Filter paper is used to achieve sterility by trapping microorganisms and preventing their passage.

• Filter paper is a porous material that allows liquid to pass through while retaining solid particles.

• It is commonly used in microbiology laboratories to filter liquids and remove microorganisms.

• The filter paper acts as a physical barrier, preventing the passage of bacteria, fungi, and other microorganisms.

• It is often used in techniques like filtration sterilization, where liquids...read more

Water analysis as per IS standards involves testing various parameters to ensure water quality meets specified guidelines.

• Water analysis includes testing for parameters such as pH, turbidity, total dissolved solids (TDS), and microbiological contaminants.

• IS standards specify acceptable limits for each parameter to ensure water safety.

• Examples of IS standards for water analysis include IS 10500 for drinking water and IS 3025 for industrial water.

• Testing methods may include tit...read more
