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).

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.

Fill eight or more reservoirs with the same, precise amount of liquid in one go. These pipettors are often used to fill every well on a well plate and for other repeat tasks. Using air displacement, each channel on these pipettors draws or dispenses a set volume when you press the plunger. Changing the volume is as easy as twisting the knob until the display shows the right setting. Each channel is individually calibrated, so you can trust that they’re accurate. If you need to recalibrate the pipettor, use the included calibration screw. Rotate the body 360° to align the channels with your well plate or reservoir.

A finger rest makes them more comfortable to use one-handed than standard pipettes. Without changing your grip, you can set your desired volume, slide the lock to secure the setting, and press the plunger. When you're done, push the ejection button to release your tips without touching them. For easy identification, the plungers are color coded by capacity. All come with a shelf-mounting bracket for storage.

Use these pipettors with universal-fit pipette tips.

Transfer eight or more equal samples at once with the push of a button. Compared to manual pipettors, these pipettors dispense using a motor to improve accuracy and reduce fatigue. With an adjustable finger rest and a shape that fits easily in your hand, they’re designed to keep your hand from getting tired. They use air displacement to draw in and push out samples in precise amounts. They’re often used to fill every well on a well plate and for other repeat tasks.

Use the buttons and LCD display to adjust the dispensing volume and select from a variety of functions. You can set these pipettors to mix samples, handle thick and foamy samples, and change speed to slowly dispense gels. When you’re done, tap the ejector button to discard the tip without having to touch it.

Use with universal-fit pipette tips.
