Chemical fume hoods
Bypass, restricted-bypass and VAV hoods in 1200–2400 mm widths, with airflow monitor and audible alarm as standard. Epoxy, phenolic or stainless liners and worktops.

Our Products
Fume Hoods
Containment you can prove. Every hood we install is commissioned on site with a face-velocity traverse and alarm verification, and you receive the signed report.
Walk-in & floor-mounted hoods
Full-height walk-in hoods for large apparatus, distillation rigs and drum handling, with removable sash panels and floor-level airflow control.
Built in Canada
Microbiological hoods
Class II microbiological safety cabinets for work requiring both product and operator protection, certified at installation and re-certified annually.
Imported · Scientora-specified
Ceiling canopy hoods
Ceiling-mounted canopy and dome hoods in polypropylene and steel, for autoclaves, ovens, muffle furnaces and open sample preparation.
Imported · Scientora-specified
Two-joint articulated arms
50, 75 and 100 mm two-joint extraction arms for bench, wall or ceiling mounting, with adjustable hood, damper and friction joints that stay where you put them.
Imported · Scientora-specified
Three-joint articulated arms
Extended-reach three-joint arms for island benches and instruments that sit away from the wall — the configuration in most of our GC and sample-prep rooms.
Imported · Scientora-specified
Ductless filtered enclosures
Carbon and HEPA filtered enclosures for laboratories where ducting to roof is not possible, with saturation monitoring and a documented filter-change regime.
Imported · Scientora-specified
Vented storage & connections
Under-hood vented acid and solvent storage, exhaust connection collars, dampers, transitions and roof-fan coordination with your mechanical trade.
Built in Canada
Monitors, alarms & controls
Airflow monitors, low-flow alarms, sash position sensors and VAV controllers, commissioned and set to the design face velocity on site.

Why the as-installed test matters
A hood that passes at the factory can still fail in your room. Face velocity depends on the fan, the ductwork, the make-up air, the position of the door and the traffic past the sash. That is why our hoods are commissioned in place — measured, balanced and tested where they will actually be used — and why the report you receive says as installed, not as manufactured.
Replacing a hood in a working laboratory
Most hood work we do is a replacement, not a new build. We phase it: survey and shop drawings first, then a shutdown window agreed with your operations team, containment and dust control during removal, and the new unit commissioned before the room comes back into service. See Lab Renovation for how that runs.
