Bulb Droppers
Squeeze the bulb to dispense liquids one drop at a time. These droppers are also known as transfer pipettes.
Fine tip droppers help you dispense very small volumes. They’re often used with fast-flowing liquids, such as water and gasoline.
Removable bulb droppers are easy to clean.
Droppers with graduation marks have molded markings that won’t fade or wash off.
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.
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.

Micropipettes
These fixed-volume micropipettes dispense a small amount of liquid for speedy, routine dispensing jobs. Plunger tip is color-coded by capacity. They require a tip (sold separately).
Fixed-Volume Pipettors
Good for speedy, routine dispensing jobs, these pipettors use air displacement to dispense the same volume every time. They’re more comfortable to hold than standard pipettes—a finger rest anchors to your hand so they’re easier to use one-handed. Press the ejection button to release used dispenser tips without touching them or changing your grip. Use these pipettors with universal-fit pipette tips. For easy identification, they’re color-coded by capacity.
