Mini Spore Strips (2 mm x 10 mm) will fit into small areas of a device where a standard-sized (6mm x 30mm) spore strip cannot be used, such as within a syringe barrel, inside tubing or under a cap.

Mini spore strips are packaged in shelf packs of 100 strips. These products are labelled with a 24 month shelf-life from the date of manufacture. Store strips at room temperature conditions (15 - 30˚ C). Each pack is accompanied by a certificate of analysis. Spore strips are certified for population, purity, and resistance (D value, z value, survival and kill where applicable).

Excelsior mini strips are compliant with ANSI/AAMI/ISO/EN 11138 series of standards and USP where applicable. For availability and lead times of population levels other than 106, please enquire.
