Limitation of 3M Liability
3M WILL NOT BE LIABLE FOR ANY LOSS OR DAMAGES, WHETHER DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT LIMITED TO LOST PROFITS. In no event shall 3M’s liability under
any legal theory exceed the purchase price of the product alleged to be defective.
Storage and Disposal
For maximum shelf life, store between 2°C - 8°C (36°F - 47°F). Alternatively, swabs are stable for 28 days when stored
at room temperature; for this storage option do not exceed 21°C (70°F). Store in pouch until time of use. Expiry date and
lot number are noted on each pouch.
Instructions for Use
Before the 3M Clean-Trace Surface ATP test device is activated, it is important to ensure your 3M Clean-Trace NG
Luminometer is switched on and initialized. Refer to the manual provided with the instrument for full details.
1. Place the 3M™ Clean-Trace™ Surface ATP tests at room temperature for at least 10 minutes before use. Immediately
before use, remove the test device from the foil pouch. Grip the sample stick handle and remove the swab from the
test device.
2. Swab the test area. Where practical, swab an area approximately 10 cm by 10 cm and swab the area in one direction
and then swab the area in the opposite direction [gure 1]. Apply pressure on the swab and rotate the swab as the
sample is collected to ensure repeatable and eective sampling [gure 2].
3. Re-insert the sample stick into the 3M Clean-Trace Surface ATP test device with the handle inserted to the original
position of the unused test device. At this point you can either activate and measure immediately, or, if it is more
convenient, the 3M Clean-Trace Surface ATP tests may be labeled, stored in the pouch, and left un-activated for up
to four hours before activation and measurement.
4. To process the sample, push down rmly on the top of the 3M Clean-Trace Surface ATP sample stick handle
[gure 3]. The handle will slide into the test device tube and the top of the handle should be level with the top of the
test device tube when fully depressed. Grip the top of the test device and shake rapidly side-to-side for at least ve
seconds to mix the sample and reagent [gure 4].
5. Immediately open the sample chamber of the 3M Clean-Trace NG Luminometer and insert the 3M Clean-Trace
Surface ATP test device. Close the chamber cap and press the measure button. The light emitted by the 3M
Clean-Trace Surface ATP test will be measured and the result (in RLU) will appear on the display [gure 5].
How to best utilize 3M™Clean-Trace™Surface ATP
Do Do Not
Hold the 3M Clean-Trace Surface ATP test device in the
VERTICAL position on activation and shake rapidly from
SIDE TO SIDE for at least 5 seconds and read immediately
in the 3M Clean-Trace NG Luminometer.
Activate when not in the vertical position, do not shake up
and down, do not shake like a thermometer.
Replace the swab in the tube but do NOT activate the
3M Clean-Trace Surface ATP test device if test devices
are to be taken back to another location for testing. Only
activate when you are about to measure the test device.
Activate all 3M Clean-Trace Surface ATP test devices then
take them to another location for testing or activate and
leave on a surface to test one at a time.
Activate and measure 3M Clean-Trace Surface ATP tests
ONE AT A TIME when a number of samples are to be
measured.
Activate all 3M Clean-Trace Surface ATP test devices and
then test one at a time.
Place the 3M Clean-Trace NG Luminometer in the vertical
position when a measurement is made. Hold the 3M Clean-Trace NG Luminometer horizontally or
lay down on the bench to read a 3M Clean-Trace Surface
ATP test device.
Always remove the last 3M Clean-Trace Surface ATP
test device from the 3M Clean-Trace NG Luminometer
chamber when the measurement is completed.
Leave a 3M Clean-Trace Surface ATP test device in the
chamber when the measurement is completed.
Interpretation
• The higher the RLU number, the more contaminated the sample.
• It is usual to set predetermined pass/fail levels so that users of the system know what action is required once the
result is known.
• NOTE: Even a perfectly clean sample will not give a zero result as the instrument and 3M Clean-Trace Surface ATP
test device has a “background” RLU level.
