MagnaAmp & SterilAmp II Biological Indicators for Liquid Loads
MagnaAmp & SterilAmp II are self-contained Biological Indicator (BI) ampoules for monitoring steam sterilization of liquids, such as media. You can choose between two spore populations (Log 5 or Log 6) based on your local regulatory requirements.
Use MagnaAmp in liquid containers with greater than 10 mL and SterilAmp II when liquid quantities are less than 10 mL. Both biological indicator ampoules contain G. stearothermophilus spores and a specially-formulated culture medium that turns a dramatic yellow if spores grow. MagnaAmp and SterilAmp provide easy visual confirmation of sterilization within 48 hours, without the need for difficult and time-consuming laboratory work.
Liquid Volumes of 10 mLs or more choose: MagnaAmp
Liquid Volumes of LESS than 10 mLs choose: SterilAmp II

INSTRUCTIONS
(Included in package)
Sterilization:
1. The MagnaAmp™ should be suspended in the geometric center of the liquid mass, approximately 1/3 of the liquid height off the bottom of the container. The SterilAmp™ II is just placed inside the liquid container to be sterilized. Package or seal as usual. AAMI recommends a minimum of 10 Biological Indicators (BIs) per cycle.
2. Locate test samples in areas of the load considered most difficult to sterilize or in convenient areas that have been validated. Identify test samples as to location in sterilizer.
3. After sterilizing, follow the test procedure.
Test Procedure:
MagnaAmp and SterilAmp II are fully self-contained BIs which do not require subculture.
Procedure:
a. The ampoule may be left in the sterilized container or transferred to a rack or container which allows visual observation during incubation.
b. Incubate ampoule for 48 hours at 55-60°C. (Optional Model 1501 Incubator for MagnaAmp Ampoules)
c. The 48 hour incubation meets the criteria established in the FDA protocol for validation of reduced incubation time (RIT). Incubate for 72 hours when monitoring SSM-150 medical waste treatment cycles.
d. Observe daily for growth.
Yellow = growth = non-sterile
Purple = no growth = sterile
Ampoule should show "no growth" if sterilization has been achieved.
If color change occurs in ampoule cultures, it indicates that the spores have survived the sterilization process and are non-sterile.
Positive Controls: At least one positive control should be included in each test series. Incubate a non-sterilized ampoule with test series. Color change from purple to yellow indicates that the medium possesses suitable growth promoting qualities and that the ampoule contains viable spores. If positive control does not grow, do not use the units from that package. Contact us.
Storage and Disposal:
1. Refrigerate at 2 – 8°C. Protect from light.
2. Incinerate or autoclave at 121°C for not less than 30 minutes.
3. MagnaAmp and SterilAmp II biological indicators have a shelf life which is clearly designated on each package. Rotate your stock accordingly.
NOTE: Do not use after expiration date printed on package. Dispose of expired indicators by autoclaving at 121°C for not less than 30 minutes.
