The Layout Of The Laboratory Bench Is Crucial
May 22, 2018

The layout of the laboratory bench is crucial, and in an emergency, people can be evacuated as quickly as possible to a safe place, so there is no dead end. Once there is an emergency, the experimenter can choose between two undifferentiated pathways, no matter what they do. The walkway between the experimental stations should be accessible to the corridor, allowing the experimenter to pull out of the laboratory in the shortest possible time.

The Laboratory Bench can be divided into three types, namely, two-sided island, peninsular and one-side wall. The island type experiment station, the experimenter can walk around in the crowd, the activity area is relatively large, facilitate rapid evacuation. The appropriate spacing should be left between the experimental stations, usually not less than 130 cm. But if special configurations (such as storage cylinders, etc.) need to be set in front of the test station, the net distance between the two experimental stations should be at least 160 to 180 centimetres. Due to the adjacent test bench experiment personnel according to the operation of the "back-to-back" essentials, so sometimes can be set up in the middle of the test bench channel separating screen, screen separately is made of the flame retardant material, in order to prevent the hurt opposite chemical experiment personnel. Therefore, the spacing of the experimental stations at this time should be increased appropriately.

The safe spacing between the test bench and the fume hood is usually not less than 125 cm. For the single-sided test bed against the wall, the above safety spacing requirements should also be met.

If the laboratory is a natural daylighting, then test bench is not parallel to the exterior wall of light inlet window, otherwise, when the researchers turn your back to the window will appear in the experimental stage their own shadow, and, when facing the window, can produce dazzling light.

The height and width of the test bed should be practical to facilitate safe operation. According to the actual situation of our country, the height is 85 cm, usually but if the researchers compare tall, also can take 90 cm, on the other hand, you can take is 80 cm, for some special event study, you will need to draw the corresponding mesa height. The net width of each experiment platform is usually 65 cm. If there are more experimental devices on the surface, it can be widened appropriately, but it is convenient for safe operation. The width of mesa reagent bottle rack can be 20-30 cm. Therefore, the width of the double-sided experiment platform can be 150-160cm, and the width of the single test bed can be 75-85cm.

Test bench can use steel, wood, concrete, etc for material layout, mesa strong smooth, seamless, no leakage, heat resistant, wear resistant, resistant to decay, to have sufficient strength, not easy scratches, but it is not easy to touch the broken glass. Surface material commonly used reinforced concrete, ceramic tile surface of concrete, wood, stainless steel or precast water grinding stone tablets. And the biochemistry laboratory that is engaged in microbiology research, should use seamless white mesa.
