Medicine Dropper Assembly Components explained
Dropper Bulb Material
Straight Tip Pipette
- General Purpose Dropper Pipette found in 90% of the dropper market (Variation of Bent tip).
- Intended for low viscosity liquids
- Creates a smaller drop due less surface area (surface tension)
Blunt Tip Pipette
- Special purpose Dropper Pipette Found in 10% of the dropper market.
- Intended for high viscosity liquids and select gels.
- Creates a lager drop due to orifice size.
- Transferring liquid
- May be used for sensitive soft-area administration
The blunt tip pipette is often used for transferring larger volumes of liquids. The wider opening at the end allows for faster and more efficient pipetting of larger quantities. This makes it suitable for tasks that involve transferring bulk solutions or working with samples that require a higher volume.
Blunt tip pipettes can be used in applications where the liquid being dispensed is less likely to damage delicate tissues or structures when dispensing liquids. Example, when administering medication to the eyes or ears, a blunt tip Dropper can be less likely to cause discomfort or injury to the patient.
Glass Pipette vs Plastic Pipette
Glass pipettes are generally less durable as the material is brittle yet most resistant to chemicals and high temperatures compared to plastic LDPE pipettes.
Glass pipettes are easier to clean and sanitize by autoclave and can be reused (Type I borocylicate), making them more environmentally friendly. Glass pipettes are considered more efficient to manufacture by our methods and will come in at a lower cost by volume. All Glass Pipettes are formed to fit your needs by length, tip style, and calibrations & Decorations.
Plastic LDPE pipettes are lightweight and can be more affordable than glass pipettes in lower quantities. They are considered one use and are disposable, which eliminates the need for cleaning and reduces the risk of cross contamination between samples. Plastic LDPE pipettes are also more flexible than glass pipettes, making them easier to use in hard-to-reach areas.
We manufacture a wide variety of Plastic pipette droppers to fit most general needs.

History of the Medicine Dropper Assembly
The invention of the Medicine Dropper is not attributed to a single individual. However, the use of small dropper-like instruments for dispensing liquids can be traced back to ancient times. In ancient Egypt, for example, hollow bird bones were used to transfer fluids, and the Romans used glass tubes to transfer liquids in medicine.
The modern eye dropper as we know it today is thought to have been developed in the late 19th century. In 1872, the American inventor Charles Barnes patented a “new and useful improvement in eye-droppers” that featured a rubber bulb for squeezing and a glass dropper tube. Other inventors, including Joseph H. Batten and William E. O’Brien, also filed patents for similar devices around the same time.
The use of medicine droppers for administering medications became more widespread in the early 20th century, as advances in medicine and manufacturing made it possible to produce and distribute liquid medicines on a larger scale. Today, medicine droppers are an essential tool in ophthalmology, optometry, and many other fields where precise, controlled dispensing of liquids is necessary.
FAQs
Frequently asked Medicine Dropper Assembly questions.
What is a Medicine Dropper Assembly?
A dropper is commonly referred to as; Medicine Dropper, Liquid Droppers, Med Dropper, eye dropper, dropper assembly
or dropper assemblies, pipettes and pasture pipettes. These devices are
used as a liquid despising device by the means of creating a vacuum and
drawing the liquid up into the tube (pipette) until the user choose to
dispense it by then squeezing the bulb which releases the vacuum.
Can you make a custom Medicine Dropper Assembly not shown above?
Yes – All of our dropper assemblies are made to order. RTN holds the majority of popular components in stock and schedule assembly after an order is received.
What parts make up a Medicine Dropper Assembly?
Eye dropper assemblies at RTN are made up of three components;
pipette, closure and, bulb. We offer many different variations of each
component to meet your requirements. We offer Glass in Soda lime Type
III (T3), Glass Borosilicate Type I (T1) and, Low Density Polyethylene
(LDPE) in both plain and custom calibrations (decorations). Our closures
