Variable volume dispense pumps good for 10 million cycles
The medical IVD market is currently undergoing rapid change that is challenging instrument designers at many levels to meet new demands, something accelerated by the current COVID-19 pandemic. It is a significant and growing market where increased pressure on costs is demanding more efficient testing, maximised throughput, higher speeds and better reliability. Instrument size and the simplification of fluidic techniques has had to be addressed to meet point of care testing services without sacrificing throughput.
Maximising fluidic techniques is clearly an important part of this process and has increased the demands on critical components within it, one of which is the variable volume dispensing pumps. A notable success in this area has been the LPD Series of Variable Volume Dispense Pumps from miniature hydraulics specialists The Lee Company. The pumps are, says Lee, "Proven performers in the medical / IVD market, helping customers to meet today's demands and challenges". Key features highlighted are the size and ability of the pumps to provide a long-life, up to 10 million cycles. This lengthy service life allows users to design the LPD pumps into their systems without a need for periodic service, effecting valuable cost savings.
Unlike typical syringe pumps which require periodic maintenance, Lee says that its LPD Series pumps are not only rated for millions of cycles they are also maintenance-free. Therefore they can be placed where the fluidic requirements dictate that they should be, regardless of the need for servicing accessibility, to offer machine designers greater freedoms from the outset. This also means that the pump can be situated near to the fluid reservoir, reducing tubing lengths and flow restrictions which in turn provides faster aspiration rates, higher throughput and shorter test cycle times. They also feature the added capability of integrating valves and other components into the port head design, which minimises potential leak points and once more increases design flexibility. Having a reliable, long-life pump that can last the life of the overall instrument reduces downtime and service requirements, resulting in important overall cost savings.
The LPD Series pump has proven to be a valuable asset in meeting the growing challenges associated with demanding diagnostic instruments says Lee. LPD pumps are said to be field proven in reagent dispensing, aliquoting, probe washing and sample preparation applications, providing high reliability and dispense accuracy at an economical price.
