Each pull of the trigger releases a set amount of liquid, making these guns useful for repeated dispensing applications. They have plastic barrels, which are durable and can be used with a variety of liquids. Attach a needle with a luer lock connection and twist it to secure.

Fill and dispense 96 wells all at once. These fillers are best for transferring 50 to 100 microliters per well. Connect them to a 30 ml syringe (not included) to create suction to draw up the liquid from the sample tray. Then use the syringe’s plunger to push the liquid into your wells. You can also use these fillers to remove excess liquid from your well plate.

Note: To maintain the vacuum needed to transfer liquid, you’ll need at least 75 ml in the sample tray.

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.
