Sulphate reducing bacteria (SRB) is a bacteria that can obtain energy by oxidising organic compounds / molecular hydrogen and reducing sulfate to hydrogen sulfide. In essence, this bacteria 'breathes' sulfate.
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 sulfate 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 tests will check for signs of this bacteria by using a culture gel.
It comes in a pack size of 10 slides / tests per box (minimum order of 10 boxes).
How to use the SRB Test
Step 1 : Check for any growth
Check that the tube is free from any growth, open and stand upright.
Step 2 : Remove capillary tube
Using sterile forceps, take one capillary tube out of the small vial provided.
Step 3 : Dip into sample
Submerge the capillary tube into your test sample.
Step 4 : Push the capillary down into the Agar
Push the capillary down into the gel in the tube and replace the cap.
Step 5 : Label the tube
If required, label the tube with your test sample details.
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.
- Check that the tube is free from any growth, open and stand upright.
- Using forceps, take a capillary tube (provided) and dip into the sample.
- Blot the end of the capillary onto a clean sheet of paper to empty the tube.
- Push the capillary down into the gel in the tube and replace the cap
- Label the tube and incubate at 30-35 degrees c for a minimum of 24 hours.
- Compare the incubated tube to the results chart included.
Severe infections will normally show results within 24 hours, whilst a slight infection may take up to 48 hours to develop.
A comparison chart is included so you can easily compare your results.
Industry sectors include
- Industrial Water
- Cooling tower water
- Boiler feed water
- Process water
- Metal cutting fluids
Hi, I need 200 slides. How many capillary tubes do you get in 1 box?
Hello, Each box contains 10 SRB dipslides, 10 capillary tubes, 10 dipslide stickers and 1 comparison sheet.
I've used your BTM2 slides for awhile now with good results, and the new instructions are greatly improved. I just tried your SRB slides on diesel fuel, and got a growth of about 1/3 the length of the pipette similar to the "Slight" illustration. At what level would the growth make the fuel unusable? When should the use of a diesel fuel biocide be recommended? Thanks in advance for your help.
Hello, Thank you for your feedback. Regarding the SRB. I'm afraid this is not something we would be able to advise on. We would suggest contacting the manufacture of your of the device you are using the fuel in for advice regarding safe fuel levels.
What is the gel made out of?
Hello, The SRB gel is Iron Sulphite Agar.
