Our (76 mm) 1 oz Graduated Glass Pipettes are industrial grade glass with black markings on the .25ml, .50ml, .75ml, and 1mL fill points. These 1 oz graduated glass pipettes are meant to be paired with our plastic dropper assemblies. You can pair them with either child resistant, non-child resistant, or tamper evident dropper caps. Each glass dropper is meant for a particular size fo a dropper bottle. Therefore, this glass pipette, in particular, is meant for the appropriate length of a (30ml) 1 oz dropper bottle. It fits the length of either Boston or Euro round glass bottles depending on the cap style.
Glass makes a great choice for packaging due to its high clarity and chemical-resistance levels. Glassworks extremely well against resistance to heat and cold. Therefore, glass makes a great tool when packaging products with Cosmetics, Essential Oil, and other liquids.
