Black PP plastic 22-400 ribbed skirt dropper assembly

The M2472BK is a black PP plastic 22-400 ribbed skirt dropper assembly with rubber bulb and 102 mm straight tip glass pipette. Dropper assemblies are composed of a number of parts: the cap, the bulb and the pipette (tube). Dropper assemblies are used with liquids that require precision and intricacy when using the product. The dropper bulb output is 0.8 cc. Polypropylene (PP) is marked with the resin identification code of 5. PP is less flexible than LDPE, somewhat stiffer than other plastics, reasonably economical, and can be translucent, opaque, or of any color. PP has very good resistance to fatigue, and has an extremely high melting point (320 degrees Fahrenheit or 160 degrees Celsius). This closure fits a container with a neck finish. The first number refers to the diameter of the container’s opening (in mm). The second number refers to the thread/style/depth of the closure’s skirt.
