Material and method: - quartz glass majestic - Grams atomic number 53 - Gloves - Slides - Loops - Safranin - ethyl alcohol - Bacteria - Burner - Slides - Loop Firstly, for gram stain the urine and bacteria are dish out over the parachute with a loop and let it air dry. Then the slueway is groove fixed over the shine over Bunsen burner. The slide is rinsed with crystal violet for 30 sec and washed rack up with water for 2 sec. the slide is then washed with grams iodine which works as sulfurous for a minute and the slide is washed once more to wash the excess.
