Amazon sells a variety of syringes
in sizes up to 100 cc; see the ads to the right.
Dharma Trading Company sells syringes that lack any volume measurements on the side, with a total volume of about 20 cc. They also sell 1 or 1.5 cc disposable pipettes, which are like improved eyedroppers, for the same use.

Problems with discoloration of polyester in industriual dyeing Name: Larry
iDye Poly Fabric Dye
Linda Johansen's book
Fabric Dyer's Dictionary
shows how to mix a small number of Procion dyes to obtain a large number of different solid colors
Message: I am a partner in a laundry chemical co that sells/services linen plants. I have a large linen plant that processes white spun polyester. They require steam injection to acheive ideal wash temperatures. The spun polyester has taken on a light yellow cast. My theory is that the boiler chemical(s) designed to flash off in the boiler header have escaped into the wash liquor. The reaction between the optical brightener in the spun polyester and the boiler chemicals have created a reactive dye; thus the discoloration. I am looking for confirmation on my theory. If this is not your area of expertice, perhaps you can direct me.

Try a local feed store. They carry syringes for use with farm animals. If you're in the city, you may have to drive out to the suburbs to find a feed store.
Be flexible about the exact capacity of your syringes. You might not be able to find 144 cc syringes, but if you can find 60 cc or 100 cc syringes, those ought to do the job. (Note that the unit "cc", for "cubic centimeter" is exactly the same size as the unit "ml", for "milliliter".)

PRO Chemical & Dye sells syringes without tips with capacities of 1 cc, 5cc, 10cc, and 20 cc, as well as 10 cc syringes with needle applicator tips.

My area of expertise is only hand dyeing, and I have no links to help in industrial dyeing.
Your hypothesis that some boiler chemical is the cause of the problem seems sound to me. We know that hypochlorite bleach, for example, will permanently stain polyester a dull yellowish color. So, presumably, will any strong chlorine-based bleaching chemical.
However, there is zero chance that this boiler chemical might somehow be forming a reactive dye; a reactive dye is a very specific and complicated sort of chemical, which is not apt to be formed from random reagents. If it were a reactive dye, it would not react with polyester. (See "About Fiber Reactive Dyes".)
What you have here is a contaminant that, although it is not a dye, is reacting with either the polyester or the optical brightener in an undesirable fashion. What happens if you omit the boiler chemical that you most suspect? Is there a ready alternative?
