Standard Laboratory Furniture Configuration

Laboratory furniture configuration selection

In the construction of the laboratory, furniture design and selection must be carried out according to the laboratory work content, environmental conditions and specific requirements. The layout, function and flexibility design of laboratory furniture is one of the important components of the experimental building design.



Laboratory furniture is classified by function

According to functions, laboratory furniture can be divided into test benches and test cabinets.

1.Test benches include: physical and chemical test benches, instrument benches, overhead platforms, washing benches, sampling benches, high temperature benches, etc.

2. Laboratory cabinets include safety storage cabinets, medicine cabinets, drug cabinets, utensil cabinets, fireproof cabinets, filing cabinets, lockers, specimen cabinets, sample cabinets, gas cylinder cabinets, etc.

Laboratory furniture is classified by material

According to different materials, laboratory furniture can be divided into wooden structure, steel-wood structure and all-steel structure.

1. Wooden furniture is mainly made of man-made panels, with rich colors and strong personalization, suitable for users who pursue individuality, but its moisture resistance and load-bearing capacity are slightly weaker, and it is not suitable for humid laboratories and environments with high load-bearing requirements.

2. The steel-wood structure furniture is composed of a metal frame and a wooden cabinet. The test bench can be equipped with a movable cabinet or a fixed cabinet, which is cost-effective, but with a single style, suitable for users who pursue economic benefits.

3. The steel furniture is made of cold-rolled steel plate after phosphating and pickling, and the surface is baked with epoxy resin. It has good load-bearing performance, sturdiness and durability, and strong overall performance, suitable for users with sufficient budget and high requirements.

Laboratory furniture is classified by structure

The test bench can be divided into fixed test bench, suspended test bench, split test bench and mobile test bench according to different structures.

1. Fixed test bench: A traditional arrangement when the test bench is fixed, the floor cabinet supports the table, which is not flexible enough.

2. Suspension test bench: The cabinet of the suspension test bench is on the floor metal frame, which has good moisture resistance and flexibility. The cabinet can be rearranged without affecting other parts of the workbench system.

3. Split test bench: The water and electricity service system of the split workbench and the test bench are two parts of the split. They are separated and can be combined organically. The test bench can be easily moved and rearranged without the need for new water and electricity. The system is more flexible, suitable for users who distribute purchases or reserve development space for the future, and is one of the mainstream products for future development. This kind of test bench is more expensive.

4. Mobile test bench: The mobile test bench is equipped with wheels, which provides users with some flexibility to create and change their own laboratory space. The objects on the mobile workbench can be easily moved from one place to another. Many desks, carts, and workbench objects can be easily moved from one place to another. Many desks, carts, and workbench objects can be adjusted vertically to be more ergonomic.

Remarks: The initial cost of the mobile test bench is higher than that of the fixed test bench. If the fixed workbench is combined with the mobile workbench according to the test needs, the cost can be reduced and flexibility can be maintained.

According to the layout of the test bench

1. In-line shape: The test bench adopts in-line layout, which is suitable for small laboratory or large laboratory side bench.

2. Type L: The test bench is arranged in parallel with the two adjacent walls of the laboratory with maintenance access, suitable for precision instrument rooms.

3. Peninsula type: One end of the test bench is against the wall, suitable for large-scale laboratories and physical and chemical rooms, and the space utilization rate is high.

4. Island type: The test bench is arranged in the middle of the laboratory to facilitate the work and escape of the test personnel, and the efficiency and safety are relatively high.

Test Bench Size

1. Depth:

The depth of the standard test side table is 750mm;

The depth of the standard central table is 1500mm;

The depth of the precision instrument table depends on the type of the instrument, the depth is generally 800~1000mm

2. Height:

The test bench generally has two heights of 760mm and 840mm. The 760mm high test bench is suitable for sitting operation, and the 840mm high test bench is suitable for standing operation.

3. Length:

The length of the test bench is determined according to the test needs, generally a multiple of 750mm, preferably not more than 4500mm.

The characteristics of the laboratory cabinet

1. Safe cabinet storage

According to the different storage items, it can be divided into drug cabinets, explosion-proof cabinets, acid cabinets, volatile reagent cabinets, etc. According to different uses, there are also different sizes, divided into independent storage three-dimensional cabinets and cabinets placed under the detox cabinet. The drug cabinet is used to store toxic substances and needs to be equipped with double locks to adjust the temperature and humidity.

Explosion-proof cabinets are used to store flammable and explosive items with automatic door closers and explosion-proof doors. There are 30, 60, 90 and other levels, respectively, which means that even if a laboratory fire occurs, the contents of the cabinet are within 30min, 60min, and 90min. It will not explode to gain time for fire fighting or evacuation, protect personnel safety and reduce the risk of laboratory damage.

Acid cabinets are used to store acidic reagents and are generally made of polymer materials. The most common material is polypropylene.

The volatile reagent cabinet is used to store volatile reagents. Generally, the reagent cabinet is equipped with a filter and a small fan. The volatile gas can be periodically pumped out and filtered by the filter to be discharged outside the cabinet to prevent the volatile gas from accumulating in the cabinet for a long time and corroding the cabinet. May cause other dangers. According to the different storage items, different filters can be selected.

2. Medicine cabinet

The medicine cabinet is an indispensable storage cabinet in a chemical laboratory. Chemical reagents are mainly placed. Chemical reagents must be placed according to the classification of solid, liquid, organic, inorganic, acid, alkali, salt, etc., which is easy to find and safe. The medicine cabinet can be equipped with glass doors, and the cabinet body should also have a certain load-bearing capacity and corrosion resistance. The medicine cabinet is divided into drawer type, step layer type or liftable layer type.

The size is generally: 900mm(width)x500mm(depth)x2000mm(height)

3. Sample cabinet

The sample cabinet for placing various test samples can have compartments and label partitions, which is convenient for storing samples and searching samples. Some samples need to be stored in a dry place. The compartments can be large or small to facilitate storage of different samples. .

The size is generally: 900mm(width)x500mm(depth)x2000mm(height)

4. Utensils Cabinet

The utensil cabinet is used to store cleaned glassware. The laminates are divided into stainless steel laminates or anti-double special laminates. The stainless steel laminates are of higher grade and expensive. The laminates are fixed to the cabinet with guide rails and can be pulled out at will. It is convenient to store glassware, and the layer plate has holes, and the position can be adjusted according to the size of the container. The utensil cabinet is well ventilated and easy to clean and dry.

The size is generally: 900mm(width)x500mm(depth)x2000mm(height)

5. Gas cylinder cabinet

Gas cylinder cabinets are used to place gas cylinders. Because gas cylinders are high-pressure containers, they are dangerous. For safety reasons, gas cylinder cabinets are generally made of steel and equipped with alarms. According to different gases, they are divided into flammability alarms and non-flammability alarms. The flammability alarm is better with explosion-proof function, and an explosion vent is set on the top of the cabinet. Gas cylinder cabinets are generally divided into two specifications, single bottle and double screen.

Dimensions are: 450mm (width) x500mm (depth) x2000mm (height), 900mm (width) x500mm (depth) x 2000mm (height)
