Fixed Volume Dispense Pumps

Lee Fixed Volume Dispense Pumps are solenoid-driven, chemically inert, positive displacement pumps, which provide accurate and repeatable dispense volumes in a small lightweight package. Models are available for a wide range of dispense volumes.

Dispense Pumps - Fixed Volume

Providing accurate and repeatable dispense volumes of 10 to 25 µL. Requiring a simple square wave electrical signal for operation, the pumps aspirate fluid when energized and dispense fluid when de-energized.

These pumps are generally used in medical and scientific applications, in markets such as in vitro diagnostics, human genomics and biotechnology. The following general performance characteristics are offered in this product platform:

  • Chemically Inert
  • Self-Priming
  • High Dispense Accuracy and Repeatability
  • Low Power Consumption

Each pump is 100% functionally tested for performance and designed using materials that ensure consistent long-term performance. The Lee Company can customize the performance of a pump to meet specific application requirements. Please contact DenisDePloeg for additional technical assistance and application information.

Variable Volume Dispense Pumps

Lee Variable Volume Dispense Pumps are stepper motor-driven, positive displacement pumps that feature unparalleled reliability and performance. Variable Volume designs are maintenance-free and offer self-priming and long life expectancy.

Dispense Pumps - Variable Volume

Their size, weight and maintenance free design allows for the pumps to be positioned where the fluidic requirements dictate, regardless of accessibility. The pumps can be customized for a variety of performance characteristics, feedback options and port head materials.

The standard performance model is equipped with a home sensor, whereas most high performance models include a home sensor and encoder for more demanding applications. These pumps are generally used in medical and scientific applications in markets such as in vitro diagnostics, human genomics, biotechnology and analytical chemistry. The following general performance characteristics are offered in this product platform:

  • Maintenance Free Design
  • Long Life Expectancy
  • Self-Priming
  • Wide Range of Dispense Volumes
  • High Dispense Accuracy and Precision

Each pump is 100% functionally tested for performance and designed using materials that will ensure consistent long-term performance. DenisDePloeg can customize the performance of a pump to meet specific application requirements.
