A Bunsen burner can be very useful if is as used properly. There are many different types of Bunsen burners but they all use a mixture of gas and oxygen to make a flame that could be used in a laboratory. To use a Bunsen burner‚ there are several critical steps. But before one starts any experiment‚ one should always read through the experiment procedures and make sure that one clearly understands all steps of the experiment. First‚ one must make sure the main gas is on. It is very important

help structure these decisions‚ but division leaders did not want to see their projects cut‚ so they criticized the list and delayed action‚ resulting in no development or implementation of a strategy. Kirkham Instruments was a manufacturer of laboratory analytical equipment with turnover of £450M in 1995. The company was organized into four divisions: the Mass Spectrometer Division; the Chromatography Division‚ a manufacturer of gas and liquid chromatographs; the Optical Equipment Division which

Introduction to Microscale Laboratory Niki Gharavi *‚ Minh Nguyen San Jose City College ABSTRACT: The objective of the experiment was to be introduced to working with the lab equipment‚ specifically heating and measuring‚ and to be able to create some of the apparatus that future experiments will require. Heating methods used were an aluminum block‚ a sand bath‚ and a water bath. The aluminum block heated most quickly while the others were more stable. Regarding the measurement of water‚ the less
