First, there are a lot of sundries. There are glassware, bottles and cans piecemeal; glass conduits vary in length, fragile and fragile. Instruments and supplies range from ovens and scales to nails and wires. There are other things that look insignificant but are not necessary for doing some experiments, such as glass, chips, odd pieces of cloth, cotton, cotton thread, wool, mud, sand, stone, wooden blocks, wooden strips, etc.

Second, there are many medicines. Toxic, harmful, flammable, explosive, volatile, liquid, solid, organic, inorganic, forest total hundreds of pharmaceutical reagents. And the performance is different, some can not be exposed to the air, encounter the air on fire, to be preserved in water. Others can't touch water. When they meet water, they make a fire. Kerosene should be kept in the kerosene.

The third feature is the use of more water. Chemical reactions are mostly carried out in solution, and water is indispensable. The preparation of most pharmaceutical reagents also needs water, and a large number of glass instruments can not be cleaned without water. Based on the above "three-plus" characteristics, the chemical laboratories are managed by compartments and classifications.

Instrument room: This room is equipped with various chemical testing instruments besides pharmaceuticals: various kinds of balance, acidity meter, centrifuge and other precision instruments, as well as test tube, beaker, measuring cylinder, dropper and other glass instruments.

Drug Depot: The most terrible thing in Chemical Depot is that the drugs are piled up in disorder and dilapidated. Drugs piled up in disorder, drugs expired and labels dilapidated are all potential safety hazards. Drug reagents should be classified and stored in appropriate places according to their different properties. The separation of inorganic and organic, oxidant and reductant, toxic and harmful, flammable and explosive. The cabinets also take appropriate safety measures according to the nature of different drugs. At the same time, drug use registration should be done well.

I. Requirements for display and storage

The general principles of display and storage of instruments are: scientific, standard, safe, reasonable, beautiful and convenient.

1. Meeting the Scientific Requirements

Instruments should be displayed and stored scientifically, not in disorder. For example, the storage of magnets should prevent vibration and demagnetization, so as to close the magnetic circuit, the north and south poles of bar magnets should be two opposite poles, corresponding to staggered overlapping, so that the opposite poles can be matched; the hoof magnets should be attracted by opposite poles, and a single hoof magnets should be added an armature between them, placed on the U-shaped mouth to form a clumped magnetic circuit. The small magnetic needle should be stationary in the direction of the earth's magnetic field, and the external magnetic field should influence it to prevent the magnetic field from weakening. Long-term approximation of the magnetic poles of the same name will affect the polarity. Several small magnetic needles should be connected north and South together.

2. Compliance with management requirements

Display and storage is an important basis and content of scientific management. It is necessary to write cabinets according to classification number, classification number, location by number, stratification in cabinets, fixed points on cabinets, labels on each piece, and catalogues on each cabinet, so as to keep them in order vertically and horizontally, vertically up and down. The cabinets where the instruments are placed should be numbered according to the unified disciplines, and the positioning labels should be posted on the cabinets.

柜门定位标签要注明柜内仪器的编号、名称、规格、数量,用碳素墨水书写,张贴于柜门上方或右侧,张贴标签要整齐美观,便于查找。

Instruments and chemicals should be stored separately. Drugs are mostly corrosive to metal parts. Gases produced by drugs are harmful to other instruments. It is best to store them separately and keep them. Drugs are few and need not be stored separately, but effective measures should be taken to isolate them, actively create conditions and keep them separately. Drugs should be kept in dry, cool, ventilated and light-proof places, solid reagents in wide-mouth bottles; liquid reagents in fine-mouth bottles; light-prone reagents in brown bottles, alkali bottles with rubber stoppers; acid bottles should not use rubber stoppers or cork stoppers, generally with grinding glass bottles.

3. Meeting the Requirements for Use

The display and storage of instruments should be easy to access, and can be guaranteed in the shortest time, so as to avoid random searching everywhere and wasting time. Instruments should be stored in a fixed area and kept in a relatively stable position. It is a common method to paste numbers or draw patterns of instruments and tools in rotating instruments and tools. When the instruments and tools are not in place (such as not returned from loan), they can be found immediately, which is more convenient to check.

4. Meet the aesthetic requirements

The display and storage of instruments should be conducive to strengthening management and observation. In the past, most of the instrument cabinets were opaque. Now, transparent cabinets or transparent cabinets on the upper part are used to change the closed management into open management. Therefore, the display and storage of instruments should be neat and standardized, orderly, beautiful and generous, and attention should be paid to the artistry of the display. But the display of instruments should not be the same as the display of commodities. Don't be colorful and dazzling.

5. Compliance with Safety Requirements

The display and storage of instruments should also do a good job of safety precautions, eliminate the hidden dangers of accidents and eliminate all accidents. Precious instruments and flammable, explosive and toxic drugs should be kept under special measures.

II. General Principles of Display and Storage

1. All instruments should be put in the cabinet. Except for those too large to fit in the cabinet, they should be put in the cabinet as far as possible. If the cabinet can't be put in, it can be placed on the top of the cabinet or on the shelf, with dust-proof cover (such as transparent plastic bags), and can't be put on the ground. Instruments are generally stored in large parts in the next, small pieces in the top; short pieces, small pieces in the front, high pieces, large pieces in the back; heavy parts in the next, light parts in the top; low-grade instruments in the next, high-grade instruments in the top.

2. Instruments should generally be lowered and laid flat. Many instruments, such as scales and microscopes, cannot be reversed.
