ZSM-5 type zeolite Representative functions: deodorization, VOC adsorption, catalyst (support) Structure code: MFI Unit cell composition: Nan[AlnSi96-nO192]･xH2O Pore diameter: 6Å Primary particle diameter: 100nm~ SAR: 200 - A representative high-silica synthetic zeolite, its hydrophobicity increases with a decrease in Al concentration. In particular, those without Al are called silicalite-1 and exhibit high hydrophobicity. - The pore diameter is slightly larger than that of a benzene ring, and it is known to show unique selectivity in catalytic reactions of aromatic hydrocarbons. - ZSM-5 is widely used as a catalyst for petrochemical products and is also utilized as a hydrophobic adsorbent. Additionally, it is a promising material for catalysts used in automotive exhaust purification. - By miniaturizing ZSM-5, improvements in reactivity, selectivity, and adsorption speed as an adsorbent can be expected.

A microreactor is a flow-type reaction process that conducts chemical reactions in microspaces ranging from tens to hundreds of micrometers. A major issue in flow synthesis research is the time it takes to detect each reaction condition when optimizing reaction conditions. Therefore, we have developed a microreactor system for optimal reaction condition search that can quickly identify optimal conditions, based on feedback from the pharmaceutical and chemical research fields. *For more details, please download and view the catalog.*

The automatic nozzle cleaning machine "MAC-III" uses a two-fluid cleaning technology that cleans with only water and air, eliminating the need for any solvents. All that is required is a small amount of water and air. With a touch panel, anyone can easily operate it, ensuring consistent cleaning quality regardless of the operator. Additionally, dedicated holders compatible with various nozzles prevent contact between nozzles. The use of twin nozzles has reduced cleaning time to about half of conventional methods. With powerful cleaning capabilities, it removes solder and dirt that adhere to the surface of nozzles and the nozzle openings, which traditional cleaning methods (ultrasonic cleaning) cannot eliminate. It minimizes damage to the suction nozzles caused by cleaning, and there is no peeling of the black coating. For more details, please contact us or refer to the catalog.
