Case Studies

Improving Droplet Generation & Flow

A microfluidics device developer needed to achieve a specific droplet generation and flow speed, but was unsure about the proper parameters. Enplas designed and proposed a channel geometry solution based on its extensive database, which is more accurate than software simulations or trial and error.

Enhancing Cell Sorting

A developer of a microfluidic lab-on-a-chip device wanted to enhance cell sorting on the device. Enplas’s solution: integrate the electrodes onto the chip instead of on the testing instrument. Enplas’s ability to print or paste electrodes close to micro-channels can enhance sorting efficiency while simplifying instrument design.

Reducing Contamination & Dead Volume

A client needed the ability to use multiple reagents without contamination while reducing dead volume. Enplas incorporated a rotary membrane valve and pump, allowing the client to control over 20 liquids with a single rotational axis, prevent contamination, and minimize dead volume by reducing a multi-valve method to one.

Solutions

Enplas provides solutions that enhance the function of plastic microfluidic chips at all stages of the diagnostic process.

Solutions for Liquid Handling

Hydrophilic Treatment & Stop Valves

Looking to improve the control of samples flowing through your microfluidic device? Enplas can help achieve this via two methods: hydrophilic treatment and stop valves.

Embedded Pumps & Valves

Using multiple pumps and valves to transfer fluids through your microfluidic device? Enplas can minimize the pumps and valves your device requires by incorporating Enplas-designed rotary membrane pumps and valves (RMVP).

Try the RMVP in the comfort of your own site with an RMVP Demo Kit. These kits are a great way to experience the RMVP’s versatility and see how it can minimize instrument sizes while maximizing fluid-handling performance. Click here to request a demo.

Solutions for Post Processing

Micron-Sized Outlets

Transferring sorted cells to a device using pipettes? Why not directly dispense with the device instead? Enplas can add micron-sized outlets (“side open channel”) to the perimeter of your device to accurately dispense sorted cells.
