• Testing Equipment and Devices

The "microfluidic chip" can achieve long-term hydrophilization of the entire flow channel without affecting the bonding surface by performing hydrophilization treatment while in a bonded state. Additionally, experimental results from liquid delivery tests have confirmed that there are no issues with long-term hydrophilization of the microchannel or with changes over time. [Features] ■ Surface treatment coating by gas-phase processing ■ Long-term hydrophilization of microfluidic chips *For more details, please refer to the PDF document or feel free to contact us.

• Testing Equipment and Devices

The "Standard Microfluidic Chip" is a microchip that has been finely processed to be suitable for lab-on-a-chip applications. It features micron-level channels and holes that are finely processed on a microchip measuring a few centimeters square. The lab-on-a-chip technology, which conducts various chemical reactions and analyses using these microchannels and microarrays, has the advantage of requiring only small amounts of samples and reagents, enabling experiments and analyses to be performed in a short time. This has led to increasing attention on applications such as microTAS (micro total analysis systems). To allow you to try out such finely processed microchips, we have prepared kits and accessories in addition to the five requested channel pattern chips. Please experience the smooth, non-smearing channels made possible by our unique manufacturing method, which could not be achieved with conventional lithography-based chips.

• Testing Equipment and Devices

Our injection molding materials are resin compositions made from polypropylene-based resins and elastomers. The main feature is their excellent precision transferability, allowing for faithful reproduction of surface patterns with a stamper ranging from 0.3 to 100 μm. As a mold stamper, we use substrates that have been etched on silicon wafers, achieving high-precision mass production of flow path molded products by accurately reproducing the unevenness of silicon molds. As a material characteristic, it is possible to join multiple structures without the use of adhesives, enabling the creation of bonded structures and micro components. 《Examples of Resin Microchip Production》 - Well chips - Microfluidic chips - Micro-layer fluid chips - Micro-pillar chips *Please download the PDF to view the technical introduction and production examples.
