"Labster is cost effective, its easy to use, and you have a better outcome. - Appearance: Disposable pipet, not much information is written on the tube to fill a TC pipet; 4 steps to dispence, then blow out and rinse with receiving fluid You will be introduced to the basics of pipetting as you dive right into the experiments. At the end of this simulation, you will be able to: Select the correct micropipette for its purpose, Quantify the protein content in a sample with a Bradford assay. PDF Use of Micropipettes - Buffalo State College For example, you might carry out three 1 in 10 dilutions instead of one 1 in 1000 dilution. endstream endobj 449 0 obj<>/Size 420/Type/XRef>>stream In the simulation, your challenge is to help a food scientist at LabsterFood Inc. who is hoping to reduce malnutrition. In our virtual labs, we use air-displacement pipettes that aspirate and dispense liquid samples. As you can imagine, it wasnt uncommon to accidentally suck up the solution (often including infectious, toxic or even radioactive substances), contaminate the mouth piece with your fingers, or inhale harmful vapors. d. 1: 50 wells b1&b2, b. Poor guy! Cross), Psychology (David G. Myers; C. Nathan DeWall), Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B. Koehler), Chemistry: The Central Science (Theodore E.
