Attest™ Steam Biological Indicator 1262 - 48 Hours
Self-Contained BI - 121°C Gravity and 132°C Vacuum-Assisted Steam - Visual Readout - Box of 100

The Attest™ Steam Biological Indicator 1262 is a self-contained biological indicator for monitoring vacuum-assisted steam sterilizers at 132°C and gravity displacement steam sterilizers at 121°C. Attest is a Solventum brand, formerly 3M, and the 1262 was previously sold as the 3M Attest Steam Biological Indicator 1262. Each indicator contains a spore strip and a crushable vial of growth media. After sterilization, the vial is crushed to bring the media into contact with the processed spore strip, and the indicator is then incubated for 48 hours for a visual colour change readout.

A colour change of the media to yellow indicates surviving spores and a positive result. The spore population is designed to exceed average instrument bioburden, and the optimized media is formulated to promote spore growth. A chemical process indicator on the label changes from rose to brown after processing. The 1262 is compatible with the Attest Biological Monitoring System 116 incubator. It is not intended for monitoring dry heat, chemical vapour (such as the MDT Harvey Chemiclave) or ethylene oxide (EO) sterilization processes. Each box contains 100 biological indicators.

Frequently Asked Questions

Is the Attest 1262 a 3M product?
Attest was previously a 3M brand. It is now part of Solventum, and the 1262 was formerly sold as the 3M Attest Steam Biological Indicator 1262.

What sterilization cycles is the Attest 1262 used for?
The 1262 is designed for vacuum-assisted steam sterilizers at 132°C and gravity displacement steam sterilizers at 121°C. Refer to the IFU to confirm applicable cycles.

How is the Attest 1262 activated?
After sterilization, the media vial is crushed so the growth media comes into contact with the processed spore strip. The indicator is then incubated.

How long does the Attest 1262 take to give a result?
The 1262 is incubated for 48 hours for a visual colour change readout.

How do you read an Attest 1262 result?
A colour change of the media to yellow indicates surviving spores and a positive result. Refer to the IFU for full result interpretation instructions.

Which incubator works with the Attest 1262?
The 1262 is compatible with the Attest Biological Monitoring System 116, which incubates the 1262 for 48 hours.

Can the Attest 1262 be used for dry heat, chemical vapour or EO sterilization?
No. The 1262 should not be used to monitor dry heat, chemical vapour (such as the MDT Harvey Chemiclave) or ethylene oxide sterilization processes.

What is the difference between the Attest 1262 and the Attest 3 hour rapid steam indicator?
Both are for 121°C gravity displacement and 132°C vacuum-assisted steam cycles. The 1262 gives a visual colour change result in 48 hours in the Attest 116 incubator. The 3 hour rapid indicator gives a fluorescent result in 3 hours in the Attest Auto-reader 390.

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