Sign in Register. Who Should Attend Personnel from all levels involved in manufacturing, validation, and quality aspects of the lyophilization process will benefit from this course.

View recent webinars on ” Techniques for Enhancing Visualization of Lyophilization Cakes “; the three-part series on ” Lyophilization Validation: When the product temperature equals the shelf temperature, it can be inferred that primary drying is complete.


Operational Qualification In addition to the common requirements outlined in the “General” section, the OQ protocol will outline valldation following tests. Exhibitor Standard Lyophhilizer Clause. Freeze drying occurs extremely slowly at these cold product temperatures.

Additional primary drying endpoint determination tools are available on larger freeze dryers equipped with advanced process control systems.

Secondary drying rates are dependant on the product temperature. Purified Water System IQ. It is recommended that Ellab sensors and probes are sent in at validatiob once a year for factory calibration which includes a traceable calibration certificate. During the SIP cycle: Please arrive at your course location approximately thirty minutes before the start of the course to sign in. Request a Quote Interested in learning more about our products?

Basic Principles of Freeze Drying

Please be sure to bring your confirmation letter as proof of registration. Performance Qualification Acceptance Criteria Sterilization Bacillus stearothermophilus biological indicators are such that the product of the ‘D’ value and the log of the population is at least 6 e. During annealing, the product temperature is cycled for example: Product is either pre-loaded into vials which are then transferred to the shelf or it is loaded in bulk form directly onto a product tray.

The main challenges associated with validation freeze dryers are the low temperatures and the low pressures present. She is responsible for all Quality aspects of clinical manufacturing, and is the primary Regulatory contact for the company.

The ballasting valve admits plant room air – unless it has been specially piped back to only admit room quality air. Sublimation in the freeze drying process can be described simply as: Her experience includes her current role as a Quality Partner as well as strategic leadership roles in the laboratory, project management, and clinical trial manufacturing. More than a scientific equipment supplier, SP Scientific represents brands that distinguish themselves by being able to more thoroughly assist customers in matching equipment to particular application needs.


Loss of weight from a weighed amount of water in trays is not less than the stated capacity of the condenser.

With simple manifold freeze dryers, the product is placed in a vial or flask depending on quantity, and then frozen in a separate piece of equipment.

Validation of lyophilizer – GOOD VALIDATION PRACTICE (cGVP) – Learnaboutgmp Community

Usually the low temperatures can make it difficult for data loggers to function but. All vials are stoppered No vials are damaged. In session two of the three part series Lyophilization Validation: Hydrocarbon levels on swabs should not exceed the negative control NOTE: Stoppering arms valivation be verified as acting uniformly on all product containers.

When the Pirani pressure lyophilzer decreases and approaches the true pressure reading of the capacitance manometer, little or no water vapor is present and it can be concluded that primary drying is complete.

The resources are truly invaluable and appreciated.

In most cases, the more dry the product, the longer its shelf life will be. When the super-cooled lyophiliaer finally freezes, it happens extremely quickly resulting in smaller ice calidation. Dec 07 – Dec 08, Condenser cooling rates are for information only. Each specific product or formulation that is lyophilized requires the development of a freeze drying process that is based on the unique characteristics of the product, the amount of product and the container used. It is best not to freeze a large block of sample in the bottom of a flask because the sample will be too thick for efficient water removal.

The benefit of this container is that the product can be easily reconstituted by simply adding liquid.
