Having all these materials prepared before starting the slide preparation can make the process go much smoother and ensure better results. Make sure to follow the step-by-step guide carefully for best results.
Preparing the Slide
To prepare a slide for microscoping, follow these steps:
- Clean the slide: First, you need to clean the slide to ensure there are no dust or debris. Use a high-quality lens paper or a lint-free cloth to wipe away any material that may be on the slide’s surface. Also, clean your hands before starting the slide preparation process.
- Add a specimen: Place the specimen on the center of the slide. Make sure that the specimen is small enough to fit under the microscope’s objective lens.
- Add mounting medium: When the specimen is in place, add a mounting medium. This medium can be water or a commercial adhesive, such as glue or resin. If you want to use a commercial adhesive, make sure that it is suitable for the type of specimen being examined, and follow the instructions carefully.
- Place the cover slip: Place the cover slip vertically on one end of the slide, held at a ~ 45-degree angle. Slowly lower it over the specimen drop. Angle it slightly so that the mounting medium creates a meniscus that gradually sweeps across the slide, and avoid trapping air bubbles. Do not press the cover slip down all at once as it may damage the specimen. Carefully, press the cover slip down with a needle or a pipette tip.
- Remove excess medium: Use a tissue or a clean cotton swab along with a non-solvent adhesive remover to remove excess mounting medium or glue fluid that spills over the edges of the cover slip.
By following these simple steps, you can prepare a slide that is perfect for microscoping. Remember, proper slide preparation is critical in achieving accurate microscoping results.
Applying the Glue
