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).
Plunger pumps can be used with one hand. Turn the thumbwheel to draw liquid into the pipette then press the plunger for quick dispensing. For gradual dispensing, you can use the thumbwheel.
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.

Bulb Dispensers
Bulb with
Clear Stem
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.
Plastic dispensers resist shattering and denting from impact better than glass and stainless steel dispensers. Stainless steel dispensers are more durable than plastic and glass dispensers. They also withstand high heat. 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.
Dispensers with an injector tip can puncture through a surface to dispense liquid on the inside.
Dispensers with a flat-top bulb can rest standing up to prevent dripping between uses.
