Where To Buy Plastic Droppers
The small plastic droppers shown here are also called pipettes. They are useful for measuring small quantities of essential oils. We currently carry three sizes of pipettes, (see below for details). For blending purposes, our plastic disposable pipettes are actually preferred over the orifice reducers for the control and accuracy they offer. We definitely recommend the use of pipettes for more viscous oils, which do not pass easily through a reducer (ex: Vetiver, Cocao Absolute, Sandalwood). Pipettes are also helpful for thinner oils, such as citrus oils, which often drop out of an orifice reducer too quickly.

The Fine Measuring Stem Pipette is useful for pulling or dropping oils out of and into small containers. Disposable plastic, may be reused for same oil. This pipette is marked in increments of .25 ml, up to 1 ml. Full pipette capacity 4.5 ml, approximately 6 inches in length. The Fine Stem Pipette is perfect for removing essential oils from our sample vials! The Measuring Stem Pipette will be too large in diameter for this purpose.

But, for larger sizes (2oz or larger), pipettes can be very handy. We do not recommend the use of glass droppers with a rubber bulb with pure esssential oils. The essential oils causes the rubber to deteriorate rapidly.
Our plastic droppers are not impervious to the essential oils but usually last for years, especially if you occasionally clean them with alcohol and let them dry out. Helpful hint: attach each dropper to it's bottle with a rubber band - that way you do not mix your essential oils.
Sometimes, all you need is a single drop, so make it easy with Dropper Bottles. Constructed of plastic, these lovely bottles feature slender, glass tube droppers that have tapered ends. Use them with assorted types of essential oils when making soaps, lotions, and more!
These Plastic Droppers are perfect for measuring small amounts of liquid, especially fragrance, when making soaps, lotions, lip balms and more. These disposable droppers should only be used once thus reducing your chances of contaminating products. Holds 3 mlLow density polyethylene plastic droppers will not shatter or become a hazard like a glass dropper. Since these disposable droppers are only used once, the chances of contaminating your products with bacteria or fungus is reduced. These droppers will work well whenever there is a need for quick, safe transfer of liquids. Non-Sterile. Holds 3ml. Markings at 1, 2 and 3 ml

Ten clear pipette plastic droppers with long spouts that can handle larger volumes of oil at one time if needed (up to 3ML). They have very good suction and can release very precise amounts of oil as desired. The clear plastic essential oil pipettes make it very easy to see how much liquid you have in the dropper at any given time. Clean up is a snap. Once you empty the residual oil after use, simply fill the dropper with rubbing alcohol and squirt it back out. Ideally, you can use the same dropper for the same oils or similar oils that will not contaminate your application. Since these oils are anti-fungal, anti-bacterial and antiviral, any oil residue left in the pipette dropper before the next use is acceptable for a reasonable period of time. Made from pliable material and resistant to kinks, creasing and smashing.
*Disclaimer* Do not boil glass droppers! Parts with plastic components will start to melt and soften in boiling water. See below for our tips on cleaning glass droppers.
But, depending on the style of dropper, you may be able to remove the glass pipette from the plastic dropper head. Simply pull and wiggle the pipette a bit to get it free from the cap.
Thanks Matilda for your comment! They should come out quite easily- I find wiggling them first from side to side helps get them free. I should say- not ALL dropper bottles will be like this, I have found some are designed not to separate. It just depends on the supplier! In my experience, the Ordinary droppers should come apart. Use your best judgement and, of course, be careful not to hurt yourself when working with all this fragile glass.
For pipette chemistry, we have what you need! Use a pipette (also spelled pipet) when you need to measure or transfer a volume of liquid or solution a few drops at a time. We sell the following types of pipette for your dropper chemistry: Mohr, serological, Pasteur, and air displacement micropipettes. Mohr: Use for an accurate way to deliver small volumes of liquid. The glass tube has permanent graduations in a descending scale. Serological: Disposable, individually-wrapped and sterile plastic pipettes for precision liquid measurements. Its clear tube is printed with black graduations in both an ascending and descending scale. You'll need to use a pipet filler to insert liquids into this item. Pasteur: Often called droppers or an eye dropper, this is a glass tube tapered to a point with a rubber bulb fitted to the top. Micropipette: Use for small-scale chemistry and biology experiments and general lab work. These need disposable pipet tips. Two-step plunger ensures accurate, precise filling and last drop dispensing from the tip. Also find accessories, like a pump, filler, micropipette tips, Barnes bottle dropper, and amber bottle dropper.
An eye dropper, also called Pasteur pipette or simply dropper, is a device used to transfer small quantities of liquids.[1] They are used in the laboratory and also to dispense small amounts of liquid medicines. A very common use was to dispense eye drops into the eye. The commonly recognized form is a glass tube tapered to a narrow point (a pipette) and fitted with a rubber bulb at the top, although many styles of both plastic and glass droppers exist. The combination of the pipette and rubber bulb has also been referred to as a teat pipette. The Pasteur pipette name is from the French scientist Louis Pasteur, who used a variant of them extensively during his research. In the past, there was no equipment to transfer a chemical solution without exposing it to the external environment. The hygiene and purity of chemical compounds is necessary for the expected result of each experiment. The eye dropper, both glass and plastic types, can be sterilized and plugged with a rubber bulb at the open end of the pipette preventing any contamination from the atmosphere.[2] Generally, they are considered cheap enough to be disposable, however, so long as the glass point is not chipped, the eye dropper may be washed and reused indefinitely.
In laboratory use, droppers should not be used for work involving high accuracy since droppers are not designed to measure specific volume; however, it can be used to add drops of reagents. Each type of dropper is designed to produce a specific drop volume, but this is not highly precise. Before using a dropper, the tip should be carefully examined for cracks. To increase accuracy, the pipette is to be rinsed with the reagent. To use the dropper, the bulb is squeezed to expel air out of the pipette and the tip of the pipette is submerged into the solution vertically. The bulb is slowly released to draw the solution up, making sure that the solution does not overshoot into the bulb or else it may get contaminated. To dispense the reagent, the tip is held against the side of the target container at a 30 to 45 degrees angle.[3]
Plastic Pasteur pipettes, also referred to as transfer pipettes, have their stems and bulbs in the form of a single piece made of soft plastic such as polyethylene. The bulb portion is thinner and therefore "squeezable", while the pipette portion is thick enough to be rigid. They commonly come in 1, 2, 3, and 5 ml which comes with a specific drop size of 10, 20, 25, 35, and 50 µl.[6] The volumes are usually marked on the stem, though the markings are rather crude and are not particularly accurate.[7]
A plastic dropper is relatively inexpensive and disposable, so they are often used to avoid cross-contamination. In a solution containing cells and/or protein, it reduces the loss of cell and/or protein that binds to glass. Some plastic pipettes include a long flexible tube that can be bent for drawing solution from small volume tubes.[8]
Plastic Pasteur pipettes are often used in biology where most media are aqueous and solvent resistance is not important. (Most organic solvents, such as hexane and acetone cannot be used in plastic Pasteur pipettes as the solvent can dissolve the plastic.) The pipettes are also hard to wash and are usually discarded with other biohazard waste after one use.[9]
