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.

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.
