    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.

    Plunger

    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).
    Plunger—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—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.

    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.

    Paddle

    Squeeze the bulb to dispense liquids one drop at a time. These droppers are also known as transfer pipettes.
    Dispenser Boxes—Droppers with a dispenser box stay organized and protected when they’re not in use. The box has a hinged front panel for easy access to droppers.
    Fine Tip—Fine tip droppers help you dispense very small volumes. They’re often used with fast-flowing liquids, such as water and gasoline.
    Wide Tip—Wide tip droppers are good for thicker liquids, such as gel, syrup, and thin paste.
    Flexible Stem—Flexible stem droppers can be curved and bent without kinking to transfer liquids in tight areas.
    Removable Bulb—Removable bulb droppers are easy to clean.
    Bellows—Bellows droppers have a large, accordion-shaped bulb that creates strong suction. They’re often used with viscous liquids.
    Paddle—Paddle droppers have a rigid end that’s used for mixing and spreading.
    Soda-Lime Glass Stem—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—Sterile droppers are individually cleaned and bagged to avoid contaminating your sample.
    Graduations—Droppers with graduations have molded markings that won’t fade or wash off.
