• Designed for safety from electrostatic hazards during filtration
• To collect solid contaminants from a fuel sample for gravimetric determination
• Hands-free method for transferring sample to the filter funnel
• Support stand in accordance with ASTM Method D5452
• Stable support is adjustable, aluminum construction
• Accessory items for D5452 procedure are available
• This apparatus is well suited to perform three tests:
  • Gravimetric determination of particulate content, per D5452
  • Membrane color per D5452
  • Filter time test per US Air Force Technical Manual T.O. 42B-1-1

As described in ASTM Method D5452, the support stand is designed to hold the container that was used to collect the jet fuel sample in the field. There is no need to transfer the sample from the collection container to another container, thereby eliminating possible contamination from the second container.

Using a flexible dispensing tube assembly that fits the thread of the port in the top of the sample container, the operator closes the tube with the clip to prevent the release of fuel when the container is being turned upside-down to place it on the support stand upper shelf. The tube is then positioned in the filter tunnel before releasing it. This allows fuel to fill the funnel but it will not overflow because air must return to the container through the same tube. The filter funnel remains full in the same way that a bird feeder operates because the lower end of the tube is below the fuel surface in the funnel.

Vacuum in the collection flask draws fuel through the membrane filter desk that is positioned at the base of the filter funnel. Hands-free operation is assured. The operator is no longer required to hold the container as fuel is poured into the filter funnel. The potential for spillage is virtually eliminated.
