Uses
- Absorbing Excess Liquids: Blotting paper is used to soak up excess liquids from surfaces, samples, or equipment, helping to maintain a clean work area.
- Transferring Samples: It can be used to transfer samples, especially in chromatography, where it helps in handling and separating substances.
- Wicking Action: In various applications like paper chromatography, blotting paper helps facilitate the movement of solvent and analytes by capillary action.
- Sample Preparation: Blotting paper can assist in preparing samples for further analysis, such as drying or concentrating biological specimens.
- Protecting Surfaces: It is often used to cover sensitive surfaces in the lab, protecting them from spills or contamination.
- DNA/RNA Blotting: In molecular biology, it is used in techniques like Southern and Northern blotting to transfer nucleic acids from gels to membranes for detection and analysis.
- Histology: Blotting paper can be used to absorb excess stains or reagents in histological preparations, ensuring clearer slides for examination.
- Electrophoresis: After gel electrophoresis, blotting paper can be used to wick away moisture from gels before transferring to membranes.
- Calibration: It can serve as a tool for calibrating certain equipment or for standardizing measurements in various experiments.
