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.

Bulb Droppers
Squeeze the bulb to dispense liquids one drop at a time. These droppers are also known as transfer pipettes.
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 droppers help you dispense very small volumes. They’re often used with fast-flowing liquids, such as water and gasoline.
Wide tip droppers are good for thicker liquids, such as gel, syrup, and thin paste.
Flexible stem droppers can be curved and bent without kinking to transfer liquids in tight areas.
Removable bulb droppers are easy to clean.
Bellows droppers have a large, accordion-shaped bulb that creates strong suction. They’re often used with viscous liquids.
Paddle droppers have a rigid end that’s used for mixing and spreading.
Droppers with graduation marks have molded markings that won’t fade or wash off.
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 droppers are individually cleaned and bagged to avoid contaminating your sample.

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.

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.
Tips for Repeat Dispensing Pipettors
Dispense a sample many times without refilling your pipettor. These tips are designed for use with repeat dispensing pipettors. Like syringes, they have a piston that presses directly against the liquid inside the tip. This creates more pressure than traditional pipettors, which use air displacement, so these tips are good for dispensing thick or foamy liquids.

Filters for Pipette Tips
Filter out contaminants when dispensing samples in labs and other sanitary environments. These filters come in a box that lets you install them on a pipette tip without touching them. They're sterilized by gamma irradiation—use them once and then throw them away.
The filters are designed for pipette tips with a maximum capacity of 1,000 µL. If using them with a tip of a different size, test the fit before sampling.
Sterile Tips for Repeat Dispensing Pipettors
Dispense a sample many times without refilling your pipettor. No need to autoclave these tips before first use—they’re cleaned and bagged to prevent contamination. Pair them with repeat dispensing pipettors. Like syringes, they have a piston that presses directly against the liquid inside the tip. This creates more pressure than traditional pipettors, which use air displacement, so these tips are good for dispensing thick or foamy liquids.
