Like their pipeline counterparts, borosilicate glass column components find universal application throughout the world's chmical, pharmaceutical, food and drink and allied industries where the advantages of using glass as a basis for the construction of complete process systems has long been recognised:

■ With almost universal resistance to corrosion, a long service life is guaranteed and maintenance is kept to a minimum.
■ Their transparency permits constant visual monitoring of the process at all times.
■ Being inert, the risk of contamination is negligible.
■ Smooth surfaces allow easy cleaning and sterilization and prevent the build-up of solids on the inner walls.

In many unit operations such as reaction, extraction and absorption, the transparency factor of glass column components is a particular advantage. As an example, colur changes in reaction processes are easily monitored, droplet separation in extraction processes can be observed unhinderd and constant visual monitoring of hydraulic performance in packed columns is possible.

Column components are available from DN 80 to DN 1000 with a smaller range of precision bore components available from DN 25 to DN 150 for specific applications where close internal tolerances are essential.
