I have visited several hundred different laboratories in my career and time after time I see fume cupboards corroding, some in only a few months or years.
Why are fume cupboards (which by their very nature are highly likely to contain corrosive substances) still manufactured from steel?
The simple reason is that it is the easiest material for manufacturers to use. Mild steel with a thin epoxy powder coating has been used for decades now and end-users are often unaware that a more cost-effective alternative is available.
At ISG we use virgin Medical grade Polypropylene which offers 100% corrosion resistance and of course requires no powder coating or painting. We also offer a variety of work surfaces to suit given applications instead of just using Trespa (which is OK for general lab benches but is not the best material for fume cupboards).ALL RESOURCES
