HiEnviro-Sponge™ Stick Hydrated w/10ml Neutralizing Buffer, sterile.
EST004 is standardly pre-hydrated with a clean, efficient Neutralizing Buffer. This solution is engineered specifically to counteract the bactericidal and bacteriostatic effects of common chemical cleaning agents, such as chlorine-based treatments and quaternary ammonium compounds (QACs)
When cleaning residues are left behind on food processing plants or dairy equipment, they can inadvertently kill or stress target bacteria collected during swabbing, giving a false-negative laboratory report. The 10ml chemistry matrix in the EST004 targets these chemical compounds instantly:
• Sodium Thiosulphate: Completely inactivates and neutralizes residual chlorine and iodine-based sanitizers.
• Neutralizing Compound Complex: Destroys the surface activity of quaternary ammonium compounds (QACs).
• Potassium Dihydrogen Phosphate: Acts as an excellent buffering system to protect vulnerable cell membranes from osmotic shock.
This dynamic preserves the biological viability of key pathogenic targets—like E. coli, Salmonella Typhimurium, and Listeria monocytogenes—allowing them to recover and replicate properly once incubate
