Laboratory equipment

Introduction The purpose of this lab was to determine the rate, function, and integrity of the heart during an exercise EKG. An electrocardiogram measures the electrical activity of the heart over time. In this lab a subject will exercise for about 15 minutes, not including rest times and the EKG will measure the heart’s activity. Methods Collect the following demographics for the subject: age, gender, height, MI, skinfold measurements, and weight. Locate the 10 electrode sites and shave the…

Materials and Procedure The materials that were used were the following: 4.268 grams of zinc sulfate heptahydrate, 2.586 grams of calcium acetate monohydrate, Analytical balance, 220 milliliters of deionized water, stir stick, two 100 milliliter glass beakers, one 250 milliliter glass beaker, filter paper, ring stand, glass funnel, and an Erlenmeyer flask. All of the materials listed above were obtained or taken into consideration before experimentation began. A piece of weight paper was…

For example, a volumetric pipette may be the most logical piece of equipment if the substance being measured needed to be moved from one container to another. Using the volumetric pipette would allow us to not only move the substance easier, but it also takes moderately accurate measurements. A specific situation in which…

Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be…

Methods There are many important factors to any experiment, including the materials. To continue, the quantity of materials for this experiment varies from a refrigerator to tweezers, but they all need to be included for the best results. First, the larger materials needed to complete the experiment are refrigerator, freezer, stove, one ice box, one scale which could be large or small, one blender, one cooking pot, one large jar or cup, and at least 400 milliliters of distilled water. Next, the…

Methods: Materials needed: Bottled water, control (tasteless) strips, PTC testing paper with ~ 0.003mg per strip, 1-inch strips of black licorice. 1. Provide each student with one large medicine cup filled of water. 2. Each student rinse his or her mouth of any residue prior to tasting the PTC paper with water to avoid misreading for data collection. 3. Give each student blindly a tasteless paper strip as a control. 4. Have each student again rinse his or her mouth of any residue then proceed…

A strip of magnesium (Mg) ribbon was cut with a scissor. Said piece had a length of 6 cm, and a weight of 0.071 g. The magnesium piece was rolled into a compact ribbon. After that, with copper turnings the mg piece was covered. Next, 700-mL of water was placed into a 1000-mL beaker. Then, the copper-wrapped magnesium was placed in the beaker. A 100-mL graduated cylinder was filled completely with water. After, said cylinder was covered with a small piece of paper towel over the entire rim, and…

I strive to enhance the quality of human life. The human race is plagued with disease, disorders and societal plights that treatment with traditional medicine would cease to assuage the recurrent issues. For example, diabetes is currently one of the top health challenges in the United States. The influx of diabetic patients will not decrease with insulin treatment alone, one must alter their injurious diet. Physicians are expected to treat patients based on symptoms. The analysis is then capped…

When Jim speaks of the “real, real” truth, this suggests the acknowledgement of his prior inability to face the moral conscious effects of the Patna affair, while the “real” truth suggests his seemingly moral redemption in Patusan. Prior to his time on the Patna, Jim was aboard a training ship fantasizing about saving passengers from sinking ships and other heroic feats, when a group of fellow seamen notified him of a nearby conflict. Jim stood to see the seamen rushing up ladders to the deck,…

article examines “laboratory operations” and “clinical pathology knowledge processes” to discuss the need for clinical pathologist to implement an institutional model through unified laboratory networks to protect their services. The author utilizes strengths, weaknesses, opportunities and threats (SWOT) methodology to study data processes and propose future strategies for clinical pathologist and laboratories to build laboratory service networks that offer exceptional organized laboratory…
