Intended Use
Used as diluent.
Composition
| Ingredients | g / L |
|---|---|
| Sodium chloride | 9.000 |
| Polysorbate 80 (Tween 80) | 0.500 |
Formula adjusted, standardized to suit performance parameters
Directions
Label the ready to use LQ200PD bottle. Inoculate the bottle with the pre-determined volume of the sample or 50-100 CFU of a known culture (as positive control) and incubate at 35-37°C for 24-48 hours.
Principle And Interpretation
Saline solution maintains the osmotic balance in microbial cells and helps to maintain the cell integrity and viability. Normal saline is used for preparing microbial suspensions for detection of antimicrobial agents, or to growth media used for disk susceptibility testing. It is also used in the preparing of stock solutions and serial dilutions of antimicrobial agents. Polysorbate 80 used as neutralizers.
Type of specimen
Pharmaceutical samples
Specimen Collection and Handling
For pharmaceutical samples follow appropriate techniques for handling specimens as per established guidelines (1,2). After use, contaminated materials must be sterilized by autoclaving before discarding.
Warning and Precautions
Read the label before opening the container. Wear protective gloves/protective clothing/eye protection/face protection. Follow good microbiological lab practices while handling specimens and culture. Standard precautions as per established guidelines should be followed while handling specimens. Safety guidelines may be referred in individual safety data sheets.
Limitations
- Saline solution does not support the growth of microorganism hence, further biochemical and serological tests must be carried out for further identification.
Performance and Evaluation
Performance of the medium is expected when used as per the direction on the label within the expiry period when stored at recommended temperature.
