What to collect the waste liquid after the laboratory is a problem that many laboratory personnel are concerned about. With the advent of the green and healthy era, the proper collection of laboratory waste liquid will become the future trend. How to prevent the volatilization of mobile phase? Safer collection of hazardous waste liquids in the laboratory is a problem that everyone is actively looking for solutions. Let us look at the recommendations for the collection and disposal of waste liquids in the laboratory.

What to collect the waste liquid after the laboratory is a problem that many laboratory personnel are concerned about. With the advent of the green and healthy era, the proper collection of laboratory waste liquid will become the future trend. How to prevent the volatilization of mobile phase? Safer collection of hazardous waste liquids in the laboratory is a problem that everyone is actively looking for solutions. Let us look at the recommendations for the collection and disposal of waste liquids in the laboratory.

Storage of toxic and hazardous wastes and waste reagents. Waste chemical reagents in the laboratory and toxic and hazardous wastes and waste generated in experiments are strictly prohibited to be dumped into the drain or thrown away with the garbage. Do not put the waste chemical reagents in the corridor, balcony, courtyard, etc. In public, offenders will be strictly investigated and punished. Toxic and hazardous waste liquids and waste chemical reagents should be placed in accordance with the following regulations:

  1. The solid should generally be stored in the (original) old reagent bottle, marked as a waste reagent, and temporarily stored in the reagent cabinet.


2. For liquids, the School of Chemistry and Chemical Engineering uniformly purchases plastic buckets (divided into three categories and printed with signs) and distributed them to chemical laboratories to collect halogen-containing organics, general organics, and inorganic wastes. The waste liquid collection barrel should be tightly closed at all times and placed in a cooler place in the laboratory. The main toxic and hazardous components entering the waste liquid collection barrel must be registered on the "Chemical Waste Record Sheet", and the full name or chemical formula of the toxic and hazardous components must be written. Abbreviations or abbreviations are not allowed. After the bucket is full, paste the record sheet on the corresponding bucket.


3. Hazardous waste liquid does not include waste liquid containing highly toxic reagents. The highly toxic waste liquid cannot be directly put into the above-mentioned three types of collection barrels. For specific treatment methods, please refer to our hospital "Supplementary Regulations on the Management of Highly Toxic Reagents". 2. Disposal of toxic and hazardous waste liquids and waste reagents 1. Recycling and processing of waste liquids After the waste liquid barrels in the laboratory are full, the corresponding experimental technicians notify the experimental center, and the experimental center will arrange for personnel to collect and transport the waste liquid. Send empty bucket. The recovered waste liquid is temporarily stored in a centralized manner, and depending on the inventory, contact the competent department and the chemical hazardous material processing plant in a timely manner for disposal. Relevant personnel of the experimental center are responsible for the organization of collection, transportation and consumption, and the coordination and cooperation of the hospital office.


4. Recycling and disposal of waste reagents When the laboratory prepares to dispose of waste chemical reagents (solid, liquid), it can fill in the "Registration Form of Waste Reagents" and submit it to the laboratory center, which will be responsible for contact processing or disposal. The laboratory center notified the laboratory to put the waste reagents in the designated location one day before the disposal.


5. Recycling and treatment of waste highly toxic reagents When the laboratory prepares to dispose of waste highly toxic chemical reagents (solid, liquid), it can fill in the "Registration Form of Waste Highly Toxic Reagents" and submit it to the laboratory center. The laboratory center is responsible for contacting the competent authority For disposal or disposal, the reagent library informs the laboratory to send the waste highly toxic reagents to the experimental center before disposal.


The green laboratory series products of Beijing Aowei Instruments are specifically designed to solve this problem. They are mainly divided into two categories: solvent safety bottle caps and intubation/funnel waste collection devices. Among them, solvent safety bottle caps It is mainly used to efficiently filter the dust in the air, prevent the mobile phase from polluting, and ensure the accuracy of the analysis result; when the chromatographic instrument stops working, prevent the mobile phase from volatilizing through the air inlet to protect the laboratory environment from pollution.


The intubation type/funnel type waste liquid collection device is a kind of waste liquid collection used in the experiment process. The exhaust gas filter efficiently adsorbs harmful gases to protect the health of the experimenter. Rechargeable liquid level alarm to prevent liquid overflow. Various types of secondary containers prevent secondary pollution and meet the requirements of laws and regulations for waste collection devices. In this era of great health, the laboratory environment must also be paid more attention to to care for the laboratory environment and protect the health of laboratory personnel.
