can it cause any injury while working?
A number of common pipetting techniques have been identified as potentially hazardous due to bio-mechanical stress factors.
Pipette
During repetitive tasks such as pipetting, maintaining body positions that provide a maximum of strength with the least amount of muscular stress is important to minimize the risk of injury. A number of common pipetting techniques have been identified as potentially hazardous due to biomechanical stress factors. 
name two articles that can be made from glass Window panes and tableware. how can you describe its microscopic structure? Although the atomic-scale structure of it shares characteristics of the structure of a supercooled liquid, glass exhibits all the mechanical properties of a solid. As in other amorphous solids, its atomic structure lacks the long-range periodicity observed in crystalline solids. Due to chemical bonding constraints, they do possess a high degree of short-range order with respect to local atomic polyhedra. how it is formed? For melt quenching, if the cooling is sufficiently rapid then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at T. The tendency for a material to form a glass while quenched is called glass-forming ability. what is process you just mentioned? “Crystallization” is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. what are methods involve in this process? Crystal formation can be achieved by various methods, such as: cooling, evaporation, addition of a second solvent to reduce the solubility of the solute, solvent layering, sublimation, changing the cation or anion, as well as other methods. what is its thermodynamics view? The molecules within a pure, "perfect crystal", when heated by an external source, will become liquid. This occurs at a sharply defined temperature. As it liquifies, the complicated architecture of the crystal collapses. Melting occurs because the entropy gain in the system by spatial randomization of the molecules has overcome the enthalpy loss due to breaking the crystal packing forces. what are the laboratory applications of the above mentioned solid? Flasks, petri dishes, test tubes, pipettes, graduated cylinders, glass lined metallic containers, fractionation columns, glass pipes, Schlenk lines, gauges, and thermometers are some of them. what is the fourth one? “Pipette" is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser. are there any types of this tool? Volumetric pipettes is one type.

Pipette [SEP] Posture and Injuries
Proper pipetting posture is the most important element in establishing good ergonomic work practices. During repetitive tasks such as pipetting, maintaining body positions that provide a maximum of strength with the least amount of muscular stress is important to minimize the risk of injury. A number of common pipetting techniques have been identified as potentially hazardous due to biomechanical stress factors. Recommendations for corrective pipetting actions, made by various US governmental agencies and ergonomics experts, are presented below.
