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, which help the operator perform sampling while avoiding cross-contamination.
For sanitized surfaces, sponges and wipes should be paired with solutions containing neutralizing agents.
Sterile sponges
Sterile sponges measuring 6 × 8 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
Sponges for sampling disinfected surfaces feature the ISO 18593 – 6887 neutralizing solution, formulated with components that neutralize various disinfectants.
Sponges for sampling carcasses and non-disinfected surfaces use general diluents such as BPW and MRD (ISO 17604 – 6887). Packaging of sterile sponges
Sterile sponges can be packed in:
- glove bag
- pocket bag
- zip bag with label
