With the development of the green process, the laboratory environment is also highly valued today. In order to solve the pollution problem caused by the volatilization of laboratory waste liquid, many teachers began to look for a laboratory waste liquid intelligent environmental protection collection bucket, a lot of experimental equipment and work Waste liquid will inevitably be generated in the process. Just like liquid chromatography, toluene will be used as an experimental solvent in a certain experimental environment. The volatilization of these toluene waste liquids is the main source of laboratory environmental pollution.

Intelligent environmental protection collection barrel for laboratory waste liquid

Generally speaking, there are various waste liquids in the laboratory. The following is a small list to help everyone have a clear understanding:

A·Organic Waste Liquid

(1) Greases: waste oil (grease) produced by school laboratories or factories, such as lamp oil, light oil,

Turpentine oil, paint, heavy oil, creosote oil, spindle oil, insulating oil (grease) (excluding PCBs), lubricating oil, cutting oil, cooling oil, animal and vegetable oil (grease), etc.

(2) Halogen-containing organic solvents: waste solvents generated by school laboratories or factories, which should be dissolved

"Contains aliphatic halogen compounds, such as chloroform, methyl chloride, difluoromethane, picochlorocarbon, methyl iodide, etc., or aromatic halogen compounds, such as chlorobenzene, benzyl chloride, etc.

(3) Halogen-free organic solvents: waste solvents produced by school laboratories or factories, which do not contain aliphatic halogen compounds or aromatic halogen compounds.

B·Inorganic waste liquid

(1) Waste liquid containing heavy metals: Waste liquid produced by school laboratories or factories. The waste liquid contains any kind of heavy metals (such as iron, cobalt, copper, manganese, cadmium, lead, gallium, chromium, titanium, Nagisa , Tin, aluminum, magnesium, nickel, zinc, silver, etc.).

(2) Cyanide-containing waste liquid: waste liquid produced by school laboratories or factories, which contains free cyanide waste liquid.

(need to be stored at pH 10.5 or higher) or contain cyanide compounds or cyanocyanide compounds.

(3) Waste liquid containing mercury: Waste liquid produced by school laboratories or factories, which contains mercury.

(4) Fluorine-containing waste liquid: Waste liquid produced by school laboratories or factories, which contains fluoric acid or fluorine compounds.

(5) Acid and alkaline waste liquid: waste liquid produced in school laboratories or factories, which contains acid or alkali.

(6) Waste liquid containing hexavalent chromium: waste liquid produced by school laboratories or factories, which contains hexavalent chromium compounds.

In order to avoid the impact of laboratory waste liquid volatilization on the health of laboratory staff, the green laboratory series products launched by Beijing Aowei Instrument Co., Ltd. provide green and safe solutions for the safe sealing of laboratory solvent bottles and laboratory waste liquid collection. The solution is to protect the laboratory environment and care for the health of laboratory personnel. This is a very smart and environmentally friendly laboratory waste collection barrel.

Among them, the SE series of solvent safety bottle caps can be used for the safe sealing of solvent bottles in liquid chromatography, automatic solid phase extraction, pressurized solvent extraction instruments and other equipment, and can efficiently filter dust in the air when the equipment is working to prevent solvent pollution , To ensure the accuracy of analysis results, when the instrument stops working, it can prevent the solvent from volatilizing through the air inlet to protect the laboratory environment from pollution.

Intubation type waste liquid collection device, which can be used to collect waste liquid discharged from spectrometer, liquid chromatograph, mass spectrometer and pre-processing equipment in the laboratory. The exhaust gas filter can efficiently adsorb the volatilized harmful gas and protect the laboratory environment , Care for the health of experimenters. Liquid level alarm prevents liquid overflow. Various types of secondary containers prevent secondary pollution and meet regulatory requirements.

Funnel type waste liquid collection device is used for waste liquid collection during the experiment. The exhaust gas filter efficiently adsorbs harmful gases to protect the health of the experimenter. Liquid level alarm prevents liquid overflow. Various types of secondary containers prevent secondary pollution and meet regulatory requirements.
