Anesthetic (MS222) Solution Preparation
Anesthetic Solution (Buffered MS222) is commonly used to temporarily immobilize fish and amphibians.
Solution preparation
Solution preparation is an important skill in the laboratory, as it involves the accurate measurement and mixing of chemicals to create a desired solution. Here are some general steps for preparing a laboratory solution:
Gather materials: Assemble all the necessary materials, including a clean container for the solution, a calibrated balance or scale, a calibrated measuring cylinder or pipette, and the necessary chemicals.
Measure the solute: Use the balance or scale to accurately measure the mass of the solute, or the chemical that will be dissolved in the solution.
Measure the solvent: Use the measuring cylinder or pipette to accurately measure the volume of the solvent, or the liquid in which the solute will be dissolved.
Combine the solute and solvent: Pour the solvent into the container and add the solute. Stir the mixture until the solute is fully dissolved.
Label the solution: Label the container with the name of the solution, the concentration of the solute, and the date it was prepared.
It is important to follow proper laboratory safety guidelines when preparing solutions, including wearing protective equipment, such as goggles and gloves, and following any specific handling instructions for the chemicals being used. It is also important to accurately measure and record the amount of solute and solvent used, as this information is critical for reproducing the solution and for accurately calculating the concentration of the solute in the solution.
Carbenicillin Solution Preparation
Carbenicillin is an ampicillin analog with structure related to benzyl penicillin. It is effective against Gram-negative bacteria and exhibits limited activity against Gram-positive bacteria. Carbenicillin binds and inhibits the enzymes involved in the synthesis of bacterial cell wall. Since carbenicillin is less sensitive to β-lactamases than ampicillin, it is effective against ampicillin-resistant bacteria. It has … Read more
