9. Detector Ticket
A detector ticket (6, fig. 2) is a thin (approx 3/64 inch) plastic holder, approximately 2 inches long by 1 inch wide,
rounded at one end and square at the other. A fiberglass disk is mounted in a circular hole in the square end; a second
fiberglass disk is mounted in a circular depression in the rounded end. Forty detector tickets are contained in a strip (belt)
of individually sealed plastic envelopes.
10. Detector Tube and Sampling Tube
a. There are four types of glass detector tubes in the ABC-M18A2 kit (blue-band, red-band, green-band, and
yellow-band). Each glass tube is 3 inches long and sealed at both ends. A small quantity of chemical-impregnated silica
gel is held in the middle of the tube by fabric plugs and a short piece of wire. The impregnate is a different chemical
reagent for each of the four types of detector tubes. The tube is lightly scored about 5/8 of an inch from each end to
permit the ends to be broken off easily. Each tube is marked at one end with two colored bands, one on each side of the
score mark. Twenty-five detector tubes of a single type are packaged in a fiberboard clip (3, fig. 2). A discard date is
marked on the outside of the carrier. The tubes should not be used after this discard date is reached.
b. Sampling Tube. A sampling tube is identical with a detector tube except that the silica gel it contains is not
impregnated with a chemical reagent. Sampling tubes are marked with two white bands in the same manner as detector
tubes. They are packaged 25 in a fiberboard clip.
11. Instruction Cards
Six plastic cards (12 pages) contain instructions for use of the kit (para 21 through 30, test Procedures). Instruction cards
(2, fig. 2) are arranged in order and are fastened together by one end of a cord, the other end of which is attached to the
12. Plastic Squeeze Bottles
Three squeeze bottles (7, fig. 2) are made of translucent plastic. They are approximately 2-5 /8 inches high and are fitted
with screwcaps, which cover and protect removable dropper tips. Tips can be removed from the tops of the bottles with
finger pressure. Each bottle is equipped with a colored plastic cap which matches a colored band on the bottle. The blue-
marked bottle contains a solid reagent which must be dissolved in water before it is used. The white-marked bottle
contains buffered water solution. The green-marked bottle is empty; it is used to contain a reagent solution which must be
prepared fresh each day that the kit is used (para 17).
Solid reagents used to prepare the solution to fill the green-marked bottle are held in a plastic container (12, fig. 2).
a. Fourteen tablets are contained in a small glass vial (10). The stopper and the top third of the vial are green.
b. Fourteen straws containing powder reagent (11) are made of clear plastic; they are about 5/32 inch in diameter
and 1-7/8 inches long.
The substrate dispenser (13, fig. 2) is a plastic coated glass bottle (1/2 ounce) capped with a red- marked plastic nozzle
(1). The nozzle is covered with a removable plastic protective cap (2). The dispenser is filled with substrate solution
under pressure. Carefully depressing the top of the dispenser releases substrate solution drop-by- drop from the nozzle.
