Micropumps: Media supply for cell culture and tissue engineering

This micropump can be used to circulate media or continuously supply fresh media for cell culturing or tissue engineering with greatly reduced risk of contamination over time. The continuously adjustable flow rates are able to actively optimize the media conditions, and the virtually steady flow can minimize the perturbation to cells. Two or more micropumps in parallel allow to formulate new media or produce a define media gradient for cell perfusion. The robustness of the micropumps for continuous supply of culturing media reduces the frequency of manual media exchange. The PET construction of the micropumps is compatible with autoclaving and EtO sterilization as well as culturing media. Therefore, these micropumps provide unique features to your dynamic cell culturing and tissue engineering.

Micropumps: Sample and reagent transfer for medical devices

The compact micropumps meet the increasing requirements of the miniaturization, portability, and low energy consumption of point-of-care devices and other diagnostic instruments. The integration of multiple micropumps allows sequential sampling, mixing and splitting, sample preparation, analysis, and detection in favor of the sample-in-result-out tasks. Directed and activated transport of samples and reagents potentially enhance the reliability of medical devices. The disposable micropumps can significantly mitigate the risk of sample cross contamination, and their low cost  reduces health care expenses of patients. Therefore, these micropumps provide unique features for handling fluids in disposable medical devices for medical diagnostics and other health care solutions.

Micropumps: Sample transport for sensors

The micropumps enable passive and active transport of gas or liquid samples to the sensing components of sensors thus ensuring in situ and accurate monitoring. The small physical dimensions of these micropumps favor the miniaturization and portability of sensors. The particle and bubble tolerance may offer robustness to the fast sample refreshing, and the remote controllability allows these micropumps to be used in hard-to-reach and difficult environments. Therefore, these micropumps are strongly recommended to serve as an integrated component with sensors or as an essential component in more complex unit.

Micropumps: Liquid transport for portable nebulizers

These micropumps satisfy the preferred requirements of portable nebulizers including small physical dimensions, light weight, low energy consumption, as well as easy orientation. These micropumps can be integrated with the nebulizers that are powered with batteries, supply liquids above the nebulizing flow rates, and work equally at various orientations. The passive supply of fluid at defined flow rates ensures continuous and stable dosing for medical nebulizers such as inhalators. Therefore, these micropumps can be integrated with portable nebulizers thus enabling sustained medication delivery.   

Micropumps: Used in small appliances and consumer products

The miniaturized pumps can be installed in small appliances to continuously or intermittently dispense gases or liquids. Examples of these appliances may include steam irons, humidifiers, ˈmoisturizers, and detergent dispensers etc. Additionally, these micropumps may play major roles in consumer products, such as hand-fee disinfectant dispenser and scent diffusers.

Micropumps: Supply and circulate fuel in fuel cells

Portable fuel cells demand smaller components with low energy consumption, reliability, and low cost. Micropumps meet these requirements and thus can be used to continuously pump fuel such as methanol to the cell.  One micropump supplies methanol that will be diluted with water in the cell. A second micropump circulates the fuel mixture for sustained energy production.

Micropump: Electronic Cooling

Traditional cooling approaches, such as impinging air jets, and thermoelectric coolers and direct immersion cooling etc., increasingly falling short in meeting the thermal management challenges in electronic systems, such as in microchip set cooling or electronic control module (ECM). Low power consumption, thin and flat size (including built-in driver) and light weight make our piezoelectric micropump suitable for applications in LED liquid cooling or other electronic systems.
