Bulb Dispensers
 |  |  |  |
Flat-Top Bulb with Clear Stem | With Semi-Clear Stem | With Silver Stem | 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.
Polystyrene Stem and Polyethylene Stem—Polystyrene and Polyethylene dispensers resist shattering and denting from impact better than glass and stainless steel dispensers.
Stainless Steel Stem—Stainless steel dispensers are more durable than plastic and glass dispensers. They also withstand high heat.
Tempered Glass Stem—Tempered glass dispensers resist staining better than plastic dispensers. They also withstand high heat.
Clear—Clear dispensers let you see the liquid inside and confirm the exact volume, unlike silver dispensers.
Semi-Clear Stem—Semi-clear dispensers let you see the liquid inside and confirm the exact volume, unlike silver dispensers.
Stainless Steel Injector Tip—Dispensers with an injector tip can puncture through a surface to dispense liquid on the inside.
Flat-Top Bulb—Dispensers with a flat-top bulb can rest standing up to prevent dripping between uses.

Pipettes with Pump
 |
Bulb |
Transfer measured streams of liquid. Made of borosilicate glass, these pipettes resist chemicals and clean easily for repeatable volume measurements in laboratory and quality-control applications.
Bulb—The attached vinyl bulb draws and dispenses liquid with controlled flow. No separate pumping equipment is needed.

Pipette Bulbs
 |  |
Bulb | Bulb with Control Valves |
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—Vinyl plastic bulbs are more chemical resistant than natural rubber bulbs, helping them resist degrading if you accidentally draw chemicals up into them.
Control Valves—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.
Bulb-Dropper Bottles
 |  |  |
Clear | Amber | Graduations |
Squeeze the bulb to dispense liquids one drop at a time.
Amber—Amber bottles keep light-sensitive contents safe from UV exposure.
Graduations—Droppers with graduations help you measure accurately. The marks are engraved, so they’ll still be readable after many uses.

Pipette Pumps
 |
Bulb |
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—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.
