Quick answer: A glass dropper bottle is used to store and dispense small, controlled drops of a liquid reagent, indicator or sample, commonly used alongside titrations and staining procedures.
The bottle is fitted with a dropper cap, typically a rubber or plastic teat over a glass or plastic pipette tube, which draws liquid up when squeezed and released. This allows a precise number of drops to be added to a reaction or preparation without pouring, which is especially useful for indicators in titrations, staining reagents in microscopy work, or any procedure where only a few drops of reagent are needed at a time.
Glass dropper bottles are a familiar sight on the laboratory bench and reagent shelf, valued for being easy to see into, chemically inert to most common laboratory reagents, and simple to refill and reuse.

Frequently Asked Questions
What is a glass dropper bottle used for?
It is used to store and dispense small, controlled drops of a liquid reagent, indicator or sample, such as titration indicators or staining solutions.
How does the dropper mechanism work?
A rubber or plastic teat fitted over a glass or plastic pipette draws liquid up when squeezed and released, allowing drops to be dispensed one at a time with good control.
Is the dropper bottle suitable for light-sensitive reagents?
Clear glass dropper bottles allow contents to be seen easily, but light-sensitive reagents are better stored in an amber glass bottle; confirm which glass type this bottle uses at enquiry.
Can the dropper bottle be reused with different reagents?
The bottle can be reused after thorough washing and rinsing, but avoid switching between chemically incompatible reagents without proper cleaning to prevent cross-contamination.
What capacity does this dropper bottle come in?
Dropper bottles are supplied in a range of standard laboratory sizes. Confirm the exact capacity you need when placing your enquiry.
Does LabEquip supply dropper bottles for bulk or institutional orders?
