Validation of Reduced Incubation Times (Readout Reliability Data)

The 3‑hour and 48‑hour incubation times have been correlated with a 7‑day incubation period. Sterilized indicators were examined daily for detection of a visual pH color change. The

3‑hour fluorescence change reading and the 48‑hour visual pH color change reading were compared to the 7‑day visual pH color change readings to determine the readout reliability of the indicator. Readout reliability of the Attest™ 1292 rapid readout biological indicator was determined using the sensitivity calculation described below:

Sensitivity = (Number of Growth Positives after 168 hours) – (Number of False Negatives) X 100

Number of Growth Positives after 168 Hours

These data demonstrate that ≥ 97% of the 7‑day (i.e. 168 hours) growth visual positives were detected by fluorescence within 3 hours of incubation and by the visual pH color within 48 hours of incubation. The 3M™ Attest™ 1292 Rapid Readout Biological Indicator therefore meets readout reliability of ≥ 97% for the 3 hour fluorescence results and the 48 hour visual color change results.

1292 specifications

The 3M 1292 is a high-performance adhesive transfer tape that has gained considerable recognition in various industrial and commercial applications. Known for its reliability and versatility, the 3M 1292 is designed to meet the demands of different industries while providing exceptional bonding strength.

One of the main features of the 3M 1292 is its impressive adhesive formulation. This transfer tape utilizes an aggressive acrylic adhesive that provides excellent initial tack and long-term holding power. The adhesive is designed to bond a wide variety of substrates, including metals, plastics, and composites, making it suitable for diverse applications. Its ability to adhere to both smooth and rough surfaces allows for greater flexibility in design and manufacturing processes.

The advanced technologies employed in the production of the 3M 1292 enhance its performance. The tape features a thin transfer film that ensures a clean and precise application. This thin profile minimizes bulk while maintaining strength, allowing for a seamless finish in applications such as signage, displays, and nameplates. Additionally, the transfer tape is engineered to resist temperature fluctuations and various environmental factors, ensuring the integrity of the bond even in challenging conditions.

Another important characteristic of the 3M 1292 is its ease of use. It comes in convenient rolls that can be easily cut to size, enabling users to apply the tape according to their specific needs. The tape's easy-release liner simplifies the application process, allowing for efficient handling during manufacturing or assembly. This user-friendly design contributes to reduced labor costs and enhances productivity in various workflows.

The 3M 1292 is also notable for its durability. The tape is resistant to UV light, moisture, and chemicals, making it suitable for outdoor applications without compromising its adhesion properties. This durability extends the lifespan of bonded products and reduces the need for frequent maintenance or replacement.

In summary, the 3M 1292 adhesive transfer tape stands out due to its aggressive adhesive formulation, advanced production technologies, user-friendly application, and remarkable durability. These features make it a top choice for industries ranging from signage and automotive to electronics and building materials, effectively supporting a multitude of bonding requirements.
