Sponges and wipes are used to collect samples from surfaces, which are then subjected to microbiological analysis to detect pathogens.
They are supplied with sterile gloves or with bags that act as sterile gloves, helping the operator perform sampling while avoiding cross-contamination.
For sanitized surfaces, sponges and wipes should be paired with solutions containing neutralizing agents.
Sterile wipes
Sterile wipes measuring 25 × 40 cm or 20 × 38 cm are available in various formats:
- dry
- dry combined with tubes containing BPW, MRD, or neutralizing solutions
- pre-moistened with BPW, MRD, or neutralizing solutions
Wipes for sampling disinfected surfaces contain the ISO 18593 – 6887 neutralizing solution, formulated with components that neutralize various disinfectants.
Wipes for sampling carcasses and non-disinfected surfaces use general diluents such as BPW and MRD (ISO 17604 – 6887).
Sterile wipes can be packed in:
- pocket bag
- bag for homogenizer
