ECHA Microbiology- SIG Rapide WB- Microbial Presence Test Kits
ECHA Microbiology, SIG Rapide WB, Microbial Presence Test Kits
FOR RESULTS IN 1 HOUR @ 35°c APPROXIMATELY
The Sig Rapid WB™ test is design to detect the levels of microbes typically found in water associated with fuel and is not designed to test fuel directly. To test a fuel phase sample directly please use the MicrobMonitor2 test.
Microbial proliferation cannot occur in fuel without the presence of some free water. The microbes first develop in this water and later spread into the fuel. Few fuel systems with water associated with them are completely free of micro-organisms but the level of sensitivity of the test is such that normal and acceptable levels of microbial contamination are not detected. A positive result in the test indicates an abnormal level of microbial contamination in the water tested and by implication strongly suggests unacceptable microbial proliferation in some of the fuel/water system sampled. Conversely a negative result in the test strongly suggests that the fuel/water system sampled will be unlikely to be operationally affected by microbial spoilage. Microbes in large volumes of fuel tend to settle towards the bottom water and are detectable by the Sig Rapid WB™ test. Upper fuel may then not be heavily infected, however, movements of fuel will probably disturb and redistribute bottom contamination.
The Sig Rapid WB™ test is designed to detect microbial contamination in water phase when active proliferation has begun. It is not designed to detect the normal background levels of microbes present in water associated with fuel. Therefore it will not give a strong positive result if microbes are not actively multiplying and growing on the fuel which the water is associated with.
The shelf Life of the test is 6 to 12 months dependant on storage conditions. 12 months when stored frozen, 6 months when stored in a cool dark room or refrigerated.
The Sig Rapid WB™ test can be used to test;
Product Features:
TRUSTED

Fuelstat Resinae Plus and Diesel Plus-Microbial Load Analysis Kits for Diesel and Aviation Fuels
- Fuelstat Resinae Plus and Diesel Plus, Microbial Load Analysis Kits for Diesel and Aviation Fuels
- FOR RESULTS IMMEDIATELY
There are a number of different types of micro-organisms that can grow in certain types of fuel. The biggest problem is presented by a lamentous fungus called Hormoconis Resinae (H Res). Previously called Cladosporium Resinae, and more commonly referred to as “Jet Fuel Fungus” or "Diesel Bug".
H Res is a fungus that thrives in fuel. It requires only a minimal amount of water content in the fuel to grow and will cause filter blockages, contents gauging errors due to the fouling of sensors, and corrosion damage to tanks, pipework, pumps and meters if left unchecked. Bacteria and other types of fungi, particularly some yeasts can also cause problems in fuel tanks, usually acting as a consortium.
The objective of the test is to provide rapid screening of fuel samples (water in fuel or fuel only), giving a quick and accurate assessment of H Res, bacteria & other fungi including yeasts in the fuel tank. This test is unlike current growth-based tests, which require a minimum of 72 hours to provide any results. The test measures the amount of active growth in the sample and provides actions and alert levels.
The FUELSTAT® Resinae PLUS and FUELSTAT® Diesel PLUS tests measure the amount of different types of contamination: H Res, bacteria and fungi actively growing in the sample and reports that as the weight of material in the sample. This is a newer, more accurate measurement system than the old Colony Forming Unit (CFU) count. - The test provides results based on a traffic light scenario:
- Negligible (green) – negligible contamination
- Low Positive (amber) – moderate contamination
- High Positive (red) – heavy contamination
- SIX DEVICES ARE INCLUDED IN EACH TEST (and 8 tests are included in each kit):
- Right side of paddle (LOW) 3 devices with cut off levels for H Res, bacteria and fungi at a level derived from IATA Guidance Material where the microbes have established themselves as a consortium and a fuel treatment is required.
- Left side of paddle (HIGH) 3 devices with cut off levels for H Res, bacteria and fungi at a level derived from IATA Guidance Material where the microbes are growing so rapidly, or have been growing for a long time that they may be causing damage to the structure of the tank or are likely to cause filter blockage and component failure and a tank clean and fuel treatment are required.
- TEST CONTENTS:
Each heat sealed foil pouch contains a Paddle with desiccant sachet and pipette in one section and Sample Extraction Bottle with flat cap, dropper cap and instructions for use in the other section. - Paddle: Plastic base with 6 lateral flow devices affixed
- Preparation Bottles: 175ml plastic bottle with flat cap and “dropper” cap containing 3.0ml of Sample Extraction Liquid
- Disposable, single use, plastic pipette
- Instruction leaflet
- FUEL HUSBANDRY
Rather than treat contamination when significant operational or fuel quality problems arise it is better to prevent microbial growth occurring, much can be done to ameliorate problems associated with microbial contamination in fuels, these include: - Allowing fuel deliveries to settle in the tank for 24 hours before putting the tank back into service.
- Drain any accumulated water from the bottom of the tank weekly.
- Routinely test bottom samples for microbial contamination.
- Treat fuel if required, according to test results.
- STORAGE AND STABILITY
- No special transport precautions
- Store below 30°C, but no special storage precautions otherwise
- Use between 10°c and 30°C
- Do not use after the stated expiry date, expiry date is 24 months from the date of manufacture, we aim to deliver with at least 12 months of the lifespan still intact. If longer is required please advise.
- Long term freezing is not recommended
- Why Use FUELSTAT®?
- FUELSTAT® complies with ASTM D8070-16. This enables users to rapidly test on-site and provide closer adherence to ASTM D6469
- ASTM D6469 – 14, Para 8.5, Standard Guide for Microbial Contamination in Fuels and Fuel Systems section states: Samples for Microbiological testing should be kept on ice for transport to the laboratory. Tests should be performed within 4 h and no later than 24 h after sampling. Samples stored at higher temperatures, or for longer times, can show the presence of microbial contamination that does not represent actual fuel system conditions.
- British Standards Institute BS 5410-3:2016, Testing of Fuel within Standby Generators Section 18.10 Fuel Filtration – Filters states: 1) There should be a fuel polishing system to help maintain the fuel quality, if there is no polishing system the fuel should be tested every three months. 2) Fuels for emergency generators should be tested every six months for quality and suitability.
- Since the introduction of Biodiesel (FAME) the quality and life expectancy of diesel fuels has been adversely affected. FAME is hydroscopic so a portion of the water in the fuel goes into suspension. This water can lead to injector pump damage and facilitate the growth of bacteria which blocks conventional filters.
- FUELSTAT® does not have any special handling, transportation, storage or disposal requirements.
- FUELSTAT® does not require any special skills or capital equipment
