Practical report Microscope hardheaded report Date: 31/10/08 Aim: The main purpose of this pragmatic academic 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 prison cell photographic films exploitation the Leishmans foulness. During this practical the microscope that was employ was called the Zeiss binocular microscope. This microscope is specifically designed for notice 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 examine (coarse and fine), condenser iris, condenser control, and the filter tray. The method of staining that was use was the Leishmans stain that was employ was to stain the blood cells this was to enhance the visual percept and cont rast. The Leishmans stain is often used to identify leucocytes, malaria parasites, and trypanosomes; it is a conclave 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. after exploring the microscope and films and learning its functions, a dye blood cell film was placed on the map for o bservation. 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 dodging 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 touch of the practical were to simply remove the microscope...If you want to get a full essay, order it on our website: OrderCustomPaper.com
