During this practical the microscope that was use was called the Zeiss binocular microscope. This microscope is specifically designed for observe and illume cells.

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 surroundings was safe and avoid banquet any viruses or infections. by and by 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 arranging 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
