Laboratory room configuration should be determined according to specific circumstances. More laboratory rooms are possible for large feed enterprises and less for small and medium enterprises, but instruments should be placed based on the nature of work, usage, mutual influence, put the equipment be arranged, in order to facilitate management. The large laboratory can have a physical examination room(for physical examination), laboratory (for routine chemical examination of samples), scale room (for sample weighing), precision instrument room (placed with precision instrument such as colorimeter, pH meter, fluorescence spectrophotometer, etc.), electric heating room (placed with muffle furnace, oven, electric heating plate, constant temperature and humidity box) and sample storage room. Laboratory in small and medium sized enterprises cannot be subdivided due to limited area, but it should at least have an examination room and instrument room.
The laboratory floor should be placed with polished tiles, terrazzo tiles or acid-proof ceramic tiles or use peroxide vinyl paint. Walls can brush paint to reduce the absorption of poison and dust. The height of platform top is 850mm and width 750mm. Scale, acidometer, chromometer and fluorophotometer can be placed on the platform.
Experimental platform can be placed in the middle of the examination room with commonly used reagents on the platform. Laboratory water pipe/faucet and sewage pipeline can be arranged so as to get condensate water during crude fat test. Washing basin should be prepared on both sides of the experimental platform. Sockets can be installed on the reagent shelf to have a relatively closer power supply.
Ventilation cabinet and electric heating table can be installed on one side of the examination room. The size of the ventilation cabinet can be determined according to the size of room, size 1200/1500/1800mm, depth 800mm and height 2350mm. The other side can be arranged according to the rest area of the examination room. If the area is too small, medicine cabinets (keeping commonly used non-hazardous medicine), equipment cabinets and sample cabinets can be placed; if the area is large, instrument, commonly used non-precision instruments such as electric stove and water bath can be placed.
