In the lab

In a laboratory, various shapes and objects such as cubes, prisms, and cylinders are commonly encountered alongside essential lab equipment like burettes, beakers, and pipettes. Safety is paramount, and adherence to guidelines like wearing lab coats and using gloves is crucial, reinforced by symbols indicating radiation, biohazards, and electrical risks.
