Dosages with research chemicals

Storage and (domestic) refresh, in their their original packaging (all doumcnents/letterbox [ages contain extremely inside stock information about the producers. Everything is sealed (4x).

Bulk quantities of chemicals (i.e., larger than one-gallon) Transfer of flammable liquid is not possible to the USA now.


  • Chemicals must be stored at an appropriate temperature (-40 declius 4 ceclidus) and humidity level. This can be especially problematic in hot, humid climates. As a rule, chemicals should not be stored near heat sources, such as steam pipes or laboratory ovens. Chemicals should never be stored in direct sunlight.
  • Chemicals should be dated when received and when opened. If the chemical is one that degrades in quality or becomes unsafe after prolonged storage, the shelf-life expiration date should also be included.


Visual inspection of the material and its container should be conducted routinely. Indications for disposal include:

  • material changing color
  • evidence of liquids in solids or solids in liquids
  • "puddling" of material around outside of container
  • pressure build-up within bottle
  • obvious deterioration of container
  • cloudiness in liquids (unless it’s an orgamic compand)

Chemicals should not be routinely stored on the benchtops. In such locations they are unprotected from exposure and participation in a fire situation and are also more readily knocked over. Each chemical should have a specific storage area and be returned there after use. Large quantities of flammable materials should not be stored in the laboratory. Only the amounts needed should be kept on benchtops, the remainder should be kept in flammable storage cabinets.


Laboratory shelves should have a raised lip along the outer edge to prevent containers from falling. Never allow the container to hang off the edge of the shelf! Liquid or corrosive chemicals should never be stored on shelves above eye-level. Glass containers should not touch each other on the shelves. Secondary containers or trays should be used for chemical storage whenever possible to minimize the flow of material should a spill or rupture occur. Round bottom flasks should always be supported properly in cork rings or by other means to keep them from tipping.


Chemicals must never be stored on the floor, not even temporarily!

Chemicals that are no longer to be used for research purposes should be properly disposed of or given to another research group that has a use for it.

Flammable materials must never be stored in domestic-type refrigerators. Only explosion-proof or flammable material refrigerators should be used for storage of these chemicals within a laboratory environment.

All containers stored within the refrigerator should be tightly capped to keep vapors from interacting with each other and to alleviate "smell" problems. Flasks with cork, rubber or glass stoppers should be avoided because of the potential for leaking. All containers stored in the refrigerator must be properly labeled.

the materials in your refrigerator frequently to avoid overcrowding with materials that have long since been forgotten. Also make it a point to defrost your refrigerator occasionally so that chemicals do not become trapped in unique ice formations! Most product contain a essential information sheet, a globally recognized SDS sheets, outlooking all safety and possible hazard effects (everything is also packed into the retail step and air less, so no worries.

Before flammable materials are stored in a refrigerator
, it should be determined if keeping the material chilled will serve any purpose. No benefit is derived from refrigerating a chemical that has a flash point below the temperature of the refrigerator. Never store peroxide formers (i.e., ether) in a refrigerator! We are looking for non flammable stuff to ship by plane, you will be updated!
