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.
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.
Sterile droppers are individually cleaned and bagged to avoid contaminating your sample.

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.

This creates more pressure than traditional pipettors, which use air displacement, so these tips are good for dispensing thick or foamy liquids.
