Pipette

materials for this lab are: stands for oakridge tube and high-titer lysate conical tube, 10 milliliters uncontaminated High-Titer lysate, serological pipette, Oakridge tube, 40 microliters of nuclease, incubator, and 4 milliliters of phage buffer. The protocol for lab number 21 is to transfer 10 milliliters uncontaminated High-Titer lysate using serological pipette into the Oakridge tube. Place it into an incubator for half an hour after adding 40 microliters of nuclease, as well as inverting…

According to http://www.encyclopedia.com, DNA which stands for deoxyribonucleic acid is used for human genetic makeup. It has different sequences of bases and exist in human body. The sequence of it nucleotides are A, T, G, C; or, adenine, thymine, guanine, and cytosine, respectively. A DNA fingerprinting, is a DNA pattern that has a unique sequence such that it can be distinguished from the DNA patterns of other individual. The two major uses for the information is for personal identification…

Evidence and Analysis: The literature Ksp for calcium hydroxide is 5.02×〖10〗^(-6), which is a relatively large Ksp value. This goes against the “rules of solubility” that labels calcium hydroxide as insoluble. According to the “rules of solubility”, calcium hydroxide should not be soluble in water; however, our results reveal that it does have some degree of solubility at standard conditions. We know this because we started with an initial concentration of calcium hydroxide and no concentration…

percent error. There is a very small chance of there being a random error with the random uncertainty being only 0.4%. The pipette could be replaced with a volumetric pipette. This would allow for us to be able to measure the amount of water that is placed within. Therefore a drop would be more accurate as we could control the amount of volume that is lost from the pipette. Maybe it would've been better to use a different balance beam of the same model to determine whether the original balance…

volumetric pipette, add 3 ml of concentrated sulfuric acid to approx. 1500 ml water in 2 liter volumetric flask. Dilute volume with water. Standard Preparations: Accurately weigh 0.240g each std1 and std2 of sodium acetate tri-hydrate W.S. into 100 ml volumetric flask. Then dilute 25 ml to 50 ml with water. Sample Preparation: Dilute with water such that the concentrated of the sample lies within the concentrated range of the appropriate working standards for Plasma-Lyte A injection. Pipette…

research and develop new tools. They us over 700 million of dollars on research which is important for Thermofisher is important because it allows for them to create new and better technology. One of the types of technology that she had was a pipette. We had used pipettes in the PGLO lab at the beginning of the semester so that means that these devices are sought out by lots of…

Abstract- The main material and focus in this lab is the compound light microscope. During this lab you will check the microscopes by drawing what you see to make sure the high and low powers work properly. After you tested your microscope you take a toothpick and scrap it on the side of you mouth and examine what you see through the microscope, your final results should be a drawing of what you saw through both the high and low powered lens. Introduction- This lab is based on the…

The effect of caffeine on the heart rate of Daphnia pulex Introduction In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well. Carrie miller from university of…
