Pure Epoxy Scaffold for Fume Hood

Quick Answer: The Pure Epoxy Scaffold for Fume Hood is a support fitting for use inside a laboratory fume hood, made of epoxy resin according to its title, on which apparatus and glassware are arranged or held during work in the hood.

What the Scaffold Does in a Hood

Work in a fume hood is often built upwards: flasks on stands, condensers, dropping funnels and receivers clamped at different heights, or bottles and glassware kept towards the back of the hood during a procedure. In fume-hood fittings the word ‘scaffold’ is generally used for a support framework fixed inside the hood for this purpose. The listing does not describe the form of this epoxy scaffold for fume hood use, whether frame, shelf or raised stand, nor its size and fixing, so please confirm these at enquiry; this page covers the purpose and the material named in the title.

Epoxy resin is used for laboratory work surfaces and hood fittings because it is generally resistant to a wide range of acids, alkalis and solvents, is non-porous and tolerates moderate heat. ‘Pure epoxy’ indicates that the part is made of epoxy resin itself rather than of painted or coated metal, which avoids the problem of rust spreading under chipped paint in acid fumes.

Any support inside a hood affects the airflow. Keep apparatus well inside the hood, away from the sash opening, and do not block the slots in the rear baffle through which the hood draws air. Large items sit better on a raised support that lets air pass beneath them than flat on the work surface, and a PP tray under the apparatus catches spills. The exhaust volume itself is set by the hood’s fan and a Duct Damper for Fume Hood; the scaffold should not undo it.

Applications

• Supporting reflux, distillation and filtration set-ups built upward inside the hood.
• Holding reagent bottles and glassware off the work surface during a procedure.
• Replacing corroded metal supports in hoods used with acid fumes.
• Fitting out new fume hoods in pharmaceutical and research labs.

Specifications

Care & Handling

• Wipe spills from epoxy surfaces promptly and rinse; epoxy resists many chemicals, but long contact with strong oxidisers and some solvents can mark it.
• Do not stand items straight from a flame or heating mantle on the epoxy; use a heat-resistant mat.
• Check that the scaffold is firmly fixed before clamping heavy apparatus to it.
• Keep it clear of the baffle slots so the hood’s airflow is not obstructed.

Why Choose LabEquip

Fume hood builders and labs replacing corroded hood fittings are the likely buyers of an epoxy scaffold. LabEquip lists it in General Lab Products; the hood’s internal dimensions sent through the contact page allow the form and fixing to be confirmed.

Frequently Asked Questions

What is a scaffold in a fume hood?

In hood fittings, a scaffold is generally a support framework inside the hood on which apparatus is arranged or clamped. The exact form of this epoxy scaffold, such as frame, shelf or stand, should be confirmed when you enquire.

Why use epoxy instead of metal inside a hood?

Acid fumes corrode steel, and once paint chips, rust spreads beneath it. Epoxy resin is non-porous and resists many acids, alkalis and solvents, so it holds up better in a hood used for corrosive work.

Does a scaffold affect the fume hood airflow?

It can. Any object near the sash or in front of the rear baffle slots disturbs the airflow. Keep supports and apparatus well inside the hood and clear of the slots.

Can hot glassware be placed on epoxy?

Epoxy tolerates moderate heat, but very hot items straight from a flame or heating mantle can mark or crack it. Stand them on a heat-resistant mat until they cool.

Which chemicals can damage epoxy resin?

Epoxy resists most common lab chemicals, but prolonged contact with strong oxidising acids and some solvents can stain or soften it. Wipe spills promptly and rinse with water.

How should apparatus be arranged in a hood with a scaffold?

Place the tallest items at the back, keep work well inside the sash opening, and raise large items slightly so that air can flow beneath them. Keep the sash as low as the work allows.
