Introduction To Scanning Electron Microscopy At the completion of the prac‚ the practical experience of operating a scanning electron microscope is sufficient to operate the particular machine in the future. During the experiment‚ two different gold plated samples are analysed under the SEM and compositional and topographic information is identified and analysed. Both the information is derived by changing the working distance‚ accelerating voltage‚ aperture size‚ probe current‚ resolution and

BIO Microscopy‚ Mitosis‚ and Motility Lab Discussion Questions In the Microscopy‚ Mitosis‚ and Motility lab‚ the class used the Compound Microscope. The Compound Microscope helped examine the prokaryotic and eukaryotic cells‚ observe the different stages of mitosis‚ and compare modes of motility used by protists. The light compound microscope works with the aid of lenses such as the eyepiece. These lenses help keep the focus of the light on the eye. The fine and course adjustments also assist with

One on the base of the microscope and the other supporting the neck. 7) At what objective is it proper to use oil immersion? Only on objective 100x never on objective 10x or 40x 8) What are the proper two items to clean the microscope lens? And when do you clean it? To properly clean the microscope you clean

Exercise 1: Microscopy Nour Bairekdar Prof. Mary Flannery September 9‚ 2013 Learning parts and proper use of microscope‚ and the interception of images viewed through a light microscope Abstract: A compound light microscope uses two sets of lenses‚ ocular and objective‚ and employs light as its source of illumination. Through careful observation‚ we identified the various parts of a light microscope we found that the light microscope Ocular lenses which give 10x magnification

Virtual Lab Unit 3 1. Briefly describe the steps required to aseptically transfer bacteria from an unknown to a tube of liquid broth. You might have to research this using the "T" button (Tell Me More About...) To aseptically transfer bacteria from an unknown to a tube of liquid broth you have to flame the loop or wire before you begin to sterilize it. You then remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. When all this is done‚ you have to

magnification that can be achieved by an electron microscope. * explain the need for staining samples for use in electron microscopy Lesson 2 * calculate linear magnification of an image such as photomicrograph or electron micrograph Key words * Resolution= the ability to distinguish 2 separate points as distinct from each other. * Magnification= the number of times greater an image is than the actual object itself. Light microscopes have a low resolution‚ therefore if the magnification

Aim In this assignment I am going to carry out a practical examination on a plant (onion) and an animal (cheek) cell under a light microscope. The stain methods I am going to use are iodine for my onion cell and methylene blue for my cheek cell. Introduction All animals and plants are made up of cells. Animal and plant cells are made from millions of tiny cells‚ so small that we are unable to see them with our naked eye. Animals and plants have many features in common within a cell such

The Microscope Lab Brandy Talley PRCC Biology Lab Online June 13‚ 2013 Purpose: The purpose of this lab is to learn about different types of microscopes that we use today‚ learn the parts of the microscope‚ and how to properly use a microscope by exploring various slides. Materials: *Microscope *Letter “e” slide *Onion root slide *Bacterial capsule slide *Cheek smear slide Lab Notes: 1.What is the difference between a compound
