In order to carry out reactions in a controlled manner, it is essential to know the quantities of substances required and to weigh the corresponding substances accurately. A weighing glass can be used for weighing. The associated lid allows the weighing pan to be closed and thus prevents, for example, turbulence of the weighed-in solids during transport. Since even the smallest contamination of the weighing glass can have an effect on the weighing inheritance, the glass in the area of the ground joint and the lid knob are so pronounced that they can be grasped and moved with forceps or tweezers.
