The presence of a cabinet is considered the main condition for all laboratories where work with chemical components takes place. It is needed to protect against exposure to hazardous substances and reagents. The laboratory cabinet protects against the leakage of harmful chemicals. Other types allow you to store the necessary laboratory inventory in the required conditions. A rating of the best laboratory cabinets will help you choose the right one.
The fume hood is a laboratory design that looks like a closed chamber with exhaust ventilation. It is designed for storage of volatile substances, for reagents. According to the classification, this furniture is recognized as a semi-open local suction, which is needed in carrying out technological processes within the laboratory.
The traditional type of device has a transparent wall, water, electricity and gas connections. The table top is made of chemically resistant materials. Exhaust models extract air either naturally or mechanically. The best designs protect against the toxic effects of chemicals.
Installing furniture allows you to prevent the negative impact of harmful chemicals and reagents on employees who have to work with them. Their design features prevent leakage.
In practice, open-draft designs are most often chosen for chemical laboratories. These models are absolutely safe for people due to the forced elimination of air. It is then discharged to the atmosphere by passing through the vents.
The material of their manufacture is different. Most often, furniture is made of metal or chipboard. Chipboard structures are considered the most affordable in material terms, but it is prohibited to use them with increased fire hazard. And metal cabinets are highly resistant.
The choice of devices is necessary depending on the laboratory analyzes and reagents used. This affects functionality and design. Therefore, the best manufacturers try to produce equipment of different volumes and materials.
Often the designs contain:
The parameters of products differ depending on the reagents used and the purpose of the laboratory. For example, flammable substances and gases require special explosion-proof designs. And other products are used for operation in non-standard conditions.
What are the types of fume hoods? Among them, the following types stand out:
The comfort of using each type of product is highly appreciated by specialists. Such equipment is also needed to ensure safety. The main thing is that you need to decide in advance which cabinet is better to buy.
Such designs are needed for drying and processing different containers. Ovens help to set the required temperature level, so they can be used to accommodate samples that need a specific setting. They are also used for laboratory glassware.
In appearance, the equipment is presented in the form of a small electric furnace. Its functionality can be wide: drying, calcining, sterilization are performed. The equipment is also used in analytical research. The device operates at temperatures up to 600 degrees.
The description of such structures is approximately the same. They consist of:
The main compartment is used for drying dishes after washing. Typically, laboratories use heat-resistant containers: cylinders, beakers, cones and beakers. To speed up the elimination of moisture, the container is placed inside. The technique contains loading boxes.
Another function is considered to be sterilization, so such equipment is needed for medical institutions. Dental, surgical, ophthalmic devices are processed in it. The air is heated up to 300 degrees, which eliminates bacteria, spores and fungi.
Equipment with a drying function is also used for other tasks:
According to reviews, this type of equipment is also needed in agriculture. It dries grain, fruits, vegetables. With the help of the construction, the materials are burned, vulcanized, hardened. The furniture can be used for a variety of organic and inorganic designs.
Each manufacturer offers many types of equipment. It differs in size, work surface, functionality. How to choose the right option? To do this, you should pay attention to the recommendations presented.
What to look for first? It is important to determine for what conditions the equipment is purchased. For example, for especially dangerous and aggressive components, products with a ceramic or polymer coating are needed.
Many laboratories buy models with high chemical protection. If studies are carried out using alkalis or acids in high concentration, a cabinet with a glass-fiber-reinforced plastic dome is required.
It is imperative to take into account the selection criteria presented, since safety depends on it. If some substances are heated during research, a cabinet with electric heating panels is needed. Usually, they are controlled using touch sensors, so you can set the desired temperature for a specific time.
Wardrobes are for sale, which have built-in sinks, where dishes and equipment are processed. Explosion-proof equipment allows you to work with hazardous gases. To select safe equipment, you should consider what types of research will be carried out.Furniture should be purchased from trusted firms, having previously studied the popular models and the rating of quality devices. It is important that the products have certificates of conformity.
Mistakes in selection can be costly as the safety of the lab staff depends on it. Therefore, it is necessary that there is not only good capacity, but also high reliability.
The laboratory cabinet should be positioned so that water, electricity, vacuum can be connected. The dimensions of the structure are selected based on the area of the laboratory, since if you put a large product in a small room, it will be difficult to work there. This makes it difficult for employees to move.
A small product is not suitable for a large laboratory. After all, it will not meet all the criteria, which interferes with normal labor productivity. Therefore, the size must be suitable.
The constructions are assembled very quickly. It is enough to connect ventilation, water supply, lighting. For this, the appropriate specialists are invited. Ventilation is of particular importance as the furniture will be used for chemicals. This means that safety must come first.
Structures must be serviced regularly. Testing helps to extend the service life as well as ensure safety. The cabinet is inspected every month. There are also annual inspections. Procedures are required to detect damage in a timely manner.
The correct operation of the cabinets is also important. They should be kept absolutely clean. The temperature in the room should be up to 40 degrees, and the humidity should be in the range of 45-75%. It is important that the cabinets are not exposed to mechanical and chemical factors. The load should be no more than 100 kg.
