Storage Bin

Storage bin used in laboratory

What is storage bin?

storage-baskets
Storage bin, also known as storage basket. It is made of a variety of materials, and these materials usually including plastic, fabric, paper, metal, wood, etc.

Plastic storage bins usually have a lid seal. Storage boxes with lids have the characteristics of the labor-saving movement, oil resistance, non-toxic and tasteless, easy to clean, neatly stacked, easy to manage, high bearing strength, can be stacked, space-saving, lightweight, etc.

Storage bins with lids can be used for transportation, refrigeration, hardware, supermarkets, laboratories, storage (vegetables, fruits), household, turnover, organization (documents, clothes, toys), etc.

Proper placement, storage, container selection, and other considerations for laboratory chemicals

When chemicals are stored, they are often caked or frozen due to changes in temperature and humidity in the surrounding environment, which causes deterioration and affects their quality, thus making the cost higher. Therefore, according to the different physical and chemical properties of reagents, corresponding temperature and humidity control measures must be taken to preserve them properly.

Some reagents are easy to absorb moisture and deliquesce or hydrolyze; some are easy to react with oxygen, carbon dioxide, or other gases diffused in the air, and some reagents will deteriorate under the influence of light and ambient temperature.

Storage of chemical substances

a. Compounds with a low boiling point, drugs that need to be preserved at low temperature shall be put into the required environment (low-temperature refrigerator) as required.

b. Drugs are kept away from light and the reagents they are prepared for shall be kept in brown containers (bottles) or wrapped in dark paper as required.

c. Drugs are always placed in the medicine cabinet and shall not be placed mixed with the prepared solution.

d. Liquid drugs are placed in short cabinets. Solid drugs are placed separately from liquid drugs.

e. Acids and bases should not be mixed, oxidizers and reducing agents should not be mixed, and reagents that will react violently if mixed should not be mixed to prevent accidents that may be caused by dumping, breaking, and other accidental reasons.

f. For some drugs stored in a room temperature environment, you must pay attention to moisture, otherwise, solid caking will occur.

g. The reagent bottles are usually produced from ordinary glass, which is very thick and easy to blow up if the temperature changes too drastically. So the temperature of the storage room should be kept at about 15℃, and it should be kept warm in winter.

h. Both sulfuric acid and hydrochloric acid are not easy to store. Although they are both acids, sulfuric acid should be kept separate from formic acid, acetic acid, and hydrochloric acid.

i. Formic acid, acetic acid, and hydrochloric acid are highly volatile, so they should be well ventilated and the acid mist should be discharged in time.

j. Sulfuric acid has strong oxidation and strong dehydration, so it should be placed separately.

Nine common chemicals stored in environmental conditions

Different chemicals have different hazardous characteristics, so they should be treated separately in terms of temperature and humidity requirements to favor storage safety and quality assurance.

a. Explosive materials should be stored in the warehouse temperature below 30 ℃, and the relative humidity should be maintained at 75-80 percent.

b. Generally, the oxidizer should be controlled below 30℃. For some oxidants containing crystalline water such as nitrates due to heat melting and loss of crystalline state caused by dampness, the temperature of the warehouse should not exceed 28 ℃, to be kept in the insulation warehouse. Relative humidity should be maintained at less than 75%.

c. For compressed and liquefied gases, the warehouse temperature should not exceed 32℃ and the relative humidity should be controlled below 80% to prevent the cylinders from rusting.

d. For spontaneous combustion items, the warehouse temperature should be about 28-30 ℃, and the relative humidity should be maintained at 80% or less. For storage of the yellow phosphorus depot, the minimum temperature of the winter depot cannot be lower than 3 ℃.

e. For moisture-proof items, the temperature of the storage room should be around 30℃. Relative humidity should generally be below 75 ℃, special attention should be paid to the measures to prevent moisture.

f. Strict control of the storage of flammable liquids in the library temperature is necessary to prevent the library temperature is too high, especially according to the boiling point of the liquid and the flash point of the high and low to control the temperature.

g. If the humidity of the warehouse is too high or too much, it will affect the safe storage of flammable solids. Such as nitrocellulose storage needs to contain 30% of the wetting agent ethanol, and the temperature in the library should be controlled below 30 ℃. Camphor, refined tea, and other relative humidity should be below 80%. Storage of secondary flammable solids in the warehouse, the temperature should not exceed 32 ℃.

h. The temperature of the warehouse for storing toxic products should not exceed 32℃, and the relative humidity should be controlled at less than 80%. For cyanide, the warehouse should be kept dry, because cyanide in contact with moist air can produce highly toxic hydrogen cyanide gas.

i. Corrosive goods. Such items have more varieties and different properties, so the temperature and humidity must be controlled according to their nature.

Protection of chemical substances in laboratories

A. Anti-volatilization

a. Oil seal. Ammonia, concentrated hydrochloric acid, concentrated nitric acid and other volatile inorganic liquids, 10-20 drops of mineral oil on the liquid surface can prevent volatilization (vegetable oil cannot be used).

b. Water seal. Carbon disulfide can be stored for a long time by adding 5mL of water to it. Mercury with water can prevent mercury vapor into the air. Put some sulfur powder next to the mercury, and once lost, scatter the sulfur powder so that the mercury remains eliminated in the chemical reaction.

c. Wax seal. Ether, ethanol, formic acid, and other lighter than water or soluble volatile liquids, as well as naphthalene, iodine, and other volatile solids, tight bottle stopper, the mouth of the bottle wax coating. Bromine in addition to the original bottle wax seal, the original bottle should be placed in a plastic cylinder with activated carbon, the mouth of the cylinder wax seal.

B. Moisture-proof

a. Bleaching powder and sodium peroxide should be waxed and sealed to prevent water absorption and decomposition or water absorption and explosion. Sodium hydroxide is easy to absorb water dampness, and should be wax seal; ammonium nitrate, sodium sulfate is easy to absorb water knot shape, cannot pour out, and even lead to the rupture of the reagent bottle, should also be tightly wax seal.

b. Calcium carbonate, anhydrous copper sulfate, phosphorus pentoxide, and silica gel very easy to absorb water deterioration, and red phosphorus is easy to be oxidized, and then absorbs water to generate metaphosphoric acid, each of the above substances should be stored in a desiccator.

c. Although concentrated sulfuric acid should be airtight to prevent water absorption, it is very commonly used and should be placed in a mill-mouth bottle. The grinding mouth bottle stopper should be original, do not transfer.

d. In the basement of special drugs, it is necessary to place block ash in the lower layer, slaked lime in the middle layer, and double tar paper in the upper layer before storing the drugs.

C. Anti-deterioration

a. Anti-oxidation. Sodium sulfite, ferrous sulfate, and sodium thiosulfate are easy to be oxidized, the bottle mouth should be waxed.

b. Anti-carbonation. Sodium silicate, sodium peroxide, and caustic soda are easy to absorb carbon dioxide and should be waxed.

c. Anti-weathering. Crystal sodium carbonate, and crystal copper sulfate should be waxed and stored in the basement.

d. Anti-decomposition. Ammonium bicarbonate and concentrated nitric acid are easily decomposed by heat. After waxing, store it in the basement.

e. Activated carbon can adsorb a variety of gases and deteriorate, so it should be placed in the desiccator.

f. Yellow phosphorus is prone to spontaneous combustion in the presence of air, always save water, every 15 days to check the water once. When checking the water, add water in the phosphorus reagent bottle, place in the water with water lees, on the addition bellows closed.

g. Potassium and sodium are preserved in kerosene.

h. A few drops of dilute sulfuric acid in ferrous sulfate solution, add an excess of fine iron powder, and wax seal.

i. Glucose solution is easy to mold, slightly add a few drops of formaldehyde can be preserved.

j. Formaldehyde is easy to polymerize, and should be opened immediately after the bottle with a small amount of methanol; acetaldehyde then adds ethanol.
