Microfluidic Devices – Small Solutions to Important Problems

The field of microfluidics requires the design of systems for which small volumes of fluids will be handled, such as microfluidic devices that have dimensions starting at millimeters in size and smaller. The science of designing, manufacturing, and formulating microfluidic devices and processes requires handling volumes of fluid on the order of a Nano liter, which is a billionth of a liter, or a Pico liter, which is a trillionth of a liter.

Microfluidic Chips

A microfluidic chip is a set of micro-channels etched or molded into a material such as silicon, glass, or polymer that are connected together for a specific function such as mixing, sorting, or pumping. Through the chip, inputs and outputs are pierced together, creating a network of micro-channels that can interface between themselves and the macro- and micro-worlds. Liquids or gases are then injected into these holes and removed from the microfluidic chip through tubing or syringe adapters with external systems such as a pressure controller, a push-syringe, a peristaltic pump, or through more passive ways such as hydrostatic pressure. Micro-channels can have the same characteristic size as biological cells which can play an important role in areas such as drug screening and cell biology research.

Microfluidic Slides

PEP microPEP produces microfluidics slides to the dimensions of 25mm x 75mm x 1mm thick and has manufacturing capabilities that range from small volume embossed slides to high volume injection molded slides. Our proprietary mold frame systems are built to meet unique lab slide/chip configurations, modulate form factors and meet very demanding technical requirements.

We also use microfluidic devices for micro insert molding and assemblies, complex micro injection molding, and micro stamping techniques and technologies. Micro-molding is a very unique injection molding process that requires a specialized molding machine capable of delivering high injection speed, high injection pressure, precise shot control, and an ultra-fine resolution geared specifically for micro components.

Microfluidic Possibilities

As the end result of microfluidics engineering is producing small devices that precisely meter and deliver small amounts of fluid from dispensing devices, PEP microPEP has primarily manufactured devices for drug delivery, genomics and drug discovery lab equipment. However, we are manufacturing more and more sophisticated microfluidics components every day as single units in small molds.
