Fume Hoods for Laboratory Safety

HEMCO offers the most extensive line of Laboratory Fume Hoods in the industry.

HEMCO UniFlow Aire-Stream Fume Hoods Superstructure features exclusive unitized dual wall construction for total chemical resistance, strength, and durability.

UniFlow Hoods include Low Flow Constant Volume and Variable Air Volume models. Process specific models are PVC, Polypro, Phenolic, or Stainless Steel lined for Perchloric Acid, or Acid Digestion.

  • Laboratory furniture including a wide selection of cabinet styles, countertops, sinks, and fixtures are supplied to meet specific layout designs.
  • Ventilation and safety equipment listed include exhaust blowers, filters, emergency shower booths, and eye/face wash stations.
  • Custom sizes can be easily modified to suit special needs.
  • Performance tested to ASHRAE 110-1995.
  • U.L. 1805 certified for Fume Hoods and Cabinets.
  • SEFA1 Recommended Practices for Fume Hoods.
  • Greener Product Certified.

UniFlow SE Hoods are available in Constant Air Volume (CAV) Air Bypass or Variable Air Volume (VAV), which provide for maximum energy efficiency and user protection.

  • Explosion-Proof models, or CE models for International Electronic Configurations. Standard sizes of 48", 60", 72", & 96" widths.
  • The aerodynamic face opening with air foil provides uniform air flow into the fume chamber.
  • Performance tested to ASHRAE 110-1995.
  • This series of fume hoods is U.L. 1805 certified and is offered in 48", 60", 72", and 96" widths in either constant air volume or restricted bypass models.
  • The new UniFlow Aire-Stream Fume Hood is a high performance fume hood that maximizes user protection and energy savings. The enhanced airflow and reduced turbulence ensures safe operation at lower face velocities.
  • The UniFlow Aire-Stream Fume Hood is constructed entirely of chemical resistant, flame-retardant, non-metallic composite resin materials and featurs an exclusive "Unitized" construction that does not require screws, bolts, rivets, or metallic hardware to assemble. The fume chamber is a molded one-piece white surface with all corners covered for easy cleaning and light reflectivity. This hood is equipped with a 36"-high extended view height, exclusive slotted VaraFlow baffle system, aerodynamic sash lift with perforated air-sweep feature, and molded-in belled outlet collar for reduced airflow resistance.

UniFlow LE Hoods are available in:

  1. Constant Air Volume (CAV) Bypass;
  2. Variable Air Volume (VAV), which provides maximum energy efficiency and user protection;
  3. Explosion Proof models;
  4. CE models for International Electronic Configurations. The aerodynamic face opening with air foil provides uniform airflow into the fume chamber, and through the VaraFlow Baffle System, to the 12"-diameter bell-shaped exhaust collar.
  • LE Low Flow Constatn Volume Fume Hood available in 3', 4', 5', 6', and 8' widths.
  • The HEMCO LE fume hood incorporates a Unitized Superstructure, with non-metallic dual-wall construction for total chemical resistance, strength, and durability. Integral one-piece fume chamber is glass smooth with all covered corners.
  • The VaraFlow baffle system directs the air through the fume chamber and through the exhaust outlet with minimum turbulence and maxiumum airflow efficiency. ASHRAE-110, NFPA-45, U.L. 1805 Classified & SEFA Recommended.

UniFlow "CE" Energy Saving Laboratory Fume Hood

  • A full duty Fume Hood in a compact size, the CE Model is a low-flow constant volume fume hood that offers 50% energy savings over conventional fume hoods.
  • CE fume hoods are offered in 30", 36", and 48" widths.
  • Can be equipped with a wide selection of accessories to meet your specific process needs.
  • CEs are constructed totally of composite resin for superior chemical resistance and can be supplied with or without an exhaust blower in standard or explosion-proof models.
  • Hood is shipped completely assembled and can include a wide selection of accessories that can be factory installed to meet your specific needs. Work surfaces in a variety of materials and a choice of base cabinets including acid or flammable storage are optional as required.

Lifting Latent Fingerprints from Difficult Surfaces

ALMOST ANYONE can find, process, and lift a latent print that happens to be in a logical and obvious place like a door handle, a beer can, or a butcher knife. But sometimes, a latent print is not just sitting there in a logical and obvious place. Sometimes, you have to use your imagination to find the print and your skills to lift it.
