Lovibond® hydrosense Legionella Swab (Biofilm) Test Kit (5 Tests)Within a water system Legionella usually grow within biofilm (slime) found on the insides of pipe work, shower heads, cooling tower packing, or water tanks. Bacteria found in the planktonic phase (i.e. suspended in the water itself) are usually an indicator of colonization of the biofilm.
Since a clean water sample does not equate to a clean system (proliferation of Legionella is greater in a biofilm than in water), this kit can be used to pinpoint the contamination in a system or to demonstrate cleanliness of an area after a targeted cleaning.
Use this kit to find Legionella in their breeding ground — this very selective test can detect Legionella even in samples with very high background flora.
With results in 25 minutes, the test allows for immediate understanding and response to the water system conditions. Regular use will increase confidence in your legionella control procedures and reduce risk of outbreaks and litigation!

Net Weight
| Number of tests: | 5 |
| Bacteria Detected: | Legionella pneumophila serogroup 1 |
| Detection Method: | Lateral flow immunochromatographic assay |
| Lower Limit of Detection: | up to 200 CFU per swabbed area |
| Test Volume: | 100 μL (exact volume pipette provided) |
| Suggested Sample Area: | 10 cm2 |
| Test Development Time: | 25 minutes |
| Operator Time: | 1 - 2 minutes |
| Specificity: | Tested against a wide range of waterborne bacteria, including Acinetobacter calcoaceticus, Aeromonas hydrophila subsp. hydrophila, Bacillus subtilis, Burkholderia cepacia, Citrobacter freudii, Citrobacter koseri, Escherichia coli, Enterobacter cloacae, Klebsiella oxytoca, Pseudomonas aeruginosa, Pseudomonas fluorescens, Pseudomonas putida, Pseudomonas stutzeri, Ralstonia pickettii, Raoultella terrigena, Streptococcus pyrogenes, Yersinia ruckeri. No cross reactions observed at concentrations ≤109 CFU/L.
Staphylococcus aureus has been observed to cross react with the test at concentrations >108 CFU/L.
Legionella pneumophila serogroups 4 & 7 cross react with the test at concentrations > 6×109 CFU/L. The test does not react with any other L. pneumophila serogroups or L. species tested. |
| Biocides: | The product has been tested with a range of common biocides and biodispersants used in Legionella control, at their normal maximum operating concentration. Active ingredients tested include: glutaraldehyde, didecyl-dimethylammonium chloride, isolthazoles, ibromonitrilopropionamide, ionic and non-ionic surfactants.The test gives a false positive if used with polymeric biguanide or THPS. |
| Shelf Life: | 18 Months from manufacture (stored at room temp. (<30°C) in original packaging). |
