Air-Powered Constant-Flow-Rate Pumps
Commonly called piston pumps, these are often used in high-pressure applications, such as hydrostatic testing of pipelines, tanks, and valves. Flow and outlet liquid pressure can be controlled by varying the air pressure. To calculate discharge liquid pressure, multiply the air pressure by the ratio shown in the table. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber.
Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

Electronic Pipette Pumps
Pipette for hours on end—these ergonomic pipettors maintain even flow with just the push of a button. With a set speed, you can carefully monitor the quantities aspirated and dispensed. Choose from six aspirating and dispensing speeds—dispense as fast as 5 ml per second. Choose a higher speed when working with viscous liquids. An LED display shows your speed and battery status. To ensure contamination-free pipetting, the nose on these pumps is autoclavable.
