SRB Test Kit

Sulphate reducing bacteria (SRB) is a bacteria that can obtain energy by oxidising organic compounds / molecular hydrogen and reducing sulphate (sulfate) to hydrogen sulfide. In essence, this bacteria 'breathes' sulphate.

Sulphate reducing bacteria are anaerobic organisms that cause corrosion and spoilage in multiple industries. The bacteria can cause particular damage to oil pipelines and metal parts.


Survives in oxygen depleted / oxygen free environments
Corrodes at a very fast rate
Reduces sulphates and creates hydrogen sulfide
Resultant hydrogen sulfide gives off a foul 'rotten egg' odour
Other signs of its presence in water is a change in colour (to black)
Major cause of microbial influenced corrosion

Our SRB test kit will check for signs of this bacteria by using a culture gel. The gel will turn black if sulphites are present in the test sample. Sulphites are produced when sulphates are reduced by bacteria. The amount of colour change can be compared with the included chart to help determine the level of contamination.

It comes in a pack size of 10 slides / tests per box. 

  • Add 2ml of the test sample to the tube. To aid the user, 2ml of test sample can be determined by adding the sample up to the moulded line in the tube.
  • Incubate the SRB test / dipslide at 30 degrees C for up to 5 days. Check the test daily for the first three days.
  • If there is no colour change after 5 days, this indicates a negative result.

How to use SRB Test Kit

Remove SRB test kit cap.

Remove SRB test cap

Remove one SRB test from the SRB test kit and unscrew the cap (anticlockwise) to remove it.

Add 2ml of sample fluid to the SRB test.

Add 2ml of sample fluid

Add 2ml of sample fluid to the SRB test. If you do not have a measuring syringe, fill the tube up to the embedded fill line on the tube (which equals 2ml).

Replace the cap

Replace the cap

Replace the cap on the SRB test and incubate accordingly.

Check the SRB test

Compare the SRB colouration with the chart provided.

Due to the size of the tubes, for incubation with these SRB tests, we recommend using MX8, MX10, MX25 or MX45. The tubes are too narrow to guarantee accurate incubation using the MX2. The MX8 incubator is sealed with a lid which will trap the heat so the size of the chambers should not affect incubation.
