TeleChem’s ArrayIt® brand vacuum pumps (Cat. AVP and AVP220) set a new standard for oil-free laboratory vacuum pumps. Our AVP products are extremely quiet, rugged and durable, and can be used for the full spectrum of microarray laboratory applications including solution filtration, vacuum stations in microarray robots, vacuum manifolds for DNA purification, cleanroom, and many other laboratory applications.
Linear Pump: The activated electromagnet attracts the piston against the return spring, while air is taken into the cylinder through the open inlet valve. When the electromagnet is deactivated, the return spring pushes the piston back, and the compressed air is moved out of the cylinder through the outlet valve.
