For the study of high-speed reaction kinetics! Stop-flow device SX20 [500 microseconds]

A stopped-flow device optimal for steady-state and reaction kinetics studies!

The SX20 stop-flow device from Applied Photophysics is used to study the transient steady states of fast liquid-phase chemical and biochemical reactions initiated by the rapid mixing and stopping (stop-flow) of reactants. Spectroscopic probes such as absorbance and fluorescence are employed to observe the progress of the reaction by recording changes in the intensity of the spectral signal as a function of time. The general upper limit of reaction rates that can be measured using stop-flow spectroscopy is approximately 2000 s⁻¹. However, by utilizing the small volume cells adopted by the SX20, it becomes possible to measure reaction rates exceeding 3000 s⁻¹. *For more details, please download the PDF or feel free to contact us.*

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.

In recent years, as the importance of data integrity (DI) compliance in GMP environments has increased, there has been a growing call to deepen understanding of 21 CFR Part 11. This content introduces an on-demand presentation that organizes the background of Part 11, its relationship with DI, and its positioning in CSA guidance, while explaining the basic concepts of electronic records and electronic signatures. ■Content - Background and basic concepts of Part 11 - Relationship with data integrity (DI) - Positioning in CSA guidance - Basic requirements for electronic records/electronic signatures *This content is based on information as of March 17, 2026. *The information provided is intended for general informational purposes and does not guarantee specific compliance or suitability.
