Storage
Store 3M Quick Swab at temperatures ≤8°C (≤46°F). Exposing the 3M Quick Swab to temperatures >25°C (>77°F) can
affect the performance of the product. Lot numbers and expiration dates are noted on each box or case of 3M Quick
Swabs as well as on each swab.
Disposal
As with all environmental surface sampling swabs, once used, the 3M Quick Swab may be a potential biohazard. Follow
current industry standards for disposal.
Instructions for Use
Follow all instructions carefully. Failure to do so may lead to inaccurate results.
Prior to use, visually inspect each 3M Quick Swab. Use only if the letheen broth is in the bulb end of the swab and the color
of the broth is clear amber, not turbid or cloudy.

1 mL Plating Instructions - Wet Swabbing Method -
1
Label each 3M Quick Swab.
2
Bend the red snap valve at a 45°
angle until you hear the valve
break. This allows the letheen
broth to flow into the tube end and
wet the swab bulb.
3
Squeeze the bulb of the swab to
transfer all of the letheen broth
to the tube end of the swab.
4
Twist and pull apart the bulb end
of the swab from the tube end of
the swab that contains the letheen
broth.
5
Hold the swab handle to make a
30° angle with the surface. Rub
the swab slowly and thoroughly
over the desired surface area.
Rub the swab three times over
this surface, reversing direction
between alternating strokes.
6
After sampling is complete,
securely insert the swab back
into the swab tube and transport
to the lab for inoculation. Plate
the letheen broth swab solution
as soon as possible.
7
In the lab, vigorously shake or
vortex the 3M Quick Swab for 10
seconds, to release bacteria from
the swab tip.
8
Wring out the contents of the
swab tip by pressing and twisting
the swab against the wall of the
tube.
9
Carefully pour the entire
contents of the tube onto a
3M Petrifilm Plate. Follow
current industry standards for
disposal.
