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.
