What is the principle of shake-flask extraction?
Shake-flask extraction is a liquid-liquid extraction technique used to separate compounds based on their solubility in two immiscible liquids, typically water and an organic solvent. In this process, a mixture containing the target compound is placed in a flask along with the organic solvent, and the flask is shaken to promote mixing. The target compounds preferentially dissolve in one of the phases, allowing for their separation from the other components in the mixture. After shaking, the two phases separate, and the desired compound can be collected from the phase in which it is more soluble.
How do you make 9 Grams per liters solution of NaCl?
Because you asked how to make a 9 g/L solution of NaCl rather than a 9.0 g/L, or a 9.00 g/L solution, to make a 9 g/L solution of NaCl you first weigh out 9 g of dry NaCl. The weight, actually mass, of the NaCl needs to be 9 g plus or minus 1 g. Next, add the 9 g of NaCl to less than one liter of water, perhaps 25 or 50 mL less. Stir or shake the flask very well for several minutes after all of the NaCl has dissolved, then bring the total volume up to nearly 1 L. Stir or shake the flask very well again, then add water if necessary to ensure that the total volume is one liter.
What is shake flask fermentation?
Shake Flask fermentation is a cheapest ans simplest technique to grow bacteria or fungi, aerobically, in small volumes of nutrient broth. The broth is poured into erlenmeyer flasks equipped with cotton-wool stoppers, and autoclaved. After cooling, some microbes are "seeded" into the flask, and it is placed on a Shaker machine. The shaking agitates the content and so ensures aeration, so that the microbes could breathe.
How do clean a beaker?
Acid washing it should do. I assume you are in a lab...in which case a 1:1 Hydrochloric Acid solution can be poured into the flask. DON'T FORGET TO PUT GOGGLES AND GLOVES ON. Put the lid on. Shake the flask and turn it to ensure all surfaces of the glass inside are being washed with the acid. Then, give it a good triple rinse with de-ionized water. If you are just at home, pour in some white vinegar and let it sit for a while. That should break up anything that's inside.
Why is it necessary to shake the volumetric flask at the end of preparation?
Shaking the volumetric flask at the end of preparation ensures that the solute is uniformly distributed throughout the solvent, resulting in a homogeneous solution. This mixing is crucial for accurate concentration measurements, as any concentration gradient could lead to errors in subsequent analyses or experiments. Additionally, thorough mixing helps to ensure that all of the solute has dissolved completely, which is essential for the precision of the prepared solution.
What are design aspects of shake flask fermentation?
Design aspects of shake flask fermentation include selecting appropriate flask volume and shape, ensuring proper sealing to prevent contamination, choosing an appropriate stirring mechanism and speed, controlling temperature and aeration levels, and monitoring and adjusting pH and nutrient levels as needed. These aspects are crucial for optimizing microbial growth and product yield in shake flask experiments.
