Dip Slides

WHAT IS A DIPSLIDE or biopaddle?

A dip  slide (also called a Biopaddle) is a tool for testing the microbial content of liquids. It consists of a plastic  carrier bearing a sterile culture medium which can be dipped in the  liquid to be sampled. It is then incubated to allow microbial  growth.  The resulting microbial colonies are estimated by reference  to a visual chart.

Dipslides are the most  common method of measuring and monitoring microbial activity within  many systems and commonly cooling systems.

Dipslides are supplied in boxes of 10 or 20 and come complete with instructions and a colour count chart which is used to determine the concentration of aerobic  activity.

DIPSLIDE(S)

Dipslides are used to monitor the general activity of aerobic bacteria. All  dip slides should be incubated at 30^oC for 48 hours to  obtain a true result.  Dip Slides are commonly used for the detection  of slime forming bacteria in cooling & industrial water systems.

Dipslides are dipped into the water sample and incubated for 48 hours.  Any bacteria in the sample water  will grow and form colonies.  When compared with the reference chart  supplied on the dip-slide box it is possible determine the number of  bacteria in the sample.  Once the dipslide has been placed in contact  with the sample water or surface it should be returned and secured in  its container for incubation for 48 hours normally 30^oC.   For continuity it is important to ensure that the incubation period and  temperature is consistent each time the test is performed. For mobile  users a 12V/240V dual voltage incubator can be used.

Cooling tower water should be be tested using dipslides on a weekly basis.  The consistency of timing when  microbiological testing is important and the sample should not be  taken if biocide has recently been applied. The clarity of the sample is not indicative of bacteriological activity and the test should be  carried out regardless of sample clarity.

If the treatment programme is effective, the dipslide counts should be consistently low (<10⁴).  If an unusually high result is obtained, the test should be repeated  as soon as possible and confirmed.  Once confirmed appropriate  corrective action should be taken.
