Measuring glass is used for measuring the amount of liquid.
modern automatic sprinklers use a glass bulb that is filled with a fluid that boils and expands at a preset temperature. the glass bulb has a small bubble in the fluid. when a fire causes the fluid to boil, it shatters the glass bulb, which is keeping the waterway seal of the sprinkler in place. When the seal is gone, water can flow through the sprinkler orfice, and extinguish the fire. older sprinkler models use a link and lever arrangement, with a link of solder that melts at a preset temperature. The link and levers of the sprinkler mechanically hold the waterway seal of the sprinkler closed. When the link melts, the mechanical seal is gone, and water can flow through the orfice.
Glass beakers are usually used to hold chemical solutions, or a form of liquid.
you use the same glass as you use for winter horticultural, standard, or laminated glass.
the density of the liquid in this glass jar is 5 liter
you use an eyedropper by squeezing the top rubber and putting the tip of the eyedropper into liquid. then, you release the top rubber but still hold on and the liquid will come up and into the glass tube. to dispense liquids, squeeze the rubber until the liquid comes out of the tip of glass.
