An explosion can occur due to the common use of liquid nitrogen in the cold trap, used to protect the vacuum pump from solvents. If a reasonable amount of air is allowed to enter the Schlenk line, liquid oxygen can condense into the cold trap as a pale blue liquid.
Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.
Erlenmeyer flasks (introduced in 1861 by German chemist Emil Erlenmeyer (1825–1909)) are shaped like a cone, usually completed by the ground joint; the conical flasks are very popular because of their low price (they are easy to manufacture) and portability; Volumetric flask is used for preparing liquids with volumes of high precision. It is ...
