Bulb Droppers


Standard	Fine Tip	Wide Tip	Flexible Stem	Bellows	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.

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.

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.

Disposable Droppers

Use these glass droppers once and then throw them away to reduce the risk of cross contamination. To control the flow, cover the open top with your thumb.

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.

Pipette Tip Filters

Pipette Tip Not Included

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.

For Maximum Pipette Tip Capacity—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.

Universal-Fit Pipette Tips


Pipette Tip	Rack

Attach these tips to the end of your pipettor to transfer small amounts of liquid. Choose tips that match the capacity range of your pipettor. You can autoclave them before use, but you should dispose of them after use.

Rack—Racked pipette tips come set upright in a storage box, so they’re ready to attach to your pipettor with one hand.

Ready to use, these tips don’t need to be autoclaved before you push them onto the end of your pipettor. They come cleaned and bagged to prevent contamination. Choose tips that match the capacity range of your pipettor. They should be disposed of after use.

Pipette Tips with Liquid-Resistant Coating—Tips with a liquid-resistant coating make sure as little of your sample as possible sticks to them. The coating repels water, and the surfaces are free of grooves, rough spots, and other imperfections that could trap your sample.

Rack—Racked pipette tips come set upright in a storage box, so they’re ready to attach to your pipettor with one hand.

Wide Tip—Wide tips work well with paste, gels, syrups, and other thick liquids that are difficult to pipette.

Polyethylene Filter and Polypropylene Filter—Tips with a filter protect your pipettor from contamination if your sample creates aerosols or splashes. They also prevent damage to your pipettor’s seal from harmful acids and corrosive solutions.
