Quantity:

Washer Disinfector

These tests check that the pre-treatment plant supplying the final rinse water (such as softeners, and reverse osmosis units) are working correctly and that there is no bacterial contamination in the rinse water which could contaminate the medical devices.

Each pack contains a 1 x 500ml and 1 x 1 litre sterile bottles and full instructions.  The bottles have additional sodium thiosulphate to neutralise chlorine disinfectant and ensure accurate results.

Our laboratory will test the samples for:-

  • Conductivity
  • Total Hardness
  • Total Viable Count (TVC)

Contact AquaCert at least 24 hours before you fill the bottle so that we can arrange for a courier to collect it from your property.

There is no cost for the courier collection, AquaCert has national contracts with several courier companies to ensure samples are picked up and delivered to the laboratory.

There is an enhanced suite of tests which are undertaken at least every 3 months

The cost of this product includes the following:-

  • Instructions on filling the sample bottle(s).
  • Details on when to contact AquaCert (at least 24 hours before taking the sample) to arrange sample pick-up.
  • A refrigerated courier collection from your selected address to our laboratory.
  • Laboratory analysis.
  • Certificate of analysis.
  • Interpretation of the results and the level of risk (if the sample shows elevated TVC counts or high hardness/conductivity levels).
  • Recommendations on how to reduce the risk.

To conform with UKAS, we must receive the water sample within 24 hours and during that period the sample should be maintained at approx. 4°C – this is why AquaCert only use dedicated couriers with temperature controlled facilities.

In addition to the cost of the test, AquaCert Ltd charge the current postage rate to send the pack out to your selected address.

Water samples are incubated for 72 hours at the laboratory before the final results can be confirmed.

Question

Why can’t we post the sample back to you, couriers must add to the cost of your product.

 

Answer

Laboratories are regularly audited to ensure they meet UKAS standards.  Samples must be marked with the time/date that they were taken and analysis must begin within 48 hours (max). The UK postal service is no longer guaranteed to deliver within this time period. Samples that arrive at the laboratory more than 48 hours after sampling are deemed Non-Compliant and should not be tested.

 

Question

Wouldn’t it be easier to use smaller bottles, other companies just ask for 250ml but AquaCert send out 1 litre bottles.

 

Answer

Yes, it would be a lot easier!

However, the international standard for legionella testing is set out in the document BS EN ISO 11731:2017 Water quality - Enumeration of Legionella.

We don’t take shortcuts, our testing is 100% UKAS accredited and the results will hold up in court.

Taking smaller sample sizes or allowing more than 48 hours transit time is not recommended and the validity of the result  would be challenged if used as evidence in a law court.
