Polypropylene Fume Hoods

      Fume Hoods are always a fixture in industrial and academic settings to capture and exhaust toxic vapors which result from experimentation in a laboratory. Their most important function is to protect the student or technician, as well as the environment. However, there are many instances where the reagents or products also require special conditions, whether it be increased ventilation, or a completely non-metallic work surface. Trace Metal Analysis and High Acid Digestion are two systems where a polypropylene hood is necessary for precise, safe testing.
Trace Metal Analysis to identify trace metals in various materials to the ppm, ppb and ppt level has many applications. Medical laboratories do blood and urine testing to detect toxic or deficient levels of particular metals in the body. Marine biologists look for trace metals in algae and other aquatic organisms to determine the effect of their presence on growth and proliferation. Forensic scientists can treat skin with a test solution and illuminate residual metal with UV light, determining the presence of metal, the type, weight and duration of contact. These analyses are so precise that the experimentation must be done in a completely non-metallic environment.

      Likewise, High Acid Digestion is used to analyze soil and rock samples by first dissolving silicate minerals. Basically, it is a process which breaks down a complex substance into volatile gases and simple salts. Various chemical methods can then be used to accurately determine the concentration of each element. Digestion techniques can also be used to test the integrity of plastic laminate materials used in industry and construction. Fume hoods with metal components are contra-indicated for these types of analysis due to potential corrosion.


Features of the Polypropylene Hood include:

1) White polypro worksurface, cupsink, gooseneck and service fixtures.
2) Flame retardant lined electrical components.
3) Twenty amp duplex outlets with fume-tight covers
4) Top-located fluorescent lighting with translucent polypro window – light switch on front of hood.
5) White polypro ceiling enclosure, 3-sided to nine foot ceiling.
6) Meets ASHRE 110 requirements.



Polypropylene fume hoods and casework are also appropriate for industries using  sophisticated electronic and semiconductor equipment.

Saving Energy with Smart-Sash®

Fume hoods are essential components of research facilities, whether they be pharmaceutical, medical, industrial, biotechnical or education-based. They serve multiple purposes, the most important being to protect workers in the lab from breathing harmful vapors. Unfortunately safety comes at a price, and it has been estimated that one fume hood running for 24 hours a day uses as much energy as two single homes.

In order to maximize energy conservation and increase laboratory safety, Jamestown Metal Products has developed Smart-Sash®. This is a fully automated, programmable system which opens and closes the sash completely hands free. Whenever a researcher enters the designated field of operation in front of the fume hood, the sash will automatically open, and likewise will close 15 to 20 seconds after technician steps away. This eliminates the uncontrollable human factor, optimizing safety and efficiency.



Features include:

  • Electronic gear motor coupled to the chain and sprocket sash counterbalance system.
  • Direct drive to sash chain allows smooth uninterrupted up and down motion.
  • Sash closes within 20 seconds after operator leaves the front of the hood.
  • Able to be retrofitted on JMP or non-JMP bench hoods.
  • Operator can stop the sash opening at any time and re-position manually.
  • Meets ANSI/AIHA Z9.5-2003 specifications.
  • Minimizes exposure by returning the sash to the closed position when not in use.
  • Low volume audible pulses alert operator of sash closure.
  • Prevents cross contamination between hoods.
  • Up to $2,561 annual savings per hood.
  • Aerodynamic sash handle allows for the containment of harmful fumes during rapid sash movement.

    From organic chemistry experiments in a university setting, to drug synthesis in a pharmaceutical lab, Smart-Sash® is unparalleled in its increased safety, efficiency and energy conservation.
