Temperature Range
Vacuum ~ 4.0 MPa
Pressure Range
316 stainless steel
Product Material

Product Introduction

The PX-RC-DRS-A1 is designed for compatibility with mainstream FTIR and UV-visible spectrometers and is equipped with a Raman dome for in situ Raman characterization. Optimized for gas–solid phase studies, it supports conditions from vacuum to high pressure and from ambient to elevated temperatures. Its extremely low internal reactive volume ensures an average gas residence time of less than 2 seconds, making it ideal for transient kinetic experiments and spectrodynamic investigations such as SSITKA and MES.

Product Features

Low Dead Volume Design

Enables transient spectroscopy tests such as SSITKA and MES by minimizing gas residence time.

Photocatalytic Research Capability

Allows introduction of external light sources for photocatalytic experiments under controlled conditions.

Multi-Spectroscopy Compatibility

Compatible with FTIR, UV-Vis, and Raman systems from various mainstream instrument brands.
