Tektrak microbiological dipslides
Industrial microbiological dipslides for oil/water testing of coolant sumps/systems, oil systems, oil and water storage tanks
Bacterial testing of systems should take place on a weekly basis incubating dipslides for required period and required temperature as specified below:
PRICE REDUCTION FROM £18 TO ONLY £8 PER BOX
| Code | Description | |
| F201A | Combination microbiological dipslide for aerobic/coliform (SCT) 35°C for 24-48hrs |

(Initial readings after 24 hours will show accurate higher levels of contamination - slight contamination may only show after 24 hours of incubation)
All have a shelf life of 9 months.
Each box of 10 contains instructions, labels and expiry date.
Anaerobic Bacteria (Culture Tube Test)
These bacteria exist when the oil is stagnant. They reduce chemicals in the oil emulsion to give hydrogen sulphide which is the noxious 'Rotten Egg' smell given off when the oil is disturbed. They also give off acids which reduce the alkalinity of the emulsion and in certain cases promote corrosion.
Coliform Bacteria
These are bile tolerant bacteria, which pass through the body of animals or man and emerge in the faeces. Whilst they are not necessarily pathogenic there are pathogenic bacteria usually associated with them. These are usually shigella and salmonella. It is easier to detect the Coliform bacteria, which are present in greater numbers. If a significant number - say 10/5 colonies/ml - are regularly found, medical advice should be sought. The majority of bacteria found in oils are non-pathogenic, but there are occasions when "opportunist' pathogenic bacteria may be present.
There are at least three ways in which these can enter the body: -
- Ingestion of spray. Spray removal equipment should be used.
- Entry through cuts in the skin. These should be protected.
- Entry through defatted skin pores. Paraffin or similar solvents should not be used to wash hands. Barrier creams and proper non-abrasive soaps should be provided.
The possibilities for unrestricted growth of bacteria should be minimised and this can be summed up:
- Good housekeeping to keep oils clean i.e. pipes, storage and stop water leakages into oil systems
- Clean the tanks, pipes, with a steriliser/cleaner before introduction of fresh oil
- Use an oil containing a biocide effective against bacteria, yeasts and fungus or treat symptomatically using Tektrak Aquabac 80.
- Identify by testing first stages of bacterial contamination so that the problem may be treated.
Bacterial Contamination in Water Systems
The Coliform slide may be used to check all water systems including cooling water, ballast and boilers. The count is not high enough to give a low enough count for drinking water systems but will identify a potential risk of system fouling or risk of Legionella disease i.e. see dipslide user guide. A full RBS/SCT/SRB check is recommended.
