Column Components Measurement & Controls Column Components In many operations like reaction, extraction and absorption, the transparency of glass is a particular advantage. For such processes a range of column components are available in borosilicate glass which offers many advantages like : Inert to almost all chemicals hence no risk of contamination. Transparency allows visual monitoring of the process, flow patterns, colour changes etc. Almost universal resistance to corrosion Smooth surface permits easy cleaning and prevents fouling. Measurement & Controls In this part we have introduced equipment for efficient measure and control like Digital temperature indicators and controllers, Electro-magnet and timers for reflux control and Liquid level controller.
