Practical report Microscope hardheaded report Date: 31/10/08 Aim: The main purpose of this hard-nosed academic term 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 cellphone characterisations victimization the Leishmans foulness. During this practical the microscope that was use was called the Zeiss binocular microscope. This microscope is specifically designed for observant and illume cells. This practical was heavily based on the using the avocation functions of the microscope: The eye piece, prism, revolving nose piece, magnifier (*10, *40 and *100), clips, focus mark off (coarse and fine), condenser iris, condenser control, and the filter tray. The method of staining that was utilise was the Leishmans stain that was utilize was to stain the blood cells this was to enhance the visual percept and contr ast. The Leishmans stain is often used to identify leucocytes, malaria parasites, and trypanosomes; it is a faction 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 milieu was safe and avoid banquet any viruses or infections. later on exploring the microscope and films and learning its functions, a dye blood cell film was placed on the map for observation. Materials The fundamental materials that where used during this practical follow below: Ziess binocular microscope Red blood cell film Immersion oil Gloves Laboratory coats lens scheme wipes Leishman stain (eosin and methylene blue) Method This practical relied heavily on the microscope due to the culture of the practical. The first bas ic and essential prompt of the practical w! ere to simply remove the microscope...If you want to get a full essay, order it on our website: OrderCustomPaper.com
