Practical report Microscope hardheaded report Date: 31/10/08 Aim: The main purpose of this matter-of-fact session was to read and become familiar of how to operate a Ziess binocular microscope. some other aim of this practical was to set up the microscope for critical scintillation to observe spotlighted gillyflower mobile phone films use the Leishmans foulness. During this practical the microscope that was employ was called the Zeiss binocular microscope. This microscope is specifically designed for observe and illume cells. This practical was heavily based on the development the avocation functions of the microscope: The eye piece, prism, revolving nose piece, magnifier (*10, *40 and *100), clips, focus chasten (coarse and fine), condenser iris, condenser control, and the filter tray. The method of staining that was utilize was the Leishmans stain that was utilize was to stain the blood cells this was to enhance the visual image and contrast. The Lei shmans stain is often used to identify leucocytes, malaria parasites, and trypanosomes; it is a combination of methylene radical radical blue and eosin. The eosin was used to colour the red blood cells, cytoplasmic material, cell membranes, and extracellular structures pink or red. The methylene blue was specifically used to make the nuclei more visible.

The cells that where observe were dead cells this was to ensure the purlieu was safe and avoid banquet any viruses or infections. later exploring the microscope and films and learning its functions, a dye blood cell film was placed on the map for observati on. Materials The fundamental material! s that where used during this practical follow below: Ziess binocular microscope Red blood cell film Immersion oil Gloves Laboratory coats lens clay wipes Leishman stain (eosin and methylene blue) Method This practical relied heavily on the microscope due to the culture of the practical. The first basic and essential trigger of the practical were to simply remove the microscope...If you want to get a full essay, order it on our website: OrderCustomPaper.com
