Lab chemical Reagent storage cabinets for corrosives ,acid,,base,solvent

When the laboratory chemical cabinet is used to store corrosive substances such as acids, alkalis and solvents, the following requirements must be met:

1. Chemical lab reagent cabinet material

Corrosion-resistant materials should be selected, and the common ones are as follows:

1. Polypropylene (PP) : has excellent corrosion resistance, can resist the erosion of most acids, alkalis and organic solvents. Its strength is high, not easy to deform, and the insulation performance is good, can avoid the danger of static electricity.

2. Polyvinyl chloride (PVC) : has good tolerance to many corrosive substances, especially acids and bases. The price of PVC chemical cabinet is relatively economical.

3. Stainless steel: For some highly corrosive substances, a specific type of stainless steel chemical cabinet can be selected. Stainless steel has good strength and corrosion resistance, but the cost is higher.

II. Chemical lab reagent structural design

1. Ventilation system: In order to prevent the accumulation of harmful gases caused by volatilization of corrosive substances, the chemical cabinet should be equipped with a good ventilation system. Vents are usually located on the top or side of the cabinet and can be connected to laboratory ventilation ducts or separate ventilation equipment.

2. Laminate: The laminate should have corrosion resistance and can be adjusted in height to adapt to different sizes of containers. A corrosion-resistant mat, such as a polypropylene mat or a rubber mat, can be laid on the laminate to prevent damage to the cabinet when the container slips and leaks.

3. Door lock: Equipped with a reliable door lock to ensure that the chemical cabinet can be safely closed when not in use to prevent unauthorized personnel from contact with corrosive substances.

Three, Chemical lab reagent safety mark

1. Obvious safety signs should be posted on the outside of the chemical cabinet, indicating the type of corrosive substances stored, dangerous characteristics and emergency treatment methods.

2. The identification should be clear, eye-catching and easy to identify to remind laboratory personnel to pay attention to safety.

IV. Chemical lab reagent precautions for Use

1. Classified storage: different types of corrosive substances should be stored separately to avoid mixing and causing chemical reactions. For example, acids and bases should be stored in separate cabinets.

2. Sealed container: Corrosive substances should be stored in a well-sealed container to prevent leakage and volatilization. The container should be marked with information such as the name, concentration and expiration date of the substance.

3. Regular inspection: Regularly check whether the sealing, ventilation system and safety mark of the chemical cabinet are in good condition. If the problem is found, it should be repaired or replaced in time.

4. Personal protection: When taking corrosive substances, wear appropriate personal protective equipment, such as gloves, goggles and protective clothing.

In short, choosing the right laboratory chemical cabinet is crucial for the safe storage of corrosive substances. In the process of use, safety operation procedures should be strictly observed to ensure the safety and health of laboratory personnel.
