Attest™ Steam Biological Indicator 1261 - 24 Hours
Self-Contained BI - 132°C Gravity Displacement Steam - Visual Readout - Blue Cap - Box of 100

The Attest™ Steam Biological Indicator 1261 is a self-contained biological indicator for monitoring gravity displacement steam sterilization cycles at 132°C (270°F). Attest is a Solventum brand, formerly 3M, and the 1261 was previously sold as the 3M Attest Steam Biological Indicator 1261. Each indicator contains a Geobacillus stearothermophilus spore strip and a glass ampoule of growth media with a pH indicator dye.

After incubation, the 1261 gives a visual readout in 24 hours. A colour change of the media from purple to yellow indicates spore growth and a positive result. A built-in chemical process indicator changes from rose to brown or black after processing, and a blue colour-coded cap makes the indicator easy to identify. The 1261 is compatible with the Attest Biological Monitoring System 116 incubator and suits hospitals, clinics and sterile processing departments. Each box contains 100 biological indicators.

Frequently Asked Questions

Is the Attest 1261 a 3M product?
Attest was previously a 3M brand. It is now part of Solventum, and the 1261 was formerly sold as the 3M Attest Steam Biological Indicator 1261.

What sterilization cycles is the Attest 1261 used for?
The 1261 is designed for gravity displacement steam sterilization cycles at 132°C (270°F). Refer to the IFU to confirm applicable cycles.

How long does the Attest 1261 take to give a result?
The 1261 gives a visual readout in 24 hours.

How do you read an Attest 1261 result?
A colour change of the media from purple to yellow indicates spore growth and a positive result. Refer to the IFU for full result interpretation instructions.

Which incubator works with the Attest 1261?
The 1261 is compatible with the Attest Biological Monitoring System 116, which provides results in 24 hours for the 1261.

What is the difference between the Attest 1261 and the Attest 1262?
The 1261 is for 132°C gravity displacement cycles and gives a result in 24 hours. The 1262 is for 121°C gravity displacement and 132°C vacuum-assisted cycles and gives a result in 48 hours. Both are read in the Attest 116 incubator.

Which Attest blue cap indicator should I choose?
Attest offers three blue cap indicators for 132°C gravity displacement steam cycles, and the right one depends on your incubator. The 1261 gives a visual result in 24 hours in the Attest 116 incubator. The 1 hour rapid indicator gives a fluorescent result in the Attest Auto-reader 390. The 1491 super rapid indicator gives a fluorescent result in 24 minutes in the Attest Auto-reader 490 or 490M.

How many biological indicators are in a box?
Each box contains 100 biological indicators.
