TEST FOR STARCH
Iodine test
Method:
First, we took a test tube and added 2cm³ of 1% starch solution. Then we added a few drops of iodine solution into the same test tube. Both the solutions were initially colourless, but the minute they both come in contact they reacted to give out a blue-black colour.
Material List:
1. Starch solution
2. Iodine solution
3. Test tube
4. Test tube rack
5. Goggles
6. Gloves
7. test tube
8. Pipette
9. Test tube holder
TEST FOR LIPID
Emulsion Test:
Method:
First, we took a screw top test tube and added 2cm³ of oil. Then we added 2cm³ of absolute ethanol into the same test tube. Then we closed the top of the screw top test tube. Then we shook the test tube vigorously. After this, we unscrewed the test tube and added an equal amount of water. The oil we added was yellow in colour and the ethanol was colourless. However, when we mixed them, they form some sort of tiny bubbles; soon they get cloudy and form a milky white colour. Then when we added the cold water, then we can see two layers forming inside the test tube, where the oil floats on top and water sinks below because the density of water is much higher than oil.
Materials Required:
1. Oil
2. Absolute Ethanol
3. Test tube
4. Test tube rack
5. Goggles
6. Distilled water
7. test tube
8. Pipette
9. Test tube holder
10. Screwed top test tube
TEST FOR PROTEIN
Biuret Test
Method:
First, we added 2cm³ of protein solution to a test tube. Then we added an equal volume of 5% potassium hydroxide solution and mix. Then we mix this solution and then add two drops of 1% copper sulphate solution and mix. When we mixed these solutions together, the colour changed to purple.
Material List:
1. Protein solution
2. Potassium Hydroxide
3. Test tube
4. Test tube rack
5. Goggles
6. Gloves
7. Test tube
8. Pipette
9. Test tube holder
10. Copper sulphate
TEST FOR REDUCING SUGAR
BENEDICTS TEST
Method:
First, we added 2 cm³ of a solution of the reducing sugar to a test tube. Then we added an equal volume of Benedict’s solution, the solutions colour was blue. We named this test tube (A). Next, we had to repeat the same experiment again but this time we did the test with another solution of the reducing sugar and named it (B). The next step was to keep both the test tubes that contained the

specimen labels and accordingly the proper tests are performed and reported to the correct patient. A registration process must be performed when you submit the sample to the laboratory, the sample cannot be dropped-off without this process. Collection It all starts with the collection of a proper blood or other specimen. A doctor, nurse, technician, or phlebotomist will draw your blood. Several tubes of blood may need to be drawn for different types of tests. Depending on your condition, your doctor…
How to become Medical Laboratory Technician Have you ever wondered what a Medical Laboratory Technician does? A Medical Laboratory Technician is also known as a clinical laboratory technician. They are scientists who perform a lot of essential laboratory testing that is critical to the detection, diagnosis, and treatment of disease. To be able to define the word of a Medical Laboratory Technician this essay will discuss the job itself and its working conditions, the skills and schooling needed…

respectively. The diagnostic laboratory in 2020 In the past decades, clinical diagnostic laboratories have undergone important changes with the introduction of molecular biology techniques and laboratory automation. These changes have evolved in response to clinical needs. One of the greatest challenges in modern medicine is the ability to provide accurate diagnostic laboratory tests in developing countries and in remote areas where conventional analytical laboratories are even lacking. This is due…
Determination of Molar Mass by Freezing-Point Depression When a solute is dissolved in a solvent, the freezing temperature is lowered in proportion to the number of moles of solute added. This property, known as freezing-point depression, is a colligative property; that is, it depends on the ratio of solute and solvent particles, not on the nature of the substance itself. The equation that shows this relationship is ΔTf = Kf × m× i where ΔTf is the freezing point depression, Kf is the freezing point…
000 = $149,000 - More orders from small distributors more handling and transportation costs - Increase from $500 to $6,000 per distributor for new point-of-sales material and promotional allowances. My recommendations: - With the increased number of small orders KMD may think about to consolidate several orders before shipping. This would give them a chance to reduce freight costs. - KMD can easily reduce the advertising costs. I think it´s not necessary to have the same advertising rate…
inevitably going to entail some kind of compromise. There will always be strengths and weaknesses, opportunities and limitations, to different approaches. Different methods will generate different kinds of data. Quantitative data are concerned with numbers, well, with quantities. We’re taking large amounts of information, such as people’s responses to a host of personality tests, or attitude questionnaires and transforming it into numerical values so that these can quickly be compared across large samples…
