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.

The simplest form of a pipette pump, these bulbs let you control flow as you quickly draw and dispense liquid. Use them with a pipette.

Pair these pipettes with a pipette pump to transfer measured streams of liquid.

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.

Cover the top opening with your thumb to control the flow of liquid one drop at a time.

Twist the knob to change the precise amount these pipettors draw in and dispense.

Save time dispensing the same amount. Compared to fixed-volume pipettors, these pipettors let you dispense up to 49 samples on a single draw.

Fill eight or more reservoirs with the same, precise amount of liquid in one go. Using air displacement, each channel on these pipettors draws or dispenses a set volume when you press the plunger.

To make sure these reservoirs arrive sterile, they've been irradiated, individually bagged, and marked with a lot number.
