Superficie in spugna BPW

For environmental surfaces to collect and ship microbial samples.

The Romer Labs Sponge-Stick is a 3″ x 1.5″ (7.5 cm x 3.5 cm) compressed cellulose sponge attached to a quick-release handle, pre-moistened with 10 ml buffer of choice and individually packaged in a sampling bag (Twirl-Tie™). The quick-release handle provides an extra level of convenience and reliability. It is designed to release the sponge into the sample bag after sample collection, allowing only the sponge to be returned to the laboratory. Unnecessary parts that could interfere with sample processing are therefore eliminated.

BPW (Buffered Peptone Water): This is a non-selective pre-enrichment medium that enhances the revival of damaged cells.
LB (Letheen Bouillon): A nutrient-rich medium containing lecithin and Tween 80 as neutralisers. This medium can be used to test the effectiveness of hygiene treatment.
DE (Dey-Engley Neutralising Medium): Neutralises bactericidal and bacteriostatic effects of disinfectants. It contains additional nutrients that promote the recovery and growth of microorganisms.
NB (Neutralisation Buffer): Buffer that neutralises the effects of chlorine and quaternary ammonium compounds. Can be used on disinfected surfaces.
