Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Electric machines and power electronics experiments involve electrical currents, voltages, power, and energy quantities that should be handled with extreme diligence and care. These may include three-phase AC voltage (208 V, 230 V, or 480 V), up to 250 V DC voltages, and currents that can reach 10 A. Electrocution occurs when an electrical path is established through the body with very low currents...

Source: Robert M. Rioux, Ajay Sathe & Zhifeng Chen, Pennsylvania State University, University Park, PA Vacuum is required for a number of laboratory procedures. This is most routinely achieved in the laboratory by the use of vacuum pumps. In addition to working at low pressures, vacuum pumps can also be used to enable rapid changing of the atmospheres in a reactor or flask by evacuation and backfilling.

Source: Laboratory of Dr. Dana Lashley - College of William and Mary Demonstrated by: Timothy Beck and Lucas Arney Many reactions in organic chemistry are moisture-sensitive and must be carried out under careful exclusion of water. In these cases the reagents have a high affinity to react with water from the atmosphere and if left exposed the desired reaction will not take place or give poor yields, because the reactants are chemically altered. In order to prevent undesired reactions with H2O...
FAQs
Microscopes use lenses to magnify cells and microorganisms, allowing investigators to examine biological material at a scale that cannot be assessed directly. In biology, this capability supports microscopy-based studies and helps connect observed cells or microorganisms with broader questions about cellular processes and biological systems.
Pipettes deliver measured liquid volumes, so their accuracy directly affects how consistently biological samples, reagents, or reactions are handled. Reliable volume delivery improves reproducibility between experimental conditions and helps researchers interpret differences as biological effects rather than consequences of inconsistent liquid quantities.
A centrifuge separates components according to density by spinning a biological material. Components respond differently during this process, allowing researchers to obtain separated fractions for subsequent analysis. This physical principle makes centrifugation useful in molecular biology and biochemical analysis, where distinct sample components may need to be examined independently.
Incubators maintain suitable temperature conditions for biological growth or reactions. Stable temperature control helps preserve the conditions required for the intended process, supporting reproducible outcomes in applications such as cell culture, microbiology, and biochemical work. The appropriate setting depends on the growth or reaction being investigated.
Selection should match the instrument to the task, such as magnifying cells, delivering a defined liquid volume, separating components, or maintaining temperature. Researchers should also calibrate equipment before use and apply it under controlled conditions. These practices improve measurement quality, experimental consistency, and confidence in the resulting biological observations.
A biological workflow may combine pipettes for measured liquid handling, centrifuges for density-based separation, microscopes for examining cells or microorganisms, and incubators for maintaining growth or reaction conditions. Using these instruments together supports connected stages of cell culture, microscopy, molecular biology, microbiology, and biochemical analysis.
Laboratory equipment supports investigations ranging from cell culture and microscopy to molecular biology, microbiology, and biochemical analysis. These applications allow researchers to study cellular processes, disease mechanisms, and biological systems under controlled conditions. Properly selected and calibrated instruments strengthen the precision and reproducibility of findings across these research areas.
