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.

Pyronin Y(G) (PY) is a dye used for DNA staining. PY has orange spectral emission that is easily distinguishable from FITC and 7-AAD.
This dye has been used as a counterstain in saturated aqueous potassium alum and in a counterstain solution of 0.1% (w/v) with 5% aluminum sulfate for a Prussian Blue Stain for ferric iron. It has been used as a reagent for calcium in tissue where it forms a scarlet lake.
This “Mayer’s hemalum solution – for microscopy” is used for human-medical cell diagnosis and serves the histological and clinico-cytological investigation of sample material of human origin.
Immunofluorescence Quenching Solution is used in immunofluorescence and immunocytochemistry applications.
Cresol red is used as a tracking dye for DNA/RNA in agarose gel electrophoresis and protein in polyacrylamide gel electrophoresis.
Ethidium bromide is used to visualize DNA in agarose gels and in many cesium chloride gradient protocols.
It was originally used as an antimalarial compound. It kills the erythrocytic forms of malaria parasites at all stages of development but does not affect the sporozoites.
This solution is mainly used to determine the concentration of proteins in solution.
