Bulb Droppers
Squeeze the bulb to dispense liquids one drop at a time. These droppers are also known as transfer pipettes.
Droppers with a dispenser box stay organized and protected when they’re not in use. The box has a hinged front panel for easy access to droppers.
Fine tip droppers help you dispense very small volumes. They’re often used with fast-flowing liquids, such as water and gasoline.
Wide tip droppers are good for thicker liquids, such as gel, syrup, and thin paste.
Bellows droppers have a large, accordion-shaped bulb that creates strong suction. They’re often used with viscous liquids.
Droppers with graduation marks have molded markings that won’t fade or wash off.
Sterile droppers are individually cleaned and bagged to avoid contaminating your sample.

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.
Plastic pipettes have a filter to protect their pump from aerosol and splash contamination. Pipette filters are especially important when working with acids and corrosive solutions. 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.
