2.7.3 Arrangement of the fume hood The fume hood should be directly adjacent to the pipe well to avoid the exposure of the exhaust air horizontal pipe. The position of the fume hood should take into account the use effect of the fume hood, please refer to the following chapter of laboratory ventilation. When the number of fume hoods is large, it can also form a partition. The configuration number of the fume hood should be determined according to the actual requirements of use. Due to the different types and properties of the test, the requirements are also different. According to the statistics of foreign surveys, for example, comparing the use hours of the fume hood with the total hours of the test work, the use rate of the chemical laboratory is the highest. There are few beauty wins as satisfying as discovering the best hair straightener for your hair. To accomplish this feat, you have to weed through tons of potential matches and, through trial and error, find the flat iron or straightening device best suited for your individual hair texture and time limitations.

The equipment in the basic laboratory includes: experimental benches and water basins (or wash basins); fume hoods and pipeline manholes; workbenches or auxiliary workbenches with reagent racks; research space or record writing in the laboratory needs to be considered Table; instrument table, sky platform, floor medicine cabinet, drug cabinet, glassware cabinet, safety cabinet, emergency shower, eyewash, etc., as well as instruments and equipment placed on the floor.
2.7.2 Arrangement of the experiment table In a naturally lit laboratory, the experiment table should not be parallel to the outer wall of the lighting window, because when the experimenter faces the window with glare, and when facing away from the window, the experimenter's body is on the experiment table There is a shadow on the surface, which is undesirable.
The experimental platform perpendicular to the outer wall should be in accordance with the standard size of the building standard, so that it can be coordinated with the spacing of the flat-top beams, which is conducive to the layout of indoor lighting fixtures.
(1) Island-type central experimental platform Experimental staff can move freely around, which is indeed an ideal layout form in use. The disadvantage is that the traffic area is larger than that of the peninsula-type central experimental platform, and how to introduce the piping on the experimental platform. The current solutions are roughly the following five methods.
1. The floor is provided with a trench and a cover plate, so that the vertical pipeline in the pipeline well or against the wall is introduced into the experimental platform through the trench. However, no matter how well the movable cover is done, there will always be gaps. The chemical liquid on the ground is easy to penetrate, which will cause fluid accumulation in the trench and even corrode the pipeline. It can also be prevented if a layer of closed plastic ground is added to the ground. However, when the piping needs to be repaired or replaced, part of the plastic ground needs to be cut off. If the mending is not tight, it will not be easy for the liquid such as acid and alkali to seep into the trench.
2. The pipeline is directly buried in the floor surface, although there is no such drawback, but when the pipeline needs to be replaced, the ground will be cut, which will affect the normal work of other laboratory rooms, and from the perspective of "flexibility" Defective.
3. The pipeline of the experimental platform passes through the floor and enters the pipeline well along the flat roof of the lower layer. When the pipeline leaks or needs to be repaired, it will inevitably affect the use of the lower laboratory. Therefore, the lower laboratory should not be equipped with high precision instruments. Therefore, due to the high pipeline, it is not very convenient for maintenance.
4. A technical interlayer between the upper and lower floors of the laboratory is an ideal method, but the construction cost is bound to increase.
5. The pipeline hangs directly above the experimental platform along the flat roof. This method is easy to solve technically, but it hinders the cleanliness and beauty of the room. If there is a vertical column near the experimental table, you can set up a tube along the column. A better method.
(2) The peninsula-type central experimental platform There are two types of peninsula-type central experimental platform, one is set by the outer wall, and the other is set by the inner wall. The piping of the peninsula-type experimental platform can be directly introduced from the pipeline maintenance well or directly from the main wall, which can avoid the adverse factors of the island type and save some aisle area. Set the piping near the outer wall and connect it to the riser or pipeline well by the horizontal pipe. The horizontal pipe can be laid along the window sill without passing through the floor slab. .
Based on the above analysis, the island-type central experimental station is more ideal than the peninsula-type central experimental station, but overall, the peninsula-type central experimental station is more advantageous in design. From the practical point of view, the peninsula-type central experimental platform has two working faces and one end is enough to meet the requirements. The peninsula-style central experimental platform has been widely adopted in research laboratories and is considered suitable.

The indoor layout of the basic laboratory can be determined from the length of the test bench occupied by each person after the grouping or organization of the experimenters and the spatial form used are determined, and then the selected The building modulus, the number of fume hoods to be configured, and other equipment give the dimensions of a basic laboratory room.
