This short article is an introduction to the basic selection of sterilization autoclaves. It defines this type of equipment, summarizes the varieties available and discuss the preliminary problems to cope with in specification and design of sterilization autoclaves.
Several reports on degradation of Hyaluronic Acid (HA) involving microwaves, UV or γ-rays have been published. Rheological studies also show that Hyaluronic Acid (HA) solutions degrade at high temperature: viscosity of the solutions decreases in time as a function of temperature. Therefore, the thermal sterilization treatment of Hyaluronic Acid (HA) solutions represents a great challenge. […]
Prefilled syringes offer several advantages over traditional packaging in vials. For example, microbial contamination is minimized due to less manipulation.This presentation discusses a method for sterilizing PFSs through a moist heat process, the most common and approved method used by pharmaceutical facilities for this type of products. The main issues to consider while sterilizing PFSs […]
This article is a technical support to the practice of autoclaving aqueous solutions in sealed containers. Two “classical” scientific contributions on the matter are due to Beck and to M. A. Joyce & J. W. Lorenz which are referred in the article. In this article, metric units (abs bar or abs mbar) are used for […]
This article is intended as a basic introduction on feasibility and risks of autoclaving aqueous solutions in sealed containers. Another article, Aqueous solutions in sealed containers: internal pressure under autoclaving, provides a technical approach to the matter. The feasibility and the level of risk of autoclaving sealed containers of liquid solutions under pure saturated steam […]
The purpose of this Fedegari Technical Note, firstly distributed in 1988 and perseveringly revised, is to clarify the nature of F0 and its related parameters (D, z, PNSU/SAL), and to explain their use and limits for the setting, adjustment, control and validation of moist-heat sterilization processes. The F0 algorithm was first introduced in 1968 in […]
A case study of hydrogen peroxide penetration through the load packaging: a customer required support for «A Package Integrity Verification» which involved all the samples and consumables inside the Sterility Test Isolator.
Aseptic processing is considered by many in this industry to be among the more difficult activities to execute properly. The number of variables that affect the safety of sterile products manufactured aseptically is substantial. In the design and operation of an aseptic production facility, it is essential that risk to the patient be minimized. This […]
