OilScreenSurface (Swab)®: An "instant" hydrocarbon screening kit for identifying the presence of oil
and petroleum products on solid surfaces, including vegetation, metals and rocks.
The dimensions of this oil screening kit are:
Height 4.625 inches (118 mm), Diameter 0.75 inches (19 mm)
What Is OilScreenSurface (Swab)®?
OilScreenSurface (Swab)® is a rapid test for hydrocarbons on the face of almost any material. A special foam tipped
swab containing isopropyl alcohol in its handle is contained in a clear plastic
tube. When the handle is bent sharply the isopropyl alcohol is released into the
foam. The foam swab is rubbed over the material whose surface is suspected of
being contaminated with oil or other hydrocarbon. The clear container that the
swab came in is filled to the green line with drinkable water. The swab
is then placed back into the clear tube with the swab end toward the bottom. The
cap is replaced on the tube and the contents shaken. If the solution appears
milky there is oil present on the surface! Conversely, if the solution is clear
there is no oil on the surface.
This test is essentially instantaneous in that if oil is present, the
solution will appear slightly cloudy immediately after it has been shaken.
How Does It Work?
OilScreenSurface (Swab)® uses the difference in solubility in alcohol and
water of the compound to be detected. For the test to work the compound to be
tested for must be very soluble in alcohol and practically insoluble in water.
The test kit is comprised of a clear plastic tube that contains a foam swab with
Isopropanol sealed in the handle. A sharp squeeze of the handle forces the
alcohol into the swab. The surface to be tested is swabbed with both side of the
foam tip. The swab is then placed in the clear tube and room temperature potable
water added. The container is sealed with the included cap, and the contents
shaken. If the solution is milky (an emulsion) then the presence of the compound
tested for is indicated. The more milky the solution the more compound is
present on the surface.
Remember the test is non - specific. Any compound soluble in alcohol but
insoluble in water will produce an emulsion (milky solution).
What Can I Use It For?
OilscreenSurface (Swab)® can be used to determine if split spoon samplers,
augers, hand spades, shovels etc. have been decontaminated properly. It can also
determine if fences, leaves, bark or other foliage, rocks, and or metal has been
contaminated with oil or other hydrocarbons. The use is limited by your
Industries that would benefit from using the OilScreenSurface (Swab)® oil
screening kits include:
Transportation facilities and garages (bus barns, fleet vehicles etc)
forestry and pulp and paper, environmental, aerospace, shipping/marine,
manufacturing facilities, petrochemical, utilities and autoshops and car washes.It aso can be used in some
The most common applications for this test kit include:
Checking solid surfaces for oil and oil sheens from leaking utility
Checking for oil and oil sheens on any solid surfaces, including ship
decks, runways, or on vehicles or vehicular parts.
Checking for oil or hydrocarbons on foliage.
Checking for oil or hydrocarbons on metal or painted surfaces, including
industrial machinery and equipment.
Checking for TCA, TCE or PCE on the surfaces of drill cores
... and we have no doubt that our customers will continue to find a wide
range of other applications in future!
How Do I Use OilscreenSurface (Swab)®?
Remove the cap then remove the swab. Fill the tube to the green line withe
drinkable water. To use the swab bend the handle sharply in the middle until a
pop is heard. Use your fingers to force the alcohol from the clear tube into the
foam swab. Then wipe the area with suspected oil contamination using both sides
of the swab. Place the swab into the tube then replace the cap and shake the
tube. If the water turns milky (an emulsion) there is oil or other hydrocarbon
