The Basics of Bioburden Testing
What is bioburden? Bioburden is the quantity and types of native bacterial and fungal flora present on or in a device, substrate, or chemical (test unit). Bioburden plays a large role in determining what is necessary to achieve sterility, and can impac
The Basics of Medical Device Packaging
When developing a sterile barrier system for medical devices, there are several aspects that need to be considered in choosing packaging and qualifying your sterile barrier system (SBS)
The Importance of Risk Assessment
Due to the all-consuming nature of designing a brand new product, developers are frequently more focused on functionality than risk.
Transfer of Sterilization Dose, Verification Dose or Maximum Acceptable Dose Between Radiation Sources
This document answers many of the FAQs regarding radiation source transfers and addresses possible transfer types and areas for consideration.
Transferring of the Verification Dose from Electron Beam Technology to Photon Technology (Gamma or X-ray)
Background A verification (dose audit) or sterilization dose experiment requires a narrow and specific dose range to be applied to the samples used for tests of sterility as evidence that the routine minimum dose remains appropriate for delivering the
VDmax25 Quarterly Dose Audits: Interpretation of Results
This TechTip provides guidelines on how to interpret the results of a VDmax25 audit
What Are Significant Figures?
Significant figures are numbers that carry a contribution to a measurement and are useful as a rough method to round a final calculation. For more complex systems such as the uncertainty of a dosimetry system, or estimating the bioburden of a product, more accurate methods should be used
