Today, I will share with you a device dedicated to collecting and intercepting laboratory waste liquids. Why do you want to introduce this kind of equipment? In fact, this is because many waste liquids in the laboratory are volatile, and these volatilized gases Not only is the taste unacceptable, but long-term inhalation can also cause hidden dangers to human health. For example, some laboratory liquid chromatography will inevitably use toluene as a solvent.
Laboratory waste liquid collection and interception device
We know that toluene is a colorless, clear liquid with a benzene-like smell. Strong refraction. It is miscible with ethanol, ether, acetone, chloroform, carbon disulfide and glacial acetic acid, and very slightly soluble in water. The relative density is 0.866. Freezing point -95℃. The boiling point is 110.6°C. The refractive index is 1.4967. Flash point (closed cup) 4.4℃, low toxicity, LD50 (rat, oral) 5000mg/kg. High concentrations of gas are narcotic. It is irritating. The list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization is preliminary for reference. Toluene is in the list of three carcinogens.
From the above, we can see that the long-term volatilization of laboratory solvents will affect people if they are not properly protected. In response to this situation, many laboratory teachers still use simple bottles to cover them. The plastic bag is dismissed. I don’t know that this degree of protection is difficult to effectively prevent the solvent from evaporating into the air. In response to the current situation, the green laboratory series products launched by Beijing Aowei Instrument Co., Ltd. are safe for laboratory solvent bottles. Sealing and collecting laboratory waste liquid provide green and safe solutions to protect the laboratory environment and care for the health of laboratory personnel.
Solvent safety cap
SE series solvent safety caps can be used for the safe sealing of solvent bottles in liquid chromatography, automatic solid-phase extraction, pressurized solvent extraction instruments and other instruments and equipment. When the instruments and equipment are working, they can efficiently filter dust in the air to prevent solvent contamination and ensure The analysis result is accurate. When the instrument stops working, it can prevent the solvent from volatilizing through the air inlet, and protect the laboratory environment from pollution.
Safety waste cap
Safety waste cap can be used for the collection of waste liquid discharged from the spectrometer, liquid chromatograph, mass spectrometer and pretreatment 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.
Safety Funnels
Safety Funnels is used to collect the waste liquid 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.
