MICRO PUMPS

LEE MICRO PUMPS

Lee micro pumps are engineered to provide maximum reliability for positive fluid displacement in diagnostics applications, including reagent dispense, aliquoting, probe washing, and sample preparation.

Lee Pre-Set and Variable Volume Pumps are the solution for automated chemistry systems. Designed for “install and forget” operation with outstanding features and performance.

• Standard volume ranges: 50 µl, 250 µl, 750 µl per full stroke
• Full volume dispense as fast as .3 seconds for Pre-Set Pumps, 1
• second for Variable Pumps
• Low Power Consumption means less heat in the cabinet to manage
• Long Life — Millions of cycles
• Compact — Made small to fit inside the machine, near the chemistries
• Light Weight — Made light to fit on moving arms, gantries, etc.
• Robust construction
• Many custom configurations possible
• 100% inspected and function tested

Lee Variable Volume Pump

The LPV Series Variable Volume Pumps are positive displacement pumps that feature unparalleled reliability and consistent performance. These micro pumps are ideal for replacing conventional syringe and peristaltic pumps. Also, the low power consumption, light weight and small size permit the pump to be located wherever the fluidic requirements dictate, regardless of maintenance accessibility.

• Compact Size
• Low Power Consumption
• Available in 50, 250, 750 and 1,250µL Volume Sizes.
• Maintenance Free
• Self Priming
• Custom Porting Options Available
• Cv: 0.04%
• Dispense Increments as Small as 0.1µL
• Manifold Mountable Option

Lee Fixed Volume Pump

These general purpose micro pumps are widely used for medical and scientific applications such as blood chemistry instruments, drug dispensing, and blood pressure monitors. They are also used extensively in robotics, computer peripheral equipment, textile printing machinery, and numerous other applications. LPLA Series solenoid pumps offer the following features:

• Operating pressures up to 30 inches of water
• Low power consumption of 2 watts
• Response times as fast as .25 seconds
• Integral valve seat to prevent free flow
• Operating cycle life of at least 10 million cycles
• Low internal volume
• 5, 12, and 24 vdc options
• Tube connection and manifold mount capabilities
