Is there a specific requirement for the glass thickness of the laboratory fume hood?

Laboratory fume hoods are made of a variety of materials, each with its own unique characteristics and application scenarios. The following are some common laboratory fume hood materials and their characteristics:

1. All steel

Features: The all-steel fume hood is usually made of high-quality cold-rolled steel plate, which is treated with acid phosphating, and the surface is anti-corrosion and anti-acid and alkali, and it is not easy to rust. The countertop can be made of solid core physical and chemical board, epoxy resin board, ceramic board, Qiansi board and other materials. Control panel for electronic display, scientific control. Can use 5mm thick tempered glass window, sliding freely.

Advantages: The all-steel fume hood is durable, strong corrosion resistance, suitable for a variety of experimental environments requiring high strength and corrosion resistance.

Application scenario: chemical laboratory, drug synthesis laboratory, environmental testing laboratory, etc., especially suitable for dealing with corrosive chemicals, strong acids, strong alkalis, solvents, etc.

2. PP (polypropylene) material

Characteristics: PP material is a non-toxic harmless, strong corrosion resistance of environmental protection material. The whole body is milky white, environmental protection and beautiful, and insulation and flame retardant, not easy to aging and discoloration.

Advantages: not easily contaminated with dust, easy to clean, with moisture-proof and waterproof function. Lighter material, easy to move.

Application scenario: It is suitable for laboratories with high cleanliness requirements, such as the experimental environment dealing with corrosive chemicals such as strong acid, strong alkali and salt.

3. Stainless steel

Features: Stainless steel fume hoods are usually made of 304 or 316 stainless steel and have excellent corrosion resistance and high temperature resistance. The cabinet is durable, load-bearing, flexible, easy to disassemble, handle and maintain.

Advantages: Stainless steel surface is smooth, not easy to accumulate dust and stains, easy to clean and maintain. The appearance is modern and simple, which can enhance the overall grade of the laboratory.

Application scenario: Usually used in factories, pharmaceutical factories and other large industrial sites, but also suitable for the laboratory to deal with strong acid, strong alkali and other corrosive experimental environment.

4. Fiberglass material

Features: Glass reinforced plastic (FRP) is the main material of the fume hood, which has excellent corrosion resistance, high temperature resistance and high strength characteristics.

Advantages: Fiberglass fume hood light weight, easy installation, good fire performance, and acid, alkali, solvent and other chemicals have a good resistance.

Application scenario: It is especially suitable for the experiment of some chemicals such as strong acid, strong base and solvent, especially the environment containing volatile chemicals such as chlorine, fluorine and solvent.

5. Other materials

Steel and wood material: combined with the advantages of steel and wood, it has better durability and sound insulation effect.

Aluminum wood or plastic materials: In some specific scenarios, such as biology LABS, these materials may be preferred.

The material of the ductless fume hood: usually metal or composite material, with an internal filtration system for handling harmful gases.

6. Surface material

Solid core physical and chemical board: acid and alkali resistance, moisture resistance, impact resistance, antibacterial easy to clean.

Epoxy resin board: Excellent corrosion resistance and high temperature resistance.

Ceramic plate: high hardness, wear resistance, easy to clean.

PP countertops or PVC countertops: chemically resistant.
