Overview

FuelClear™ M68 Test Kits are a simple, accurate and cost- effective method for continuously monitoring the presence of bacteria & fungi (The Diesel Bug) in hydrocarbon fuels. Unlike some tests, M68 detects both bacterial and fungal contamination and has been used by some of the world's largest shipping companies for detection of microbes in fuel storage. 

The dipslides can be dipped into a fuel sample, incubated in a supplied tube for 48 hours and then measured against a chart provided with the pack.

Note: FuelClear™ M68 Test Kits are not used for aviation and MicrobMonitor 2 should be used instead.

Product Conforms to EC 1907/2006 (REACH). Not to be used for Aviation Applications.

Application

The packs of M68 either contain 2 or 10 dipslides: 1 test can be performed prior to treatment with FuelClear™ M68 Biocide and 1 test 24 hours after treatment. Alternatively, use as an ongoing cost-effective test method. The dipslides can be used to detect bacteria (the yellow side of the test kit) or fungi (the pink side) in either water bottoms (i.e. the layer of water at the base of the fuel tank) or the fuel itself. Each slide is covered in the suspect fuel for 5-10 seconds.

Following 48 hours incubation (locate the dipslides at room temperature or somewhere slightly warmer such as an engine room), review the dipslides for microbial colonies. Each colony represents a concentrated area upon which microbes have developed. If there is any concern over the veracity of the result, repeat the test with another dipslide or contact Fuelcare. If the test reveals medium to extreme growth treat urgently with FuelClear™ M68 fuel biocide.

1. Remove cap without touching the gel, withdraw the dipslide.

2. Immerse the dipslide in your fuel for 10 seconds ensuring adequate coverage on both sides.

3. Allow excel fluid to drain for a few seconds.

4. Replace the dipslide into the clear plastic tube and label as required.

5. Leave the product to incubate in a warm environment (30°C) for 48 hours.

6. Bacterial contamination is shown on the white side of the slide, yeasts & moulds on the pink side. Compare incubated slides after 48 hours against the comparison chart.

Fuels: All middle distillate fuels including Diesel, Gas Oil, Petrol, Heating Oil, Biodiesel, Fuel Emulsions.

Industries: Marine, Rail, Agriculture, Automotive, Home Heating & Power Generation sectors.
