Sulfate / sulphate reducing bacteria can cause corrosion and fluids may become rancid if SRB levels are high. SRB is well known for its microbial corrosion of pipelines but can also be a problem in metalworking facilities.

Our SRB anaerobic culture gel test tubes detect the presence of sulfate reducing bacteria efficiently and can be used to test metal working fluids.

There are 10 tubes in each box and each contains an amount of culture gel for testing.

How to use our SRB tests to analyse metalworking fluids

When your SRB tests arrive, you will notice that there will be 2 types of tubes (10 x culture tubes and a thinner container that contains 10 x capillary tubes). The capillary tubes are used to collect samples.

To test your metalworking fluid:

  1. Make sure that the culture gel test tube is upright and has no indication of any growth inside.
  2. Using forceps or similar instrumentation, remove a capillary tube from the container provided and use it to collect a fluid sample.
  3. Using a clean piece of paper, blot and empty the capillary carefully.
  4. Place the capillary in the culture gel tube and replace the cap.
  5. Place a label on to the tube so it is easy to identify.
  6. Incubate for a minimum of 24 hours at 30 - 35 degrees celcius.
  7. Compare the results of the slide after incubation with the chart provided.

The speed and amount of black colouration of the culture will indicate the level of SRB in the sample. Severe infections will show within 24 hours with slight infections taking longer to develop.

Check the SRB for any growth, open and stand upright.

Step 1 : Check for any growth

Check that the tube is free from any growth, open and stand upright.

Surface testing

Step 2 : Remove capillary tube

Using sterile forceps, take one capillary tube out of the small vial provided.

Liquid Testing

Step 3 : Dip into sample

Submerge the capillary tube into your test sample.

Swab Testing

Step 4 : Push the capillary down into the Agar

Push the capillary down into the gel in the tube and replace the cap.

Incubate the dipslide

Step 5 : Label the tube

If required, label the tube with your test sample details.

compare dipslide results

Step 6 : Incubate / compare results

Incubate at 30-35 degrees C for a minimum of 24 hours. Once incubated, compare the results with the chart provided.

You will need an incubator to interpret your results. We offer a variety of sizes in our incubator section.
