Scientists require a large amount of equipment in order to successfully plan‚ complete‚ and analyze experiments they conduct. The specific apparatus used varies significantly from lab-to-lab and depends mostly on that particular lab’s planned experiments. However‚ most lab equipment falls into one of a relatively small number of categories. Glassware The bewildering array of available glassware includes several specialized pieces of equipment that scientists use to measure liquids and crystallize

Over 100 million animals are burned‚ crippled‚ poisoned and abused in U.S. labs every year. 92 percent of experimental drugs that are safe and effective in animals fail in human clinical trials because they are too dangerous or don’t work. Labs that use mice‚ rats‚ birds‚ reptiles and amphibians are exempted from the minimal protections under the Animal Welfare Act (AWA). Up to 90 percent of animals used in U.S. labs aren’t counted in the official statistics of animals tested. The

Abstract- Expirement 1: Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a
