Design Verification is the next required step in the design process. Verification is literally an examination of evidence to prove the predetermined requirements have been met. This is an exercise done on paper, where you take all the design inputs (specifications, regulations, knowledge from previous designs, and any information required for proper function of the…

The next requirement for the design process is the Design Review. This is set up as a milestone(s) during product development, and is used to evaluate the design in relation to the previously identified requirements. These checks will help to identify issues before committing to further work on the product. Per the FDAs definition in…

The next procedure required for the Design process is related to Design Output. Design Outputs are the results of the design efforts, typically coming together as a product specification. During the Design Input process, or immediately following, these Design Output documents need to be prepared: Component and raw material specifications, product/process specifications, drawings, software code,…

As of Dec. 31, 2014, the United States Environmental Protection Agency Clean Air Act will prohibit the sale and use of HCFC-based (hydrochlorofluorocarbon) products in the US, and that will include Oxyfume ethylene oxide (EtO) sterilant blends such as Oxyfume 2000, often used by BI manufacturers for assessing BI EtO D-value label claims. To see how this change impacts the BI manufacturing community, read the complete, peer-reviewed article by signing up for Mesa’s Spore News newsletter today.
Can’t find an off-the-shelf biological indicator that’s right for your sterilization process? Our engineers can work with you to design a custom indicator that will work for even the most challenging applications.
According to the International Organization for Standardization (ISO), a biological indicator is a test system containing viable microorganisms providing a defined resistance to a specified sterilization process. Biological Indicators (BIs) have been in use for several decades and are used in hospitals, food processing, tattoo parlors, dentist offices, pharmaceutical and medical device manufacturing, ambulatory surgical centers and anywhere else where validation and verification of an adequate sterilization cycle is required.
BIs come in many different shapes, sizes and configurations. Spore Strips have been in use for several decades and are still very widely used for a variety of sterilization processes. Self-Contained Biological Indicators (SCBIs) have become much more popular over the past 30 years, as they are more user friendly and often offer reduced incubation times. For situations where typical BIs are not appropriate, suspensions are widely used to directly inoculate product/substances and Mesa’s line of industrial use BIs are available to test the lethality of a sterilization cycle in a very specific area of a product or load.
Steam sterilization is the most popular type of sterilization and Mesa offers several different indicators to monitor the wide variety of items that are sterilized in steam. The variety of items being monitored is what has predicated the development of the variety of indicators that Mesa offers. Porous items (towels, hard goods, etc…) are easily monitored with Spore Strips while the use of test packs with SCBIs is ever increasing. Ampoule indicators are best utilized in liquid loads sterilization (bottles, media, etc…) and offer a variety of sizes for flexibility. Mesa also offers a complete line of Chemical Indicators including Class 5 (Integrators) and Class 6 (Emulators), Bowie-Dick type test packs and more.
Ethylene Oxide sterilization is one of the most common sterilization methods for medical devices including specialty device kits used for specific surgical procedures. EO sterilization is most useful due to the fact that it uses a reduced amount of heat and is therefore safe for heat sensitive materials and devices. Because of this, a completely separate type of biological indicator must be used for sterility assurance testing and monitoring. Utilizing a different species than our steam products, Mesa’s offers EO BIs as spore strips, SCBIs, test packs, suspensions, custom BIs and chemical indicators as well.
Dry heat sterilization requires longer cycle times, higher temperatures and specialty biological indicators. Spore strips can be used in dry heat sterilization however as temperatures rise, charring becomes an issue and the indicator itself burns. Mesa offers a couple alternatives to spore strips with stainless steel discs and with its product DriAmp. DriAmp is an ampoule containing sand inoculated with spores which can withstand extreme temperatures. Additionally, Mesa offers chemical indicator labels for use with this process.
Mesa has created a host of biological indicators for specialty sterilization processes including hydrogen peroxide (H2O2), chlorine dioxide (ClO2), low-temperature steam with formaldehyde (LTSF), gamma irradiation, propylene oxide and more.
