By suction operation of a syringe at a bottom of the bacteria collection container, the stripping solution is sucked into the insertion opening, flows out from the distal end opening through the channel, and is filtered through the filter. A medium is supplied to the filter for cultivation. A result of the cultivation is observed, and an evaluation result as to cleanliness is obtained from presence or absence of bacteria. | 08-27-2009 |

A compound or condition is disclosed which comprises a substrate having a surface layer containing functional groups thereon desirably free of silicon linking groups. The functional groups are desirably in the form of a monolayer of a uniformed distribution and of a selected quantity. Various types of microorganism indicators, such as spores, and/or etiological agent indicators are covalently bonded to the surface layer functional groups through a crosslinking reagent and thus form a uniform number and distribution of the microorganism and/or etiological agent indicators. After being subjected to sterilization or other similar disinfecting treatments or processes, along with various articles such as instruments, the indicator can be cultivated to determine the effectiveness of the sterilization, disinfection, etc. treatment or process. | 06-17-2010 |
