Components

Adjustable Shelf: An adjustable shelf is a standard middle or upper cabinet shelf with platform-like panel design that rests on shelf pins or pegs that move within the frame of the storage cabinet. A series of pre-drilled holes on the inner sides of the cabinet allow the shelf to adjust position while maintaining level placement for safe use.

Airflow Meter: Airflow monitors are included with fume hoods to monitor the airflow under the fume hood, when in use, to detect signs of low airflow or other potential hazards for optimal performance and safety.

Anti-Corrosive Metal Components: Metal components are coated with epoxy, polymer, or other protective coating to prevent corrosion and maintain high-quality support.

Base Cabinet: A base cabinet is the lower portion of a fume hood assembly, typically containing a two-door or combination storage layout, with chemical-resistant work surface covered by the fume hood.

Bypass Grille: A bypass grille is an opening in the fume hood above the door or sash. As the door or sash is opened, it covers part or all of the bypass grille opening, helping to direct airflow and limit increase in face velocity as the fume hood sash is closed.

Cold Water Cup Sink: A cold water cup sink is a small sink built into the work surface of a fume hood assembly that operates to produce cold water only.

Double Swing Doors: Double swing doors are hinged double doors on a base that open to reveal the interior cabinet storage space.

Drive Sash: The drive sash is the door that opens and closes to contain the workspace under a fume hood, forcing the “drive” of airflow away from the user and toward the vent, fan, or duct system.

Energy Ports: Energy ports are found on the mobile fume hood station to supply power to the fume hood for safe operation.

Full-Length Finger-Lift Shaft Drive Sash: A full-length finger-lift drive sash is a handle-like element on the lower edge of the sash door, running the complete length or width of the sash for balanced support to allow easy lifting access to the interior of the fume hood workspace. The design reduces risk of the sash opening unevenly by balancing the pressure applied as the sash is lifted open.

Flow Monitor: A flow monitor is an airflow monitor attached to fume hoods to detect when the airflow is insufficient while the fume hood is in use.

Fixed Shelf: A fixed shelf is usually a bottom shelf in a cabinet or frame that has a fixed, non-adjustable position because it comprises the base portion of the overall frame and adds to the stability of the storage unit.

Gas Fixture: Gas fixture refers to the nozzle and valve assembly, usually near a sink on a science lab workstation countertop, designed to provide gas for use in experiments and lab activities. The gas fixture will connect to gas supplies, usually placed within the base cabinet.

GFI Outlet: A GFI or GFCI outlet is an electrical outlet designed to cut power when the internal mechanism detects electricity flowing in a direction other than the intended path. The design is meant to reduce risk of electric shock, electrocution, and contact with water or other fluids.

Gooseneck Faucet: A gooseneck faucet is a curved faucet design that resembles the neck of a goose or swan, providing a larger workspace underneath the faucet for easier access in science lab settings.

Heavy-Duty Casters: Heavy-duty casters are durable wheels that support the weight of the base cabinet and fume hood, as well as the weight of equipment stored in the cabinet and used on the work surface. The casters provide gliding mobility for easy transport of the mobile fume hood unit.

Hood Inlet Collar: The hood inlet collar is the part of the exhaust system on a fume hood that connects to the duct system in a building, classroom, or lab.

Light Fixture: Fume hoods and fume hood stations often contain a light fixture for illuminating the work surface under the fume hood to improve safe use.

Louvered Front By-Pass: louvered front by-pass refers to the angled vents made in the front of the fume hood unit to allow air to circulate into the fume hood when the sash or door is closed.

Natural Oak Cabinet: Natural oak cabinet refers to the solid oak wood cabinet comprising the base of a fume hood assembly. The oak wood is typically finished for a light oak wood-tone color, and protected by UV or other durable and chemical-resistant topcoat or seal.

Push Handle: Push handles are often built into the ends or sides of mobile storage carts, including the mobile fume hood station. The push handle enables steering and maneuvering while transporting or guiding the mobile fume hood station for safer mobility.

Pull-Out Shelf: Pull-out shelf refers to interior shelves within a base cabinet or similar storage unit that is set on drawer slides to allow the shelf to slide out from within the frame or cabinet but maintain position and support. The design can be similar to a keyboard shelf installed under the work surface of a computer desk, and the shelf may have flat design or raised sides and front to help contain items.

Recessed Kickplate: A recessed kickplate is a protected panel that shields the bottom edge of a base cabinet. The kickplate is recessed, or set back slightly from the front periphery of the cabinet doors, allowing feet and shoes to step closer for better access to the work surface.

Replacement Fume Hood Filter: A replacement fume hood filter is designed to replace the standard included filter in select fume hood products to continue providing health and safety function in science lab and classroom or professional settings. The fume hood filters can handle gas, solid, and liquid chemical substances.

Safety Glass: Safety glass is tempered glass that offers enhanced durability due to a chemical treatment that increases glass strength. The treatment also provides an enhanced safety feature that creates tiny granules if the glass is broken, instead of sharp and dangerous larger pieces.

Sampling Port: A sampling port is a safety mechanism on fume hoods that tests the air for hazardous fumes to inform users when it is safe to open the sash door.

Sash Guide: The sash guide is the customized track-style frame that allows the sash to open or close neatly and securely with each operation.

Single Turret Gas Valve: A single turret gas valve is a nozzle for supplying gas with a single turning mechanism to allow or stop gas flow.

Storage Drawer: Storage drawers are versatile box-like drawers built within the frame of a storage cabinet or base unit. The storage drawers may have individual locks for securing contents when not in use.

T-8 Fluorescent Light: A T-8 Fluorescent Light is a 1”-diameter tube-style Fluorescent light that has two contact points, one at each end, to operate the light and simplify installation or replacement of the bulb. The T-8 Fluorescent light is widely available and has been in use since the 1930s. The bulb is considered energy-efficient.

Construction Materials

Black Epoxy Resin Top: Black epoxy resin top refers to the black work surface on many high-quality science lab tables, carts, and workstations, designed to withstand exposure to typical laboratory chemicals and substances without damage. The epoxy resin top is also able to endure exposure to heat and moisture for easy cleanup and equipment use, and the design eliminates risk of delamination, swelling, or other damage from regular use.
