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.

The original purpose of the pipet was to transfer small quantities of medicine or fluid without contamination. The bulb at the end helps control the fluid, allowing much safer and better manipulation than with a teaspoon or similar device.

The constriction toward the tip of the Pasteur pipettes may be plugged with a bit of tissue paper or cotton wool to filter off solids from small amounts of liquids. The bulb can be attached and squeezed to help viscous solutions filter more rapidly. [10] Different medicine droppers have different markings, so it's important to use the correct dropper that corresponds to your medication. The glass tubes were then broken in half to make two Pasteur pipets. Glass medicine droppers were the only option for chemists and pharmacists until the invention of plastic models in the 1940s. Since then, Pasteur pipets have been in used at home, for inpatient and outpatient care as well as laboratory tests. What are the Common Uses for Medicine Droppers?

The two types of glass that are usually found in the laboratory and in the Pasteur pipette are Borosilicate glass and Soda lime glass. Borosilicate glass is a widely used glass for laboratory apparatus, as it can withstand chemicals and temperatures used in most laboratories. Borosilicate glass is also more economical since the glass can be fabricated easily compared to other types. Soda lime glass, although not as chemically resistant as Borosilicate glass, are suitable as a material for inexpensive apparatus such as the Pasteur pipette. [5] Plastic Pasteur pipette [ edit ] The first Pasteur pipets were made of thin glass, blown and stretched while they were still hot to make their signature shape. Suggest that your child holds his nose while taking the medicine, so lessening the effect of the taste. Louis Pasteur is known around the world as the man who discovered that heating food and drink helped keep these products safe from contamination. But he invented the process of pasteurization because of an earlier theory he came up with, Germ Theory. Pasteur correctly deduced that microbes were responsible for the spread of disease. A: Ideally, yes. It should be kept clean and sterilized to prevent the spread of bacteria and other harmful microorganisms.

Remember: never use a kitchen spoon to measure out medicine. This is because kitchen spoons come in lots of different sizes. If you see instructions in teaspoons (tsp) or tablespoons (Tbsp), and you are confused, talk to your doctor or pharmacist. Medicine cups give you information in the language you prefer. Having an interpreter help give you instructions, and having information written down in the language you prefer, means that you will be less likely to make an error. Medicine droppers are common medical devices that are used extensively in laboratory settings as well as in households for dispensing medicine. These devices look like thin tubes made of plastic or glass, tapering off to a narrow end. They usually have a rubber or plastic bulb at the end for facilitating liquid intake. Air pressure and vacuum help draw fluid up the pipe, making them ideal for transferring blood samples or dispensing cat medicine. higher doses of infant medicine to a child, thinking that it is not as strong.
