Glass sample holders - improved design Glass ARC bombs are used with peroxides and other chemicals whose decomposition iscatalysed by metal, recent redesign and improved manufacture has allowed us to offer higherquality glass test cells without an increase in their price. Please request more informationfrom THT very small sample chemical or battery component may be tested in the ARC. This method uses a side branch tube for pressure measurement and so is ideal for pyrophoric and other such reactive materials because the complete assembly may be made in a glove box 加速量熱儀（ARC）
