1, site selection and scale M
Laboratory should be built away from dust, noise, odor emitting gases and other locations, the power supply voltage should be relatively stable location.
According to the size of the enterprise and the type of products, should be built with different requirements of the laboratory. However, the minimum floor area: physical and chemical testing room can not be less than 30 square meters; microbiological testing room (sterile room) can not be less than 8 square meters. This will help the rational placement of instruments and equipment, easy to operate, easy sample circulation and air circulation.
The room should have adequate lighting conditions.
The room must be equipped with dry powder or carbon dioxide fire extinguishers, in order to prepare for electrical appliances or chemical combustion fire.
All electrical plugs should have a solid ground device to prevent the equipment charged, resulting in electrocution of the operator. Conditions should also be laid on the ground insulation board. Secondly, there should be water and sewage facilities, fume cupboards (in the fume cupboard for the occurrence of harmful gases out of the analysis of the operation).
2, indoor layout
Separate from static instruments: precision instruments (such as photometers, balances, colorimeters, acid meters, chromatographs, etc.) should have to vibrate with the instrument (such as shock absorbers, powder sieves, centrifuges, stirrers, etc.).
Separation of room temperature and heat source equipment: heat source instruments (such as electric distilled water, constant temperature drying oven, high temperature resistance furnace, constant temperature incubator, water bath, electric furnace, etc.) must be separated from all other equipment, otherwise it will affect the normal use of other equipment, serious thermal vapor corrosion of other equipment, affecting its service life.
Chemical analysis of the table and heat source equipment separately: chemical analysis of the table should be put as little as possible on the flammable and corrosive reagents. The use of electric furnaces or alcohol lamps heating should be insisted on someone to watch and monitor.
Chemical analysis table should be placed away from the heat source equipment.
3, sensory testing precautions
For sensory testing of food, do not use beakers or measuring cups to taste. Must use tableware tasting. To avoid indirect poisoning or personal health damage.
