Pseudomonas bacteria can be particularly prevalent in closed systems and contributes to slime / biofilm formation. The buildup of bacteria and biofilm in these systems can cause operational issues such as:

  • corrosion
  • scale
  • blockages
  • equipment failure
  • system inefficiency

Our closed circuit water system dipslides can be used to test both heated or chilled closed loop systems. These dipslides test for total bacteria count on one side and pseudomonas count on the other side. This gives you a broader view of the levels and types of bacteria that may be in your system.

Flexible paddle

Flexible Paddle

Each dipslide features a virtually unbreakable and flexible paddle allowing for even, full surface testing.

Easy run off design

Easy Run Off Design

Due to the design of the dipslide, fluids will drain off quickly during testing.

Recessed Handle

Recessed Handle

Each slide has a handle built into the lid that is recessed to help keep your fingers dry during testing.

Side Indicator

Side Indicator

One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.

Dual sided paddle

Dual Sided

Each CCWS dipslide is dual sided to allow multiple contamination testing with one test.

Thick reliable Agar

Thick Reliable Agar

Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.

Nutrient Agar - A general purpose medium used to test a wide variety of applications. It offers a total count & promotes growth of non fastidious organisms. This allows for an evaluation of the 'general health' of your sample.

Pseudomonas CFC Agar - This agar assists in the detection of all pseudomonas species. 

How to use the CCWS dipslides

In Liquids

Simply remove the dipslide and immerse in the sample for approx 10 seconds. Remove dipslide and allow to drain for a few seconds, then replace the slide back into the tube and incubate for a minimum of 24 hours (up to a maximum of 48 hours).

A comparison chart is included so you can easily compare your results.

Remove Nutrient / Pseudomonas slide from tube

Step 1 : Remove slide

Carefully remove the sterile Closed Circuit System dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).

Liquid Testing

Step 2 : Liquid testing

For liquid testing, immerse the Closed Circuit System dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.

Incubate the dipslide

Step 3 : Incubate Slide

Label the tube with the included stickers then place the slide into an incubator and allow to incubate.

compare dipslide results

Step 4 : Compare results

Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.
