ZSM-5 type zeolite Representative functions: deodorization, VOC adsorption, catalyst (support) Structural 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 the decrease of 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 the raw material of catalysts for 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 an optimal reaction condition search microreactor system that can quickly find 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. It features a touch panel that allows anyone to operate it easily, ensuring consistent cleaning quality regardless of the operator. Additionally, it uses dedicated holders compatible with various nozzles, preventing contact between nozzles. With the adoption of twin nozzles, the cleaning time has been reduced to about half compared to conventional methods. Its powerful cleaning capability removes solder and dirt that cannot be removed by traditional cleaning methods (ultrasonic cleaning) from the surfaces of nozzles and the nozzle openings. 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.
