The IVD market is undergoing a transformation that is challenging instrument designers at many levels. Increased cost pressures from new reimbursement schedules demand more efficient tests, not only with sample and reagent usage but also in reliability and speed. The instrument size and simplification of fluidic techniques must be addressed to accommodate point of care testing services without sacrificing throughput. With the market landscape evolving, so is the demand for smaller specimen samples used to aliquot and deliver reagents needed to achieve a high degree of accuracy and precision.
Increasing demands on IVD instruments present many challenges for instrument designers, but selecting a dispense pump doesn’t have to be one of them. The Lee Company’s LPD Series variable volume dispense pumps offered by DenisDePloeg feature a stepper motor driven, positive displacement design that provides unmatched performance and reliability at an economical price. Equipped with a home sensor for end of stroke positioning and a rotary optical motor encoder for piston movement feedback, our pumps provide unparalleled dispense accuracy and precision. These elements, together with a unique drivetrain design and wear-resistant materials, enable the pumps to achieve consistent performance for a minimum of 10 million cycles. LPD Series pumps are available in a wide range of dispense volumes and material options. They also feature the added capability of integrating valves and other components into the port head design, minimizing potential leak points and increasing design flexibility.
In addition to test speed and reliability, reducing downtime is also an important consideration in instrument design. Unlike typical syringe pumps, which require periodic maintenance, LPD Series pumps are completely maintenance free and rated for millions of cycles. This enables our pump to be placed where the fluidic requirements dictate, regardless of accessibility. By placing the pump near the fluid reservoir, tubing lengths and flow restrictions are reduced, which in turn provides faster aspiration rates, higher throughput and shorter test cycle times. Having a reliable pump that can last the life of your instrument will reduce downtime and service requirements, resulting in an overall cost savings.
Lee LPD Series pumps are field proven in reagent dispensing, aliquoting, probe washing and sample preparation applications, and provide high reliability and dispense accuracy at an economical price. With the LPD Series pump leading the way as fluidic requirements advance, so does the need for components to offer the design flexibility for use in point of care platforms.
