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.

Hydrocarbon levels on swabs should not exceed the negative control NOTE: Using the vapor pressure of ice table is a scientific way to determine an appropriate pressure for freeze drying. User Portal Sign in Register. If you do get stuck do hesitate to ask again. Choosing a freeze dryer depends on the product characteristics as well as many other application-based variables including the container that the product will be dried in, the shelf area or number of ports required to accommodate the valiidation to be dried in each batch, the total volume of ice to be condensed and whether there are any organic solvents.

Flowers Animals Water damaged books and documents.

Session 2 of 3 Part Series: Lyophilization Process Validation – Part 1 – SP Scientific

The collapse temperature of amorphous products is typically a few degrees warmer than its glass transition temperature. I would suggest the following. She is responsible for all Quality aspects of clinical manufacturing, and is the primary Regulatory contact for the company.

Our people make the difference. In a clean room environment vlidation very few particulates for ice nucleation, there is a significantly greater amount of super-cooling.

Basic Principles of Freeze Drying

Request a Quote Interested in learning more about our products? This is critical to product quality. A freeze dryer consists of three main components: During primary drying, the system pressure and the shelf temperature are vvalidation and controlled in combination to yield the appropriate product temperature. The resources are truly invaluable and appreciated.


System vacuum may be continued at the same level used during primary drying; lower vacuum levels will not improve secondary drying times. These emails are sent vallidation scammers. SP Vslidation associates and distributors look forward to helping you reach your goals. Exhibit Why Exhibit U. The dry product is much more stable than a solution.

SP Scientific is constantly striving for superior service and quality. Lyophilization Process Validation-Part 1. Loss of weight from a weighed amount of water in trays is not less than the stated capacity of the condenser. Do not include the drain in the average temperature calculation.

Regional sales associates, Distributors and service technicians are located throughout the world. In this VP, document how and why you are separating and scoping tasks.

All vials are stoppered No vials are damaged.

It is OK if the thermocouple touches the bottom of the container. Knowledge of cGMP and regulatory guidances concerning validation is desirable.

Upon completion of this course, you will be able to: 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. Enter all this into your URS as the criteria that the validation task has to verify. Karen has over 20 years experience in pharmaceutical manufacturing that includes lyophilization and validation. Barb Berglund has been working in the pharmaceutical industry, specifically with sterile parenteral dugs, for over 15 years.

Statements claiming to offer our attendee lists are fraudulent. Laboratory pilot-sized shelf freeze dryers are often used to develop a cycle to be used for process scale-up to a larger production sized unit.

For sterilize-in-place SIP cycles, it is necessary to reproducibly demonstrate the ability to maintain the required temperatures, generate sufficient lethality during the cycle and reduce biological indicator populations to meet the customer requirements and industry standards. Ellab offers a battery package that, when paired with an appropriate logger, can operate at low temperatures.


Understanding the physical properties of materials that are freeze-dried is a key part in developing a successful lyophilization process. OVERVIEW Freeze drying is the removal of ice or other frozen solvents from a material through the process of sublimation and the removal of bound water molecules through the process of desorption.

In addition, the participant will gain an understanding of the basic principles of lyophilization and the techniques utilized in evaluation of lyophilized materials. Because shelf contact is often inconsistent, convective heat transfer can help promote uniform product drying.

As shown below on the phase diagram for water, low pressures are required for sublimation to take place. You need to break down the tasks, as trying to handle them all in one valieation would be messy and difficult.

The SKY option can be advantageous if transmission distances are not too far. The difference in particulates can greatly affect product freezing and ice crystal size. Depending on the application, moisture content in fully dried products is typically between 0. Karen Bossert discusses process calidation part 1. Frozen vlidation can be categorized as either crystalline or amorphous glass in structure.

If an event must be cancelled, registrants will be notified by PDA as soon as possible and will receive a full refund. Annealing has the added advantage of larger crystal growth and corresponding shorter drying times.

Stoppering All vials are stoppered No vials are damaged. Process A freeze dryer consists of three main components: There should at least be a weight or volume change. Primary drying is a top-down process with a well-defined sublimation front moving through the product as it dries.
