procedure, a funnel with a rubber stopper, a trapper flask, and a small piece of filter paper is important to have. There is also a need for vacuum hoses in the filtration process as well. The student will also need a hotplate. The lab will provide all the necessary pipes needed to setup a vacuum and also the air current needed later on in the collection phase. Each lab will have different types of equipment, and it is the students responsibility to understand and learn how to work each tool.
             For any experiment to have the proper results, cleaning and sterilization is critical part of preparation. The best way to have the glassware cleaned is to steam clean the many pieces in a autoclave or a dishwasher. This may be done in advance by the instructor or the students. It is also good practice to clean the equipment by hand, even after it has come out of a machine cleaner. The funnel and the filter paper must also be free of any impurities so that it will not reflect in the result. Because the purification process is so important, there has to be a high standard of cleanliness for all the tools that the student will use.
             *It is extremely important that the student make sure all the pieces are dry as well or the weight of excess water will show up in the results. Thus exaggerating the final calculations*
             Above all else, it is important to take all the proper methods to be safe in the laboratory. All Students must wear safety goggles at all time in the lab. It would also be a good idea
