clean pipette‚ add lactase solution to each tube‚ until the level of mixture in each tube comes up to the 1.0 line of the tube. Place both tubes in the 40 degrees celsius water bath and incubate them for 10 minutes. The other thing needed is glucose strips. After the tubes have been incubated for 10 minutes‚ place a glucose strip in each tube for one second. Let it sit for thirty seconds‚ then compare to the chart provided. For unit 7.4 the experiment called for two microfuge tubes. One labeled "control"

hour and the flask was cooled in a beaker in the water of room temperature. The solid was formed in the mixture and the flask was shaken until it dissolved. The flash was rinsed with 15 mL dichloromethane and it was added to the separating funnel. 10 mL of water was added to the funnel and shaken to mix the layers. The lower organic phase was drained into the Erlenmeyer flask and the aqueous phase out of the funnel. After that‚ the organic layer was returned to the separating funnel and washed

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water
