Having worked on laboratory design for quite a number of years now, I have seen a marked change in the types of fume hoods which are on the market and which are in demand from scientific and education facilities. The change has fallen in line with the advancement of science and we no longer have a need for such powerful fume hoods as we once did. This evolution of science sees us rarely require the use for a high powered chemical fume hood as we have smarter and more efficient ways of of conducting experiments. As a result of the…
