What is the recommended type of immersion oil to use for microscopy?

The recommended type of immersion oil to use for microscopy is colorless, odorless, and has a refractive index closely matching that of glass, typically with a refractive index of 1.515.


Why gram staining is classified as differential staining?

Differential staining is the procedure that are used to distinguish organism based on their staining properties. Use of gram stain divide bacteria into two classes - gram positive which retain crystal violet stain purple colour, gram negative which lose their crystal violet and give pink colour. By this method we can differentiate two different types of bacteria having different cell wall composition that is the reason gram staining used widely as differential staining


What type of dye is used to stain the specimen when the acid-fast stain and the gram stain are used?

Both processes use 2 stains. The Gram staining process uses crystal violet as the primary stain and safranin as the secondary stain. Acid-fast staining uses carbol fuchsin as the primary and methylene blue as the secondary.


Why it is necessary to wipe off the immersion oil after using the oil immersion objective?

Leaving immersion oil on the objective can attract dust and debris, which can impact imaging quality and potentially damage the lens. In addition, it can cause the oil to harden and become difficult to remove, leading to maintenance issues. Cleaning the oil off after use ensures optimal performance and prolongs the lifespan of the objective.


What microscope objective is best to study bacteria?

A 100x oil immersion objective is best for studying bacteria under a microscope as it provides the highest magnification and resolution needed to observe bacterial morphology and structure in detail. Additionally, the use of oil immersion helps to reduce the refraction of light and improve image clarity.

Why is gram staining important?

It tells the microbiologist/clinician facts about the cell wall construction of the bacterium. This then indicates which antibiotics to prescribe if you are trying to get rid of a bacterial infection.


Why do you use on or slide to be examined with the oil immersion objective?

If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.

What is the advantage of the gram stain over simple stains such as methylene blue?

Gram staining highlights different bacteria types through the use of special dyes. It aids in the diagnosis of a specific organism and tells the difference between gram negative and gram positive bacteria. Simple staining is unable to highlight the exact organism.

What advantage does low power objective have over oil immersion objective?

A low power objective has a wider field of view and is easier to use because it doesn't require immersion oil. This makes it convenient for quickly scanning samples or observing larger structures on a slide without the need for oil immersion.

How do JCBs use hydraulics?

it runs with hydraulics .the hydraulics contains some oil immersion , fluids.


Why is it necessary to use a young culture 24-hr old culture in gram staining?

less than 24 hours old. Older cultures tend to lose the ability to retain stains.
