    Environmental Samplers and Swabs

    A range of environmental swabs to assist your requirements. As easy as 1, 2, 3. These ready-to-use kits from Merck for monitoring of difficult to reach areas.

    These Samplers and Swab Test Kits simplify routine microbiological analysis of surfaces for bioburden levels of bacteria, yeast, or mold. This technique eliminates the cumbersome and expensive hardware and materials associated with traditional testing techniques. The Swab enables sampling in areas difficult to reach.

    HPC Sampler

    Contains m-HPC medium for recovery of aerobic bacteria, non-stressed as well as stressed (i.e. partially sanitized or nutritionally starved). Some types of bacteria are slow growers or organisms that were injured from chlorine but not killed.

    Coli-Count™ Sampler – A “Total Count” of coliforms

    Contains a proprietary coliform medium for recovery of coliform organisms.

    Yeast & Mold Sampler

    Contains m-Green medium for recovery of yeast and mold.

    Easy-to-Use:

    • Just add a small sample of liquid to the pre-sterilized sampler or wipe a surface of interest with the swab
    • Results achieved by visual counting of colonies

    Ready-to-Use:

    • Pre-measured dehydrated agar in the sampler
    • Stable at room temperature for storage and for incubation

    HPC Sampler

    Contains m-HPC medium for recovery of aerobic bacteria also stressed bacteria (i.e. partially sanitized or nutritionally starved). An example of when to use this might be to test water that has had chlorine added to it. Dental offices, dialysis offices, and hospital environments. Some types of bacteria are slow growers or organisms that were injured from chlorine but not killed.
