Legionella Swab Kit

Rapid Legionella detection for effective water system monitoring.


The DTK Legionella Swab Kit provides a practical solution for detecting Legionella bacteria on water system surfaces, delivering results in as little as 25 minutes.


Designed for direct testing of biofilm and surface contamination, the kit helps users identify potential areas of Legionella activity that may not be detected through water sampling alone.


With straightforward operation and rapid visual results, the Legionella Swab Kit supports water treatment professionals in investigating contamination and assessing the effectiveness of Legionella control measures.

Rapid Legionella Detection

Effective Legionella monitoring requires an understanding of potential contamination within water systems, particularly in areas where bacterial growth and biofilm formation may occur.


The DTK Legionella Swab Kit provides results in as little as 25 minutes, allowing engineers and water treatment professionals to investigate potential contamination without waiting for conventional culture results.


This rapid testing capability provides useful information when assessing system conditions, identifying areas requiring further investigation and supporting timely water management decisions.

Testing Where Bacteria Develop

Legionella bacteria can colonise biofilm found on internal water system surfaces, including pipework, shower heads, storage tanks and cooling tower components.


The DTK Legionella Swab Kit allows users to collect samples directly from these surfaces, helping identify potential contamination that may not be apparent from testing water samples alone.


By targeting areas where biofilm may develop, the kit provides additional information to support routine monitoring and the investigation of potential Legionella contamination within water systems.

Suitable for Multiple Applications

The DTK Legionella Swab Kit is suitable for monitoring a variety of commercial, industrial and building water systems where Legionella contamination may present a concern.


Applications include cooling towers, water storage systems, showers, plumbing installations and other building water systems where regular inspection and microbiological monitoring are required.


This versatility makes the kit a practical addition to Legionella risk management programmes, supporting targeted investigations and checks following cleaning or treatment activities.

Designed for Straightforward Testing

The DTK Legionella Swab Kit provides a convenient approach to collecting and analysing surface samples, making it suitable for engineers and water treatment professionals carrying out on-site investigations.


Its selective testing method is designed to detect Legionella in samples containing high levels of background bacterial activity, helping users assess potentially contaminated surfaces.


With five tests supplied per kit and a straightforward testing procedure, the system provides a practical option for targeted monitoring across different sampling locations.

Supporting Effective Legionella Control

Regular monitoring and investigation of potential contamination points are important elements of effective Legionella risk management and water system maintenance.


By combining rapid detection with direct surface sampling, the DTK Legionella Swab Kit provides additional information to help operators assess system conditions and evaluate the effectiveness of control procedures.


This makes the kit a useful supplementary tool for Legionella monitoring, supporting informed maintenance decisions and ongoing water hygiene management across commercial and industrial water systems.
