Products -> MagnaAmp® Biological Indicator

MagnaAmp is a self-contained ampoule biological indicator ampoule for monitoring steam sterilization of liquids in ampoules, large containers, or washer sterilizers. The MagnaAmp biological indicator ampoules contains Geobacillus stearothermophilus spores and a specially-formulated culture medium that turns a dramatic yellow if spores grow.

The MagnaAmp provides easy visual confirmation of sterilization within 48 hours, without the need for difficult and time-consuming laboratory work.

Use

Please follow instructions provided with each box of MagnaAmp biological indicators.

1. Remove MagnaAmp from the refrigerator and allow to stabilize at room temperature, approximately 1 to 2 hours.
2. Place MagnaAmp either inside a large container or next to a container containing a liquid for sterilization.
3. Assure the liquid container containing the MagnaAmp biological indicator is the same size and contains the same volume of liquid as the product containers being sterilized. NOTE: Generally, a minimum of 10 units are placed in each load.
4. Following exposure, remove the MagnaAmp or the container with the MagnaAmp biological indicator and place into a 55-60°C incubator and incubate samples for 48 hours.
5. If the spores survive the sterilization cycle, the culture medium will turn to yellow (positive). If the spores have been killed, the culture medium will remain the original color (purple). NOTE: It is best to read results approximately every 12 to 24 hours. All positive (yellow) samples should be recorded and disposed of immediately. All yellow samples should be autoclaved prior to disposal.
6. Record test results.
7. Autoclave all positive samples prior to disposal.
