Bulb Droppers
Squeeze the bulb to dispense liquids one drop at a time. These droppers are also known as transfer pipettes.
Removable bulb droppers are easy to clean.
Soda-lime glass droppers are easier to see through than plastic droppers, and they’re less likely to stain. They withstand chemicals, so you can sterilize them for repeated use.

Bulb Dispensers
Also known as basters, these dispensers transfer larger amounts of liquid than bulb droppers. Liquids are dispensed in a stream, rather than drop by drop. These dispensers are two pieces, so you can remove the bulb for easy cleaning.
Tempered glass dispensers resist staining better than plastic dispensers. They also withstand high heat.
Clear and semi-clear dispensers let you see the liquid inside and confirm the exact volume, unlike silver dispensers.

Disposable Droppers
Pipettes
Pair these pipettes with a pipette pump to transfer measured streams of liquid. Each pipette has a color-coded band that indicates capacity so you can quickly differentiate one from the next.
Borosilicate and soda-lime glass pipettes withstand cleaning chemicals, so you can sterilize them for repeated use. They provide a clearer view over time than plastic pipettes because samples won't stain them. Soda-lime glass pipettes have extremely tight tolerances to dispense the same amount of liquid each time, keeping your measurements precise. Choose a pipette based on the capacity you need to dispense.
Pipettes with graduation marks let you accurately measure samples of various sizes with a single pipette.

Pipettes with Pump
Transfer measured streams of liquid.
Bulb pipettes require two hands.
Plunger pipettes can be used with one hand. Turn the thumbwheel to draw liquid into the pipette, then press the plunger for quick dispensing.
