Bio-Mark, used for environmental monitoring and sterility testing on the surfaces of production equipment. This swab series integrates the necessary swab and diluent for inspection into one unit, enhancing flexibility in use. Additionally, it features a dispensing function, allowing the test solution to be injected into petri dishes and test tubes without the need for a pipette. This reduces inspection costs and minimizes the risk of recontamination from additional inspection tools. All packaging is sterile.
