Sterile For environmental surfaces to collect and ship microbial samples. All the advantages at a glance: 3″ x 1.5″ (7.5 x 3.5 cm) biocide-free cellulose sponge Unique, quick sponge-release handle for fast and convenient sponge release Thumb stop in-handle included to avoid accidental sponge contact No gloves needed for different sampling sites Perfectly suited to sample in gaps, drains and pipes Dry or pre-moistened with 10 ml buffer Bags can be opened easily with attached pull tabs Label area for sample identification Irradiated for proven sterility Directions for use 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. Application 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. Sponge-Stick SurfACE™ BPW ISO 18593
