Pipette Bulbs
The simplest form of a pipette pump, these bulbs let you control flow as you quickly draw and dispense liquid. Use them with two hands to ensure they don’t separate from pipettes (not included).
Vinyl plastic bulbs are more chemical resistant than natural rubber bulbs, helping them resist degrading if you accidentally draw chemicals up into them.
Bulbs with control valves are more precise than bulbs without control valves. They have three valves—one empties air from the bulb, one suctions liquid into the pipette, and one empties the pipette.
Pipettes with Pump
Transfer measured streams of liquid.
Bulb pipettes require two hands.

Pipette Pumps
Draw and dispense liquids at a controlled speed. These pumps give you more control of flow than a basic pipette bulb but not as much as an electronic pump. Use them with a pipette (not included).
Bulb pumps have a lever to set both the aspirating and dispensing speeds. Press the button above the lever to blow out any residual liquids.

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.
